The Moringa project in Hamburg's HafenCity will not only be the city’s healthiest high-rise building, but also the first Cradle to Cradle residential building in Germany. Together, Drees & Sommer and EPEA GmbH experts are providing a wide range of services for the landmark project.

Moringa is being developed as a pilot project by Landmarken AG, a leading project developer, in partnership with the architectural firm kadawittfeldarchitektur. One of the special features of the residential tower is that at least 50 percent of the building should consist of recyclable materials. All other building products are also tested and optimized for their sustainability and impact on health and the environment. In addition, the planning provides for as many green spaces on and around the building as the property will cover when the land is built on. These areas will provide clean air and transform the building into a green oasis.

The project also focuses on social aspects in addition to the ecological factors. This is because subsidized housing construction makes up around 30 percent of the apartments being built. In this way, Moringa brings together sustainable construction and affordable living in a unique way. The diverse mix of apartments is complemented by co-working space, food and beverage outlets and a children’s day-care center. The building comprises a total of just over 20,000 square meters of gross floor area.
