Urban integration and landscape interlocking
The new building of the curative education centre in Senden presents itself as a finely tuned ensemble of three staggered structures that blend sensitively and naturally into the topography of the site. Together with the integrated sports hall and therapy area, the result is an architecturally and functionally multi-layered integration with the urban environment and the surrounding landscape. The differentiated structure and staggered heights of the buildings convey a sense of scale and allow for harmonious integration into the terrain from every perspective.
The main address of the centre faces south-east, where a generously designed forecourt with a clearly defined main entrance creates an inviting, representative entrance. From here, the communicative centre of the facility opens up, connecting all the main areas as its heart.
In the north-west, the outdoor play areas – including an all-weather pitch, a grass playing field and a school garden – form the scenic conclusion and underline the close connection between built space and open space.
Topographical integration and spatial diversity
The arrangement of the buildings follows the natural slope of the terrain and translates it into a structurally and functionally richly differentiated building landscape. The idea of interlocking continues inside: bright, spacious corridors, open lounge areas and diverse visual connections to the outside create an inspiring, light-flooded learning and working atmosphere. The clear structure of the buildings supports intuitive orientation and enhances the spatial quality.
Access and functional organisation
The central main entrance leads into a light-flooded foyer and break hall, which serves as the spatial heart of the building. The café and music rooms are directly connected here and can be flexibly opened up to the hall. The internal access is clearly structured and the routing is intuitive.
From the centre, the sports and therapy area with swimming pool and the children’s house are accessed on the ground floor. All functional areas are separately accessible if required and clearly separated from each other in terms of function. The central break hall connects all the main areas of the building via a spacious atrium. Social and recreation rooms are grouped around a gallery on the upper floor, supplemented by the primary and vocational school levels. The second floor houses the administration, the staff rooms and the secondary school, each of which can be identified as separate areas.
As in the rest of the building, recesses in the corridor areas create varied communication spaces with views of the outdoors and green inner courtyards. The open-plan concept supports a pleasant learning atmosphere and at the same time allows for a high degree of flexibility: the modular floor plan structure allows for future adjustments to the room layout.
A high proportion of green roof and façade areas not only improves the microclimate, but also functions as a retention area for rainwater. The basement houses technical and ancillary rooms as well as 28 parking spaces.
Arrival
The new school day begins on the forecourt at the junction between the existing building and the new special education centre. Overshadowed by a group of multi-stemmed, generously underplanted sweetgum trees with benches floating around them, the entrance plaza serves as both a passageway and a lounge area. Here, somewhat shielded behind the group of trees, are the bicycle parking spaces located near the entrance.
School landscape
We see the open space directly adjacent to the break hall as a school landscape that meets the space requirements of the room programme and is as green as possible. It is partially covered by large-crowned trees of the future and structured by lowered grass and shrub areas under the tree crowns, which, in addition to their insect-friendly abundance of flowers, also serve as retention and drainage areas. The central playground is paved with permeable concrete paving stones with partially linear lawn joints. The green classroom in the south-east, partially enclosed by low planting and directly adjacent to the school garden, offers space for outdoor learning away from the hustle and bustle of the playground. A mixed hedge of bird-friendly shrubs forms the boundary and transition to the agricultural landscape in the south. Where there is no need for playable and accessible lawns, sparse, two-cut meadows contribute to biodiversity. The southern area of the schoolyard is designed as an exercise landscape with a small playing field, a climbing wall and other exercise facilities.
Protected open space for the children’s house
The outdoor area of the children’s house is designed as a gently modelled play and adventure world, which, in addition to age-appropriate play equipment and sufficient paved areas, leaves room for nature-oriented play in the peripheral areas. Deciduous trees with rather sparse crowns ensure a pleasant climate all year round – plenty of sun when the trees are bare, sufficient shade in summer.
The edges of the peripheral areas are planted with edible and useful plants such as strawberries and blueberries, mint and lemon balm, as well as hazelnut bushes, which are robust enough for intensive use and also vividly integrate the seasonal changes into the educational concept.
Water management and biodiversity
In addition to meeting the requirements of the exercise, learning and play landscape, the outdoor facilities also fulfil the basic functions of a resilient and sustainable built environment. These include a maximum of structurally rich vegetation areas, water-permeable surface pavements and a rainwater management system as a recirculation system. The roof surfaces of the school building are designed as retention roofs. (18 cm substrate on the roofs (even with possible solar use), with retention boxes with a capillary wick system for optimal precipitation retention and evaporation). The substrate layer, in conjunction with the retention boxes, stores rainwater and makes it available to the plants. In the earth-bound vegetation areas, the rainwater is fed to the planting areas or tree trenches through the formation of the topography and is also collected in cisterns for service water use.
In addition to aesthetic considerations, all plantings are designed to make a valuable contribution to biodiversity. A targeted selection of different substrates in the peripheral areas creates a mosaic of ecologically valuable sites, which develops into particularly species-rich plant communities through the sowing of native wild herb seeds.

Arrival
The new school day begins on the forecourt at the junction between the new green corridor and the neighbourhood street coming from the north-west. Overshadowed by two multi-stemmed, generously underplanted sweetgum trees with circular benches floating around them, the entrance plaza is both a passageway and a place to linger. Those who arrive first will find a parking space for their bicycles close to the entrance on the east side, otherwise the large number of bicycle parking spaces are easily accessible under the grove of trees to the east.
School landscape
We see the open space directly adjacent to the break hall as a heavily landscaped school landscape on the ground floor, the first floor and the roof above the top floor. It is covered by large-crowned trees of the future and structured by lowered grass and shrub areas under the tree crowns, which, in addition to their insect-friendly abundance of flowers, also serve as retention and drainage areas. The central playground is paved with permeable concrete paving stones with partially linear lawn joints. The furnishings are multifunctional – the chill decks, located near the seating steps in the shade of the trees, are an informal meeting place even outside of break times. The open-air study room in the southeast, enclosed by a low hedge, offers space for group or individual study at long study tables, away from the hustle and bustle of the playground. The agricultural landscape to the east is bordered by a bird sanctuary planted with native trees and shrubs and a fringe of wild herbs suitable for the location. Where no playable or accessible lawn area is required, sparse, twice-mowed meadows contribute to biodiversity.
Exercise landscape
On the roof of the gym, the school landscape becomes an exercise landscape – from various calisthenics and obstacle course activities to floor trampolines, there is everything you need to combine sport and fun. Of course, there is also space for spectators: long benches where people can sit together on the backrest and more intimate seating shells for two form the ‘grandstand’ for the action on the roof. The areas are framed by drought-resistant grasses and shrubs. They are positioned so that loads are distributed as efficiently as possible at the edges.
A wide, green staircase with integrated seating steps leads to the streetball court and the boulder sculpture on the ground floor level.
Water management and biodiversity
In addition to meeting the requirements of the exercise and learning landscape, the outdoor facilities also fulfil fundamental functions of resilient and sustainable area development. These include a maximum of structurally rich vegetation areas, water-permeable surface pavements and rainwater management as a recirculation system. The roof areas of the school building are designed as retention roofs. (18 cm substrate on the solar roofs, up to 50 cm on the first floor and in the school garden area, with retention boxes with a capillary wick system for optimal precipitation retention and evaporation) The substrate layer, in conjunction with the retention boxes, stores rainwater and makes it available to the plants. In the earth-bound vegetation areas, the topography of the site allows rainwater to be fed into the planting areas and also collected in cisterns for service water use. During heavy rainfall events, excess rainwater is collected in trough infiltration systems (infiltration cascade) in the planting areas.
In addition to aesthetic considerations, all plantings are designed to make a valuable contribution to biodiversity. Through the targeted selection of different substrates, a mosaic of ecologically valuable sites is initiated, which develops into particularly species-rich plant communities through the sowing of native wild herb seeds.
Extension and renovation of two primary schools | Sassenburg
1st Prize | Extension and renovation of two primary schools
Sassenburg
In collaboration with Kauffmann Theilig & Partner
The primary school in the colourful triangle in Sassenburg is gaining a new spatial and educational quality thanks to a precisely positioned and atmospherically dense extension. The existing triangular stand-alone building with its striking, self-contained form is complemented by a single-storey extension on the south-east side – not by adding storeys or external satellites, but by an architecturally related structure that coherently enlarges and thus extends the triangle without losing its identity. This measure not only creates additional space, but also light-flooded, open spaces and a new cluster structure: four of the twelve new classrooms each form small educational units together with the open learning areas between them. The fan-shaped arrangement of the rooms allows for generous daylight and a close interconnection between indoor and outdoor spaces.
The previously difficult-to-use inner courtyard is transformed into a climatically protected centre of the school – the new market square – by a careful roofing with skylights. In future, the library and the computer room will be located there, both centrally located and with high-quality lighting. Further selective additions within the existing structure – such as the new canteen on the west corner – fit in organically and with minimal construction effort. The canteen itself is ideally positioned: right next to the entrance with generous indoor and outdoor areas, short distances for food distribution, direct delivery from outside and flexible expandability towards the corridor thanks to mobile walls. A stage and a connection to the music room can also be easily integrated.
The construction process is designed so that the school can remain in operation throughout the entire process – without an interim solution in the traditional sense. During the seven-week summer holidays, the existing components on the south-east side will be dismantled and adapted, and a more efficient façade will replace the dilapidated existing façade. At the same time, the new classrooms will be produced as prefabricated wooden containers, which will be positioned directly at their final location at the end of the summer holidays. This means that the new school year will begin in a part of the new building that is already usable. The remaining renovations – such as the canteen, the closure of the inner courtyard, infrastructure measures and work on the west façade – will be carried out over the following ten months while the school remains in operation. The remaining measures and final connections will be completed during the following summer holidays. After a year and a half, the new school building will be completely finished.
The existing school, as ambitious as it once was, proved to be overly technical and maintenance-intensive. The new design deliberately focuses on functional low-tech solutions with high didactic potential: window ventilation with optimised cross ventilation makes mechanical systems in the classrooms superfluous. Existing ventilation systems are only used where they make sense – for example, in the kitchen, canteen and interior rooms. Heat pumps with renewable energy sources such as foundation absorbers, geothermal probes and bored piles are used for heating and cooling. Static air conditioning is provided by ceiling elements, while photovoltaic systems on the roof enable the school to operate almost entirely self-sufficiently in terms of energy.
The materials and design are based on the existing structure and functionality. The new classrooms consist of self-supporting wooden containers, complemented by a wooden slat structure that completely closes the geometric triangle in the site plan. These slats also serve as weather and sun protection thanks to the photovoltaic layer above them. The roof surfaces are being renovated and the ventilation system integrated into the new roof shape. In the existing building, the façades will be made less transparent, with light-directing slats, printed glass elements and effective sun protection devices.
Last but not least, the architecture reflects the actual ‘colourfulness’ of the triangle: the students and the natural, changing landscape. Glazed, shiny and printed components capture the colours and movements of school life and the surrounding area – a lively, diverse picture that changes with the seasons. The result is a new school building that showcases the friendly, lively interaction in a clearly defined but open architectural framework – unpretentious, sustainable and full of quality of life.
Open space
The existing school grounds, nestled in the eastern residential area, are characterised by an open structure with several access points and sweeping views of the surrounding landscape. The new concept takes these positive features and integrates them into a modern, sustainable design.
The new design surrounds the triangular school building with dense, varied planting and forms a new, robust and lively playground. The organic shapes of the planting areas not only create an exciting relationship with the school building, but also internal, protected areas. The plantings open up specifically at the main entrances – the entrance via the street ‘Am Felde’ and the side entrance via ‘Bokensdorfer Weg’ – thus creating inviting entrance areas.
The schoolyard develops from the existing structures of the outdoor facilities and the new extension into a coherent outdoor space that wraps around the building. It thus develops from an extensive play area in the west of the building to a natural quiet area in the east. The break area to the west of the building is characterised by opportunities for romping, digging and playing. Here, the children are offered various opportunities for physical activity, such as a large climbing sculpture, basketball hoop, table tennis tables and additional areas for free play. The existing outdoor classroom is also integrated here and provided in a quieter, green, shaded area, which is combined with a sound garden.
Towards the east, the schoolyard develops into a shady retreat. Here there is another green classroom and green niches and areas for gardening. The furniture throughout the school grounds invites children to spend time in different ways. This allows groups of pupils to gather, interact and move around everywhere. The green spaces are designed to become denser and higher towards the edges, reducing visibility into the school grounds. The varied and site-appropriate planting areas promote ecological learning processes and sensitise pupils to environmental issues. Additional green islands respond to climatic challenges. The open space thus not only meets the requirements of a modern schoolyard, but also promotes a conscious engagement with nature and sustainability.
In the area of the northern main access, a sufficient number of bicycle racks will be retained. Access to the waste disposal area and the small boiler house will be integrated.

Urban planning concept
The four-storey new building for the molecular biology laboratory fits into the overall concept of the existing master plan as another precisely placed building block. The upper part of the building consists of a staggered technical floor and a roof terrace. Along Planstraße E, the main entrance is clearly accentuated by a recess on the ground floor, creating an inviting entrance. The landscaped forecourt with integrated bicycle parking spaces emphasises the entrance area and creates a pleasant atmosphere. Additional access points are planned in the south-western area along Campusallee and along the connecting axis between Planstraße E and Käthe-Kümmel-Straße. These will enable internal deliveries and provide access to a side entrance. To strengthen the campus identity, the ground floor around the central atrium is primarily arranged for communicative and public-oriented functions such as seminar areas, computer pools and an exhibition area in the foyer. In the urban context of the surrounding institute buildings, the façade presents itself as a finely structured ribbon façade with integrated photovoltaic elements that also serve as sun protection. Vertical façade elements add rhythm to the building envelope and serve to guide the external sun protection system. Wooden elements are planned for the parapets, which lend the overall appearance a warm, material-appropriate accent and underline the building’s sustainability strategy.
Internal and external access, spatial organisation
The new building has a central access system that connects all functional areas via short routes. The communicative heart of the building – a spacious interior with open communication zones – facilitates orientation and promotes interdisciplinary exchange. All essential vertical access elements, such as emergency staircases, technical shafts and sanitary areas, are grouped around this core on all levels. In addition to general functions and central seminar rooms, the differentiated inner courtyard with its projections and recesses and the adjacent terrace areas form the green centre of the building. On the ground floor, the exhibition area, seminar zones and functional rooms such as practical training areas, an electrical workshop and computer pools are located around this courtyard.
In addition to the emergency staircases, the upper floors are accessed via a continuous gallery-like staircase that leads directly to the communication centre. Changing seminar zones, terraces and open communication areas on all levels invite informal exchange. The staggered arrangement within the floor plans creates an exciting inner courtyard that structures and enlivens the building ensemble as a connecting element. Laboratories, evaluation areas and flexible office spaces are organised logically and according to use within the floors and are optimally connected to the access routes.
The overall result is a finely balanced spatial structure with a central communicative heart and quiet, decentralised work areas – a structure that promotes both exchange and concentrated work.
In the interests of ecological sustainability, the roof area is extensively greened with native grasses and shrubs to promote biodiversity. In addition, employees have access to another roof terrace as a recreation area with a view over the campus. A large-scale photovoltaic system is also planned to supply the building with its own electricity, making a significant contribution to its energy efficiency.
Architecture, construction and materials
The building is designed as an optimised hybrid construction in which materials are used specifically where they make functional, economic and ecological sense. The choice of materials is based on the resource-saving concept of recycling, which is to be effective throughout the entire life cycle. The primary structure will be constructed as a material-efficient reinforced concrete skeleton using semi-prefabricated elements. The use of recycled concrete is planned or being examined where it is structurally and economically feasible. The clear and consistent structural design allows the use of prefabricated building elements and enables a robust, economical construction method and an optimised construction process. The basement, stairwell cores, point-supported ceilings and fire protection components are constructed using solid construction methods. The building is reinforced by the central access and technical cores.
The façade elements are planned to be highly thermally insulated, prefabricated timber constructions with vertically structured timber cladding. The vertical sword structure in the area of the window bands serves to accommodate the integrated photovoltaic elements and at the same time structures the façade appearance. The horizontally arranged PV modules also serve as structural sun protection and integrate the necessary fire protection.
The static system – combined with a high degree of prefabrication – forms the basis for an economical, time-efficient and durable construction method. The laboratory grid is defined as 1.20 m. This results in construction grids of 3.60 m, 7.20 m and 10.80 m. Wide-span ceilings are supported by joists. The window division follows the expansion grid and allows flexible connection of mobile partition walls for variable room structuring.
The interiors are characterised by a clear material aesthetic: light-coloured wall surfaces, wooden surfaces and glass create a high-quality, light-flooded room climate. In combination with coordinated floor coverings and a differentiated colour and material concept, rooms are created that are equally suitable for concentrated individual work and open teamwork.

Guiding principle and urban planning
The new building for the school campus consists of three simple, interlocking volumes for the two uses, secondary school and junior high school, as well as the shared areas in between. Due to the different space requirements, the three cubes differ in area and height, resulting in a differentiated overall ensemble in which the individual uses remain clearly distinguishable. The building for the secondary school is located in the western part of the site, while the one for the secondary modern school is in the eastern part. With four and five upper floors respectively, both towers above the three-story cube for the communal areas and specialist classrooms, thus preserving the independence of both schools as separate organizational units. The building volumes for the secondary school and the communal areas each have inner courtyards to ensure that all rooms receive natural light. The arrangement of the buildings allows the new construction to be built in two phases, eliminating the need for costly interim solutions. The height gradation of the school campus follows the eastward-sloping topography of the site, minimizing the building’s footprint. Due to this topography, another partially buried “garden level” is created to the southwest under the ground floor, which accommodates additional uses in all areas. The two schoolyards can thus be arranged on different levels, extending to the southwest (secondary school) and northeast (middle school) adjacent to the building structures, thus following the basic idea of separate organizational units. Both schoolyards have the required covered areas thanks to undercuts in the building volume. The clear color scheme of the facades follows the color code for the two schools, while the central building for communal use has its own color code. The Voss Arena is getting a new entrance building, which not only allows access from the schoolyard but is also accessible directly from the street via an additional floor. The arena will thus have its own address and visibility from the street, and therefore access independent of the school grounds.
Open space
The site is accessed via a shared entrance from the north. A second entrance is provided from the south-west, via the entrance to the residential area to the south. The required parking spaces are still located here, but have been rearranged. The shared sports fields are located in the southern green belt, as are the ‘green classrooms’, and surround the schoolyards. Taking into account the need for maximum flexibility in the use of the schoolyard areas, green islands and tree plantings are also planned here to enhance the quality of the environment and improve the microclimate. The outdoor classrooms of both schools are also embedded in the green setting. Here, too, the topography is utilised and made visible with seating edges. Despite the sloping location, areas have been created that are available for rainwater retention. Lighter, but non-glare colours were chosen for the surfaces, as these absorb less radiant heat.
Building structure
The three equivalent main entrances each face the northern forecourt, are marked by building recesses and are therefore easy to find. The organisational principle of both schools is identical: the main entrances lead to the administration and staff areas located on the ground floor and to the vertical main access cores, which are arranged in the overlapping areas of the cubes. These cores also serve as transitions and connections to the centrally located shared facilities, such as the auditorium and cafeteria, and the specialist classrooms on the upper floors. At the ends of each building, there is an external staircase that serves as a second escape route. Both schools have ‘floor foyers’ on the upper floors, which provide access to the learning cluster areas. The staircases and foyers are designed differently depending on the school, which emphasises the respective identities of the schools and facilitates orientation. On the third floor, both schools have a roof terrace on the roof of the central building. The central building houses the forum, the library and the all-day area on the ground floor, while the garden level houses the two-storey auditorium and the canteen, as well as music rooms. The spacious open staircase with seating steps in the forum connects both floors. The forum and canteen are assigned to the respective schoolyards as rain break areas. The upper floors of the central building house the specialist classrooms that can be used and are required by both schools.
Materiality, construction & sustainability
The entire building above the garden level, which is designed as a solid structure, is conceived as a wood-concrete composite construction. The access and stairwell cores are constructed of reinforced concrete to meet fire protection requirements and at the same time ensure the bracing of the building. In the remaining areas, a concrete ceiling will be laid on wooden beams in a 1.25 m grid. These beams are connected to main beams in the direction of the facade and corridor walls, which rest on supports in a 3.75 m grid. This construction minimises the amount of material required for the ceilings. All wooden components are dimensioned to ensure fire protection through combustion. The materiality of the construction can thus be made visible and tangible in all areas of the building. The skeleton construction allows for a flexible response to all requirements of the room programme, and subsequent adjustments to room sizes are easily possible. The construction grid is also carried over to the exterior via the façade. Vertical wooden pilaster strips divide it, and in the base areas this grid is replaced by the main column grid of 3.75 m. Striking cantilevered window sills as the upper edge of the parapet areas form the horizontal counterpart. The varying cladding of the parapet bands made of profiled ceramic elements gives each building its own identity. The colour scheme of the pilaster strips, parapets and other closed façade areas is largely monochrome, following the colour concept for the individual areas of use: secondary school (blue), middle school (green) and secondary modern school (red). All rooms have external sun protection. The roof of the central building is intensively greened and can be activated as a retention roof; each school has its own terrace here. The roofs of the school buildings are extensively greened and equipped with large-scale PV systems. Heat is supplied by a heat pump, which can also be used for cooling in summer. Most of the rooms are equipped with underfloor heating. The optimal orientation of the rooms – the majority face north or south – minimises solar gain in summer. The proportion of glazing in the façade was designed to reduce the use of artificial lighting.

Urban integration and interlocking with the landscape
The new children’s house with the extension of the school building on the Schorndorf educational campus is a scaled ensemble of individual buildings with a common centre, the future communicative heart of the new buildings. In the context of the existing buildings, these form an arrangement in a free network that interlocks with the open spaces and offers well-proportioned open spaces.
The school extension for the Fröbelschule is connected to the new building in a natural way. The kindergarten will have its own separate entrance in the southern part of the site. The design concept of interlocking landscape and building is also reflected in the interior of the ensemble. The orderly structures of the buildings create very well-organised interior sequences and exciting spatial relationships from the inside to the outside and vice versa. These characteristics make the new building an emblematic, varied and creative building for children and teachers. Another important aspect of the concept was to locate the uses in recognisable structures, whereby the extension to the school complements and strengthens the existing campus concept and its facilities.
Outdoor facilities
Arrival
The start of the new school and kindergarten day takes place on the forecourt. Planted with a multi-stem, generously planted amber tree with a round bench hovering around the tree, the entrance plaza is both a passageway and a recreation area. The western part of the forecourt along the lay-by and in front of the main entrance offers generous space for waiting, boarding and alighting, while the eastern part extends the open space in front of the dining hall, offers space for the playing field to be relocated and extends the existing playground of the Fröbelschule to the east.
Play yards
The positioning of the buildings allocates clearly defined open spaces to the individual kindergarten and school areas. A linear play sculpture with integrated sand play, climbing and retreat options and a slide closes off a western play yard to the property boundary and arranges the play options in such a space-saving way that there is plenty of room for romping and dashing and for a bobby car track outside the fall protection area. The northern play yard in the spatial context of the Christian Morgenstern School is designed as an exercise yard with a range of play equipment adapted to the age group. The school garden with its opportunities for barrier-free gardening and outdoor lessons is located in the north-east courtyard.
Ecological aspects
We see the open space on the entire site as a heavily greened play and school landscape. It is covered by large-crowned future trees and structured by sunken areas of grasses and shrubs which, in addition to their insect-friendly abundance of flowers, also serve as retention and seepage areas. The paved recreation areas are paved with permeable concrete paving, with linear grass paving at the edges. All shrub plantings around the edges are planted with native trees and shrubs and a border of native wild herbs to protect birds. Where no playable and walkable lawn area is required, lean, double-cut meadows make their contribution to biodiversity. In addition to aesthetic considerations, all planting is carried out in such a way that it can make a valuable contribution to biodiversity. Through a targeted selection of different substrates, a mosaic of ecologically valuable sites is initiated, which develops into particularly species-rich plant communities through the sowing of native wild herb seeds. Modelling the terrain into shallow depressions for retention and infiltration further increases the diversity of the microsites.
Water management and biodiversity
In addition to the requirements of the exercise and learning landscape, the open spaces also fulfil fundamental functions of resilient and sustainable area development. These include a maximum of structurally rich vegetation areas, water-permeable surface paving and rainwater management as a circulation system. The roof surfaces of the school building are designed as retention roofs (approx. 20-40 cm of substrate and retention boxes) to optimise rainwater retention and evaporation. The substrate layer in combination with the retention boxes stores the rainwater and makes it available to the plants. In the ground-bound vegetation areas, the rainwater is channelled to the planting areas through the formation of the topography.
Daycare Centre Hegge | Waltenhofen
2nd Price | Daycare Centre Hegge
Waltenhofen
In collaboration with Benkert Schäfer
Local spatial setting and integration into the surroundings
The district of Hegge is characterised by open development without spatial densification towards the centre. Peripheral zones have been densified by residential development, while the centre lacks a place for the community. The new day care centre is intended to resolve this tension and seize the opportunity to create a new centre. The proposed location of the new daycare centre in the immediate vicinity of the church and local supermarket will reorganise the village centre and create a lively village square. In order to bring the church back to life on the village square, buildings that are no longer necessary will be removed. The deliberate placement of trees divides the new village centre into different areas of use. A small pub with a beer garden and shady areas invite people to linger. A cooling fountain improves the microclimate, especially on hot summer days. The new daycare centre itself is an open house for the children on the village square. With a sequence of paths and squares, it continues the village square inside and allows the different uses of the daycare centre to be experienced. The building makes clever use of the local topography – the multi-purpose room directly at the entrance is an address and open to the whole community, while the kindergarten and other communal uses are organised around a shared inner courtyard at the centre of the building. The crèche for the youngest children is organised in the plinth below, with direct access to the garden. An open and rhythmic setting in the scale of the surrounding buildings is proposed for the residential building. Following the principle of the clustered village, small outdoor areas are created that can be used communally.
Access and traffic
The main access to the daycare centre is via the village square and Veitser Straße. Kiss & Ride car parks will be created along the road to ensure that children can be picked up and dropped off safely. Access to the garden to the south and east and an entrance from Veitserstrasse, as a link to the day-care centre opposite, round off the connection with the surrounding area. Parking for daycare centre staff and residents of the new residential development is provided in the shared underground car park, which is also accessed from Veitser Strasse. Additional parking spaces for short errands in the village centre are located to the north of the village square along Industriestrasse. The residential street ‘Am Pfarrgarten’ will therefore remain largely reserved for residents and thus offers quiet access to the individual residential buildings via the shared green. A new footpath connects the village square with Marienplatz and creates a direct pedestrian axis for the residents of the eastern ‘Illerbogen’ area. The entrance to the new daycare centre is located on the village square, where there is also covered bicycle parking – creating a meeting place for teachers, parents and children. The kitchen will be delivered via an additional entrance on Veitser Straße.
Typology and spatial organisation
The two-storey day care centre blends harmoniously into the existing hillside location. The entrance area and the foyer with multi-purpose room are located on the ground floor, facing the centre of the village square. The general area with kitchen and dining room as well as the kindergarten are accessible from there. The large exposed seating staircase in the foyer leads to the garden level below and, in addition to providing access, also serves as a reading staircase and library.
An atrium in the centre of the building provides sufficient lighting and offers further sheltered outdoor areas for the children. The crèche is located on the garden floor with direct exits to the toddler play area in the garden. The workroom and studio are centrally located and have their own outdoor area in the atrium. The staff area is also located on the garden floor, with its own exit to the outdoor seating area. The underground car park, storage area and ancillary rooms are economically located on the slope side of the garden level.
Orientation towards the open space
All of the daycare centre’s group rooms face south-east towards the garden. The children in the kindergarten can access the garden via an external staircase in the south of the building or barrier-free via the lift. Various play areas and a large play element await them there. The area of the former parish garden will be integrated into the new play area. The younger children in the crèche have direct access to the garden via their group rooms. The outdoor area of the staff area leads via an atrium to a small terrace.
Outdoor facilities
The open space of the new day care centre creates a lively, green environment,
that blends harmoniously into the existing village structure. The preservation of the existing trees creates a natural atmosphere, provides shade and makes a valuable ecological contribution. Careful modelling of the topography creates varied outdoor areas that take up the natural terrain formation. A multifunctional play element structures the space, serves as a separation between the areas and at the same time promotes the children’s motor skills. It integrates additional storage areas for outdoor play equipment. The nursery and crèche areas are clearly defined by targeted planting, while terrace-like open spaces allow flowing transitions between indoor and outdoor areas. This creates a well thought-out. This creates a well thought-out combination of nature, play and community that optimally supports the educational use of the outdoor space.

In the construction sector, and therefore also for cities and municipalities, there is a growing responsibility to focus on sustainable concepts when realising new buildings. The building proposed here is therefore sustainable, economical and forward-looking.
TOPOS and open space – sustainable inner-city development is climate-resilient and can adapt to climate change through blue-green settlement strategies. Green roofs and, in some cases, green façades reduce heat loss and improve the microclimate through absorption cooling in summer. A house tree and retention areas in the inner courtyard support these measures. Rainwater can be retained on site via cisterns, utilised and excess precipitation can seep away in soakaways on the property

Urban planning idea
The new training academy gives the Karlsruhe Chamber of Crafts the opportunity to present itself in the context of constant economic, technological and social change with a new, contemporary and modern learning and working environment.
In accordance with planning and building regulations, the new building will be positioned along Johann-Georg-Schlosser-Straße. By staggering the structure, the building volume is structured and functionally organised.
The main entrance to the building is located in the centrally positioned, striking three-storey section of the academy, giving the educational academy an easily recognisable appearance that is appropriate to the location.
An entrance square is located in front of the main entrance, providing a short link between the car park at the side and the main entrance.
Inner courtyards
The workshops are arranged around central courtyards. This creates a varied circulation area with interesting views when moving through the workshop areas. In addition, widened areas in front of the courtyards and the courtyards themselves offer space for communication and relaxation.
Open space
The Bildungsakademie in Karlsruhe is reached via a spacious forecourt. Past small green islands and numerous trees, the entrance is clearly recognisable. A combination of greenery and seating areas creates an attractive place to meet and offers the opportunity to spend time in the urban centre under shady trees.
The collective relocation of the car parks to the western part of the site creates a calmer area in front of the academy for pedestrians and cyclists. This is reinforced by bicycle parking spaces in front of the entrance.
Deliveries are made via the southern open space. Together with the entrance to the petrol station, deliveries can take place separately from the rest of the Academy’s use. A strip of vegetation in combination with a fence restricts accessibility and creates a clear spatial separation. To further enhance this area, however, numerous trees will be planted. Small niches with seating areas are created under this tree canopy in combination with extensions of the green belt.
A central point in the outdoor area planning is the increasingly important rainwater management in order to ensure that the educational academy remains a modern location for many years to come. Generous retention and infiltration areas were therefore planned.
To the south of the new building, the retention area is located in a combination of several troughs. This allows excess rainwater from the site and neighbouring areas to be collected, evaporated and seeped away.
A green belt around the car park deck also allows some of the rainwater in the western part of the site to be absorbed. The remaining water is channelled into the long infiltration area to the south.
The three inner courtyards with green and seating elements also support the handling of precipitation through direct infiltration areas.
Roof and façade design
The roofs of the single-storey building areas and the storey ceilings of the central building are planned as timber-concrete composite ceilings on a construction grid of 5x5m. If required, the construction grid can be extended to 7.5×7.5m or 10x10m and the construction supported by beams.
The façade elements and interior walls are planned in timber frame construction.
The materiality of the façade continues the timber construction method. The façade surfaces are clad with timber panelling. Greenery is proposed for parts of the façade.
Biodiversity and rainwater management
In addition to the functional requirements of the educational academy, the open spaces also fulfil fundamental functions of resilient and sustainable area development. Rainwater management, water-permeable surface paving,
vegetation areas rich in structure, biodiversity and cohabitation take centre stage here.
centre stage. The building roofs will be intensively greened with regional seeds. The 30 cm thick substrate layer retains rainwater almost completely through storage and evaporation. Excess rainwater from the roofs is collected in cisterns and made available as service water for the building services and the green areas.
The outdoor areas are provided with a comprehensive rainwater management system. For this purpose, the rainwater is channelled into the planting or shrub areas so that it can be collected there and seep away locally. Excess rainwater during heavy rainfall events is channelled into retention areas.
The open green spaces, with a large proportion of species-rich flowering zones, with heat-tolerant extensive shrubs and grasses, serve as food and habitat for bees and insects. Free-growing hedges of native trees and shrubs are planned along the edges; they form the boundary of the space, reduce noise and provide protection. Interspersed fruit trees increase the biodiversity of the open space. A green space for people, animals and plants.

Key idea
The urban design for a district centre combines a targeted building configuration with the existing buildings, striking groups of trees with an inviting green neighbourhood square along Forstbachweg.
Urban development and open space
The Boomerang House for meeting, education and living forms the new district centre with a neighbourhood square and park along Forstbachweg thanks to its urban design, together with the youth centre and the gymnasium and multifunctional hall. The planned greening with old and new trees contributes to the creation of an inviting, versatile and protected open space. The ground floor of the Boomerang building is intended for communal, social and commercial uses in order to revitalise the centre of the neighbourhood and visibly promote social interaction. The tower and the atrium house complete the collage and together form a green, semi-public residential courtyard. This residential courtyard can be further enlivened by spacious communal areas on the ground floors, making it ideal for communal living models. A spacious passageway in the Boomerang House connects the open, park-like courtyard with the neighbourhood square. The TOGO House at the end of Togopark forms a striking spatial accent, provides social security and utilises the existing unused brownfield site for residential and commercial use. The noise-intensive uses for a ball sports field and a skate park are being created on the school grounds along Forstbachweg and, together with the supermarket, now complement the new Forstfeld centre along Forstbachweg. These measures will help to reduce noise pollution in the neighbouring residential areas.
Development
Car traffic in the entire neighbourhood will be significantly reduced in order to prioritise public open and green spaces as high-quality recreational areas for the residents of the Forstfeld district. Forstbachweg will be converted into a 30 km/h zone in some areas (e.g. Leuschnerstraße). The existing access road and the car parks for the daycare centre will be removed and relocated to Heinrich-Steul-Straße. The areas of the existing car parks will be converted into outdoor play areas for children. The resulting elimination of the break between the youth centre and the adjoining areas will make a significant contribution to moving the Forstbachweg building into the urban context and onto the neighbourhood square. The required parking spaces will be provided in a short cul-de-sac and along Heinrich-Steul-Straße. If required, an underground car park can be built under the tower house. Bicycle parking spaces are provided in the open space with hangers and a lockable bicycle shed. In addition, the lifts in the residential buildings are suitable for bicycles, so that bicycles can also be parked safely and conveniently in their own cellars. It is possible to cycle through the new centre of Forstfeld at a speed of 10 km/h. As the Boomerang House is only planned with three storeys and the tower house and the atrium house will be equipped with safety staircases, no complex fire service bypasses are necessary.
Open space and ecology
The urban development concept results in a high proportion of green spaces with characterising grove structures in the existing buildings, sophisticated new planting and attractive squares. Of particular importance for the concept of the open spaces is the neighbourhood square with a high quality of stay and the connection between the open spaces.
The generous green spaces and the preservation and planting of new trees fulfil the increased need for urban greenery due to climate change. These measures serve as a buffer against heat stress and heavy rainfall events and also act as a dust filter. Wherever possible, rainwater is channelled into open retention basins and made visible. At the same time, the run-off of rainwater from the roofs is minimised by using green roofs as buffer storage.

Key idea and urban development concept
The new station building with adjoining bicycle parking garage marks the new station entrance and access to the tracks with an appropriate high point and sets an example for the Wiesdorf/Leverkusen-Mitte station district. At the same time, the new development forms the transition and an appropriate prelude to the south to the newly developed post office site.
The cubature of the station building develops, stepped down like a terrace, out of the single-storey long building of the bicycle parking garage. The development is characterized by intensively greened roof and façade areas and represents a visible contribution to urban development. The bicycle parking garage is subdivided into several parking areas. The angled arrangement of the bicycle boxes defines the space towards the central bus station and yet does not place the bicycle highway in the second row. With the new possible crossings, the cycle highway is connected to the central bus station/station square and not relegated to the second row behind the bicycle parking garage as a mere “through lane”. The cantilevered roofing in the area of the first floor offers protection for additional bicycle parking spaces and the possibility of storage. The building can be constructed in two separate parts.
Open space concept
Opposite the large traffic area of the bus station, the new station forecourt acts as a green link between the unvegetated functional area – the new station and office building and Rialtoboulevard. The interplay between paved surfaces, tree-covered areas of grasses and shrubs and a water feature means that the square not only fulfills its function as a high-traffic transit space, but – equipped with robust street furniture – also becomes an attractive place for waiting people, strollers and visitors to the restaurant. As the adjacent traffic areas are expected to become even hotter in the future, the station forecourt outside the movement areas will be covered with large-crowned, shady trees, which, in combination with the evaporative cooling effect of the fountain, promise a significant cooling effect. The roadway for the buses in the square area will be made of in-situ concrete with the same aggregates and the same color nuances as the pavement in order to ensure a consistent, uniform overall impression.
