On the 464 m² corner site between Greifswalder Strasse and Heinrich-Roller-Strasse in the Berlin district of Pankow, Prenzlauer Berg, an office building was created whose expressive, lively main façade with its floor-to-ceiling, square grid structure of light architectural concrete prefabricated parts immediately strikes the eye.

The structure comprises six full storeys, which can be used per rental unit as flexible combinations of open-plan offices, individual offices, conference and meeting rooms as well as coworking spaces. On the ground floor there is an office unit with meeting areas and open-space workplaces. The top floor is set back by approx. 1.60 m on the street side. The roof area, which is accessed via the 5th floor, is greened and partly designed as a roof terrace. The basement is intended for parking spaces for cars, bicycles and technical rooms.

The new building, which is used as a modern office business centre, follows the line of the building on the street side and connects to the fire walls of the neighbouring buildings while maintaining the spacing in the courtyard and exploiting the maximum building depth. All new building parts have flat roofs.

The street façade on the ground floor consists of large-format insulating glazing in mullion-transom construction. From the first to the fourth upper floor, the façade is constructed in a square grid of architectural concrete. The slightly twisted pillars and floor slab strips meet alternately at either a high or low point and form a coherent, dynamic, organic-flowing structure. At the high points of the grid structure, the façade protrudes 50 cm above the building line. The inner courtyard facades were realized as plaster façades with circumferential window bands with metal railings. The roof area with its restrained glass façade forms the clear, calm end of the building.

The representative foyer of the main entrance is accessed from Heinrich-Roller-Strasse. As a special design element, the lighting is integrated into the ceiling, backlit showcases in the walls are intended for the exhibition of works of art.
