On a site of 10 hectares in Berlin Mitte a new building with a gross floor area of approx. 260,000 sqm will be built to accommodate 4000 employees of the Federal Intelligence Service. The main task of the competition was to develop a concept strong enough to take into account all the constraints of the urban context as well as the technical and organisational requirements of the Intelligence Service. With a height of approx. 30 metres, the main building is located in the centre of the site.
