Sauerbruch Hutton became the winner in competition on building of a new building for Office for Urban Development and Environment. The building is planned to construct by 2013.

The project represents a complex of buildings and a tower where public zones (restaurants and showrooms) will be placed. In the central lobby city models of Hamburg which can be examined through a glass facade will be exposed.

In a building passive and active measures, for example, thermal isolation, cross-country-ventilation, the system of heating using a solar energy, the geothermal equipment are combined.
