04 | 2024 Award
We were speechless when we received this great news! We won bronze in this year's Competitionline Ranking! GTL won a total of 23 competitions last year, an incredible success for the whole team!
We believe that the expansion of our management team has played a key role in this success. "We can discuss things more intensively and delve deeper into the competitions. At the same time, our interdisciplinary design team is a great asset. "The mix of experienced professionals and young talent is also the secret of our success. This is how we promote innovation and secure our young talent at the same time."
We would like to take this opportunity to say a big thank you to everyone involved! Without the outstanding work, creativity and passion of the competition team, this achievement would not be possible!

Landscape architecture - Outstanding projects 2025

The redesign of the approx. 9000 m2 harbour area has not only reconnected the harbour to the Weser, but has also improved the quality of life in the historic town centre of Bad Karlshafen.

Nomination for the German Landscape Architecture Award 2025
With our project for the old Bonames airfield in Frankfurt am Main, we have been nominated for the German Landscape Architecture Award 2025 in the category ‘Maturity Test - Projects, 20 years and older’!
The expert judges nominated a total of 35 projects out of 140 entries, which can now continue to hope for the coveted awards in nine categories. We are delighted about this recognition and are looking forward to the final decision on 11 April 2025!
The old Bonames airfield is a prime example of the sustainable transformation of a historically characterised area into a valuable natural and recreational space. For over 20 years, the site has been developing into a nature park through the natural process of succession, combining landscape, history and urban greenery in a special way!
