Monheimer Tor, Monheim

Topping-out ceremony

The existing shopping center in Monheim, the Monheimer Tor, is supplemented and enlarged by an extensive new building. GTL is responsible for the planning of the roof and interior greening. On 21.01.2022 the new building was inaugurated by a public topping-out ceremony.

During a speech, among others by the building owner, the topping-out tree was raised and the building was then consecrated with the traditional topping-out ceremony by the carpenter. This celebration marks a successfully completed milestone on the road to completion in 2024. ©GTL

With the new building of the day care centre, another educational and social facility is integrated into the existing urban situation of the city. A spacious forecourt including parking spaces forms the entrance area and offers enough space for daily exchange among parents or for events of the KITA. Various climbing and balancing facilities, a covered sand playground and other play and retreat facilities create a sensory stimulating play experience for all age groups. A separate movement area for the crèche contains further play and learning elements for toddlers. The outdoor space is complemented by beds for all children to sow and harvest their own crops. The generously planned terrace also offers the opportunity to taste delicious fruits and herbs from the snack garden.

 

Large contiguous green spaces, green roofs and terraces throughout, and a few paved areas create an overall concept that is close to nature and blends sensitively into the existing green space. Offsets in the cubature of the building figure and the resulting interior layout create clear allocations and zoning in the open space:

A spacious forecourt, which integrates the turning loop including parking spaces into the design, leaves plenty of space for daily exchange among parents and offers an ideal place for occasional KITA events. A linear play sculpture (which also integrates the wood workshop and the tool shed, among other things) offers a play experience that stimulates all the senses for all age groups, from various climbing and balancing opportunities, a covered sand playground to retreat and cuddle boxes. At the same time, the movement areas of the KIGA and KRIPPE are spatially separated as a matter of course.  The outdoor area for the CRIPPER groups can be separated from the rest of the play area by low wooden gates if necessary and will have its own sandbox with deck and playhouse and a small grassy hill with a toddler slide. Enough space remains that further play facilities could be arranged. Beds for sowing and harvesting are provided for both age groups.  The terrace at the dining area is embedded in a snack garden with a rich offer of delicious fruits and herbs and screened from the rest of the grounds by low fruit hedges. In the rest of the grounds, too, the shrub borders are enriched with strawberries, blueberries and mint; all shrubs and trees are fruiting and/or suppliers of craft materials such as nut and fruit trees or chestnuts. The green corridor running in a north-south direction with trees worth preserving is completely preserved.

The high-rise integrates into the block-like structure and serves as a residential and office building with a variety of ground floor uses. The open spaces consist of a lit inner courtyard in the foyer and a publicly accessible green plaza.

The urban development concept envisages two compact solitaires on the two plots – together with the adjacent buildings they form an ensemble with a spatially clearly defined “green plaza”. The ground floor is intended for public use. A foyer at the corner of Ollenhauerstrasse and the future plaza marks an open entrance. A green inner courtyard in the foyer on the ground floor is thus invitingly perceptible into the urban space. Smaller commercial uses, restaurants, cafés, bakeries and fitness studios are proposed uses on the ground floor, which could also be laundromats or to-go markets depending on the tenancy. The flats will have balconies and can be designed as 2- to 4-room flats (at the corners of the building). Due to the noise emission on Oscar-Romero-Allee, the residential use should be realised in the part of the building facing the plaza. Thus, half of the high-rise building would be office and the other half residential. This makes sense because of the address formation, development, facade structure and the shaft layout.

The urban setting creates a strongly greened outdoor space that offers an attractive place to spend time outdoors, even if the first building block is realised exclusively. The continuous carpet of large-format, finely nuanced gray-beige slabs is structured by planting areas in such a way that the access area and areas for outdoor catering are kept generously open. At the same time, quiet and sheltered lounging areas are created without the need for consumption, taking into account all walkways and potential pedestrian shortcuts. The lush, low-maintenance grass/shrub plantings display a continuous, changing flush of flowers throughout the year. They are somewhat lowered to provide retention space in the event of flooding and also absorb normal precipitation so that rainwater only has to be discharged into the sewage system in exceptional cases via the raised inlets. All access roads, delivery and fire brigade parking areas can easily be integrated into the open space concept. For a short break in between or a longer stay outside, benches with and without backrests are arranged along the planting beds, partly across the corner. Loosely arranged sophores show their creamy white blossoms in June, when no other trees are in flower, and amber trees with their scarlet autumn foliage are placed in such a way that both shady and sunlit areas are created.

The new building ensemble consisting of a day-care centre and a three-field sports hall plays a special role in the Zollhafen district, which is otherwise dominated by residential and commercial areas. The new building parts occupy the site mainly as single-storey buildings. The day care centre has a multipurpose room on the upper floor with a terrace in front. As a contrast to an urban environment in which children grow up in multi-storey residential buildings, all groups receive their own small ‘house’ with a direct ground-floor connection to the outdoor space, which, in addition to play areas for all, also offers smaller, sheltered and covered spaces. The three-court sports hall is buried by one storey to attractively interweave the activities inside with the surrounding urban space via the glass façade. The optional padel court is located at the northern tip of the site. Farm bike parking is located along the building to the east and south.

The overall open space planning concept aims to create differentiated schoolyard areas with different characters, atmospheres and functions in order to provide pupils of all ages with a diverse and appealing range of uses.
The urban positioning of the new buildings creates a flowing open space structure, three open spaces with different characters and identities along a connecting promenade. In the southern area of the existing building, a green, rather introverted open space is created with a learning and play landscape that integrates the existing trees and supplements them with new plantings, thus translating the theme of the Kaiser Wilhelm Park to the south into the schoolyard. In the central area of the site, between the new and old school buildings, the sports hall and Stankeitstrasse, an open, multifunctional square area is being created, which also forms the main access to the school for bicycle and pedestrian traffic in an appropriate gesture. In the northern area between the sports hall and the clubhouse, the focus is on functional sports fields. In addition, the Kiss & Ride zone and underground car park access are located in this area, coming from Waisenstraße, which ensures conflict-free access to the site.

Ein Pflasterteppich aus Betonstein mit wasserdurchlässigen Fugen bildet die Grundlage im Kontext der Materialität des Schulhofes. Flächen aus Wassergebundener Wegedecke in Kombination mit üppigen Pflanzflächen und Baumpflanzungen bilden Bereiche mit Aufenthaltsqualität und besonderem Mikroklima. Zudem besitzen sie die Funktion als Entwässerungsflächen, die anfallendes Regenwasser aufnehmen, speichern und versickern können.

Der Freiraum rund um das Vereinsheim erhält einen grünen Charakter. Im östlichen Bereich wird der Baumbestand erhalten und es werden Spiel- und Aktivitätsangebote geschaffen. Rasenstufen im Böschungsbereich bilden Aufenthaltsqualität im Kontext des Sportplatzes aus und fangen den Höhenunterschied ab.

Natural integration and gradual development

The special island location of the area, embedded in neighbouring landscapes with forests and valuable biotopes, requires a careful and flexible development strategy. This must react responsibly to the different ecological and social requirements. The aim is to protect the natural environment and at the same time offer the opportunity to adapt to the dynamic requirements of the surroundings.

A key objective of the planning is to clearly define the edges of the area in order to create a clear settlement boundary to the neighbouring landscape. This is essential in order to preserve and protect important green spaces and ecological connections in the long term.

The commercial area

The commercial area is understood as a programmatic unit that integrates a variety of plot sizes and utilisation profiles. This enables the establishment of high-quality industry, service companies, research facilities and science. The flexible utilisation is intended to create an attractive location that meets different economic requirements.

In the area known as the LEA, the listed buildings will be retained. This will be supplemented by two separate residential buildings that will be carefully integrated into the existing ensemble. This approach preserves the historical character and at the same time allows for a gentle further development of the area.

Thematic areas and different utilisation structures will be created within the commercial area. This allows for flexible marketing that is geared towards the specific needs of potential tenants and users. Both small-scale and large-scale developments can be realised.

Plot sizes and development dynamics

The development of the business park allows for flexible development with variable plot sizes, ranging from small (S) to medium (M) to large (L) and very large (XL). This offers space for different types of business, from low to high buildings, and enables dynamic adaptation to demand.

Development and networking

The new main development of the area will be largely retained. By maintaining the existing infrastructure, better property layouts are made possible. A central, green main square serves as a multifunctional meeting point and centrepiece of the area. This square forms the entrance and gives the area an inviting atmosphere.

Two mobility hubs not only serve as collection points for parking and sharing services, but also as places for communal and catering facilities. On the ground floor of these hubs, for example, bakeries, kiosks and small shops are planned to serve the area’s residents and workers.

The industrial estate’s road network will be closely linked to the surrounding roads. These include access to the S-Bahn station, cycle paths and a bridge over the neighbouring main road. This will ensure optimum accessibility for various road users.

Blue-green infrastructure and sustainability

All squares and streets in the industrial estate follow the principle of the sponge city. Care is taken to maintain the highest possible proportion of unsealed surfaces. Where possible, sealed surfaces will be equipped with infiltration-capable surfaces. Rainwater is channelled into open gutters and troughs where it can seep away and evaporate. Excess water is channelled into large retention areas to ensure efficient infiltration in the area.

All roofs in the area will be designed as green and retention roofs and equipped with photovoltaic systems. This will help to retain rainwater for as long as possible and generate sustainable energy at the same time.

The entire neighbourhood is characterised by changeable, flexible and yet durable structures. High-quality building materials are used that are recyclable and CO2-neutral. The aim is to achieve DGNB certification, which emphasises the sustainability and environmental friendliness of the project.

 

Gradual development and initial projects

The industrial estate will be developed successively from north-west to south-east. However, actual demand will also play a decisive role in the development process. The start-up centre at the Entrée, the innovation centre at Quartiersplatz and the existing leisure centre will serve as the initial spark, giving the starting signal for further development.

Interlocking landscape and building

The new building for Cadolzburg Grammar School is an ensemble of three staggered structures that fit into the topography of the site and, in conjunction with the sensitive integration of the sports hall, dovetail with the landscape. The new main access to the school is planned towards the south. Here, the grammar school formulates its representative address for arrivals through a forecourt that leads via the main entrance into the communicative heart of the school. From here, there is a further interlocking with the embedding of the green break areas in the eastern area. By embedding the sports hall in the overall ensemble, its roof area can be used as an extended play and leisure area during the breaks. The sports hall will have its own prestigious entrance in the western section of the access road. Towards the north, it will have a panoramic window from which the area of the well-organised outdoor sports areas can be viewed via the grandstand.

 

 

 

Outdoor facilities

The start of the new school day takes place on the forecourt. Planted with a multi-stemmed, generously planted amber tree, with its round bench hovering around the tree, the entrance plaza is both a passageway and a recreation area.

We see the open space directly adjacent to the assembly hall as a heavily planted 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 central recreation areas are paved with concrete paving that is suitable for seepage, with linear grass paving at the edges. The furnishing elements are designed to be multifunctional – the chill deck, located near the hall, becomes a stage during events. The sunken seating area, which is orientated both inwards and outwards, is a meeting place for breaks as well as an outdoor classroom. The school garden, enclosed by a low hedge, also offers space for a lesson in the fresh air. A bird protection planting with native trees, shrubs and a border of native wild herbs forms the end of the agricultural landscape to the east. In areas where there is no need for a lawn that can be played on and walked on, lean, double-cut meadows contribute to biodiversity.

Movement landscape
On the roof of the gymnasium, the school landscape becomes an exercise landscape. From a boulder sculpture to a streetball court, callisthenics and obstacle courses to floor trampolines, there is everything you need to combine sport and fun. It goes without saying that you can also just watch from time to time: Long benches where you can sit together on the backrest and more intimate seating shells for two form the “grandstand” for the action on the pitch. The areas are framed by a free-flowing, drought-resistant planting of grasses and shrubs. They are positioned in such a way that the loads are transferred as efficiently as possible to the edges.

Sports areas
For the sports areas, the existing, sloping topography is levelled out in such a way that the amount of soil added and removed is roughly balanced. Due to the chosen positioning of the school building and its arrangement, all the required sports fields can be arranged outside the 20 m zone towards the forest.

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. 20-40cm 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 topography and also collected in cisterns for service water use. In the event of heavy rainfall, excess rainwater is channelled into trough infiltration systems (infiltration cascade) between the sports fields and the neighbouring forest.

In addition to aesthetic considerations, all plantings are carried out in such a way that they 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.
