The building erected after the war left an empty spot on this corner site in the much asked for housing borrow of Berlin Moabit. The new construction fills this gap and "grows" over the 1950th building on the upper floors. To enhance the floor area the façade pushes into the street and the staircase moves towards the courtyard as an open structure. The filigree metal structure of the staircase wraps along the existing building façade on the courtyard and provides every flat (new and existing) with south facing balconies.

On the inside the building geometry generates exiting floor plans for 12 rental apartments between 50 to 120 m². A living, dining and cooking space connects north with south façade and enables generous vistas. Via sliding doors studies can be added, enlarging the loft character of the flats. The two roof levels accommodate 6 Maisonette flats. Here the living, dining and cooking area is one double height space orientated entirely to the south. All apartments are equipped with a laundry/utility room and a bathroom directly accessible from the master bedrooms.
