Situation in HafenCity Hamburg

#New construction of a sustainable residential block in HafenCity Hamburg

The first residential high rise built according to the cradle-to-cradle principle offers green spaces in and around the building for the recreation of residents, and improves the air quality and biodiversity within the entire quarter.

An ensemble of three buildings arranged around a green central courtyard is being developed on the northern bank of Baaken Harbour in the Elbbrücken Quarter of HafenCity Hamburg. Based on the cradle-to-cradle principle, the building is being assembled with recyclable and non-toxic materials that can be dismantled separately and reused at the end of the life cycle. All in all, the area created by horizontal and vertical greenery is larger than the building’s footprint. The green facade cools and conditions the air, produces oxygen and contributes towards the biodiversity in the city, characterises the residents’ urban realm and enhances the building’s design. In addition to being used as retention space and generate renewable energy, the horizontal areas are intended as exterior zones for private and communal use, for recreational purposes, urban farming, working and communication. The purely tenant-occupied property with variable floor plans and one third subsidized units is designed to accommodate people from different social backgrounds. The building incorporates co-living and co-working space, communal areas, such as kitchens, a library, a cinema, multi-purpose rooms, which can be booked via an app, a children’s day-care centre and a variety of exterior space on terraces, balconies and in the courtyard.

30% of the 70 car parking spaces in the underground car park are reserved for car sharing vehicles, and there are three times as many bicycle parking spaces. The mobility sharing concept, which includes a good selection of cargo bicycles, e-bikes and e-cars, is designed to support sustainable travel.

The design is based on analyses which reach far beyond the actual building, considering the inner city air quality, the consumption of land, rental prices, household sizes, communality and social isolation
