Within a unified landscape concept the plan provides urban linkages between the surrounding streets and a succession of varied urban spaces within the area. Like the prototypes we know from history one experiences between Kurfürstendamm to the Kantstrasse a glass covered Passage, which leads at midpoint to a large Gate, the entry to the Loggia and The Court, surrounded by the new and existing buildings with a large Voliere as centerpiece. From this court, 2 Gates lead to the Kant- and Jochaminsthaler Strasse. Retailers and Restaurants along those routes further urban activity and intertwine public and private space.

The building configuration responds in plan to the angular characteristics of the City grid and mediates in volume and height between the existing building substance, the typical Berlin Block height and the tower slab. This block-datum extends across the project through canopies, projecting wings, glass roofs and changes in the facades. The triangular glass enclosed point at the entry to the passage becomes a “City Sign”, enhanced by a light sculpture of Yann Kersale. In a changing display of colors from red to blue to white the triangular room assumes different stages between materiality and immateriality between day and night and establishes a counter point to the commercial signage surrounding the block.

The constructional and technical concept is simple and uses a series of components. The concrete frame is left exposed and clad in a double glazed glass and stainless steel facade, with load bearing glass mullions. All services and air are distributed in a raised floor. This air displacement system floor is assisted at the facade with a ceiling mounted cooling and heating panel. Suspended lights give a mixture of indirect and direct light. Demountable partitions create a flexible office environment. A computer controlled building management system allows for central and decentral control of lights, temperature, sunshades and windows. The building can thus adapt to the exterior conditions with respect to the desired interior environment.
