Ackerstraße 29, Berlin-Mitte
New construction of residential and office building
The new five-storey high residential building is part of a vivid and varied cultural area in Berlin’s Mitte district, impressively presenting itself with three open façades and a penthouse. The 1,000 square metre plot is adjacent to a green square dominated by a fountain with a stone sculpture by Ernst Wenck.
Square-edged but self-contained in shape the volume is emphasized by an elaborate façade design: beige bricks burnt in a circular kiln were chosen for the surface cladding together with a strongly graphical though irregular structure of massive elements of white architectural concrete. The windows in different sizes and upright as well as landscape formats are absorbing and reflecting the heterogeneous character of the neighbourhood.
The building comprises eight residential units with an area of between 70 and 190 square metres. The penthouse in the 290 square metres stacked storey is fully glazed and provides a circumjacent walk and a spacious terrace towards the south. Office and commercial spaces on the ground floor, the first floor as well as partly the basement ensure a good balance in terms of usage. In addition to commercial units there are ten parking lots in the basement.
The building is completed according to low energy standards. The units are furthermore provided with solar energy, as the entire roof area is equipped with a photovoltaic system. A geothermal system supplies the building with heating and air conditioning.

Technical details

The main structure of the building consists of a reinforced core and a mixed construction with load-bearing partition walls. A high flexibility of this construction allows use changes in future. The generous room height additionally ensures structural alterations without expensive changes in the shell construction.

The building is equipped with geothermal energy, which fully covers the heating and warm water demands. All spaces including the apartments are ventilated by a central ventilation system which guarantees an efficient heat recovery.

The façade claddings as well as the particular window surrounds made of architectural concrete are corresponding in a harmonious way with the material variety and scales of the adjacent community hall of the Elisabeth Church. Moreover this surface will age with dignity without regular intensive maintenance work.
