Ramboll Studio Dreiseitl are responsible for the waterscape on Potsdamer Platz in Berlin. Water was central to Renzo Piano and Christoph Kohlbecker's original design, but it was Ramboll Studio Dreiseitl that conceived and developed the scheme for rainwater recycling and created the many opportunities for public engagement with water. The scheme is one of the largest urban rainwater harvesting projects in the world and in 2011, it became one of the first city quarters to be retrospectively awarded the DGNB Certificate of the German Sustainable Building Council (DGNB) in silver.
Another major project in Germany is Arkadien Winnenden, the ecological city design which was named winner of the Green Dot Award ‘Build’ category in 2011. The firm turned the abandoned factory site into an eco-friendly development which combines dense layout with green space, includes permeable paving and waterways which provide natural flood control and a lake which filters rainwater.
In 2018, Ramboll Studio Dreiseitl was awarded the German Design Award in the category "Urban Space an Infrastructure" for their design and planning of the project Hafen Offenbach in Offenbach am Main, Germany. Studio Dreiseitl has transformed the initial urban plan by reconnecting public open spaces with their scenic context, creating a liveable as well as ecologically enriching neighbourhood.
In Asia, projects include the blue green infrastructure in the Tianjin Cultural Park near Beijing and the water strategy for the central catchment for the city of Singapore, together with the engineers CH2M Hill, as well as the design of the 60ha Bishan-Ang Mo Kio Park. The rehabilitation of the previously concreted Kallang River (which became a dangerous torrent in the rainy season) employed techniques of water collection and flood control which were entirely new to Singapore. Ramboll Studio Dreiseitl built a test area and held workshops to explain the concepts. The designers gave the river gentle banks and recycled the concrete from the old drainage channel to create stairs. Now Bishan Park is one of the most popular parks in Singapore, where people can have a new and direct connection to nature. In 2012, the design was awarded the Presidents Design Award Singapore and the World Architecture Festival “Landscape of the Year”.
