The architecture pursues a calm architectural language to the outside towards Franklinstraße and to the south towards the neighbors with materials corresponding to the surroundings, and a lively, crystalline spatial and formal language with generous glazing to the inside. There, open areas, loggias and visual references to the Spree are integrally planned. The steps of the blocks are planned as usable, generously greened roof terraces.
For a high degree of flexibility of the building, the floors can each be divided into generous utilisation units. Due to the materiality of the brick, the building appears to the outside as a massive and monolithic structure. The design is characterized in the facade by a very clear recurring profiling of the building body through the projections and recesses of the windows. Like a constant pattern, these alternate in a grid of 10.80m around the building. Inside, this massive, monolithic attitude is countered by a lightness and transparency with a multitude of visual connections. This lends the common rooms a maximum of quality and gives all interior areas a reference to the greened inner courtyard and the Spree riverbank zone.
The four foyers, the café and the commercial areas on the first floor open onto the green inner courtyard and have a direct link to the banks of the Spree in the east.
The first floor in the courtyard is designed as a plinth floor with floor-to-ceiling glazing and clinkered areas and thus contrasts with the glazed facade above in its materiality and design.
