The compact, square-shaped building blends in the row of existing buildings along the central pedestrian aisle of the Brandenburg Technical University in Cottbus. In the four-story building the functions are staggered and arranged from bottom to top according to their user frequency. The superordinated seminar roms are situated on the ground floor, the rooms for the professors with the corresponding seminar areas are arranged on the first and second floor and on the third floor the data center is located. Consequently the level of transparency of the facade is structured from the transparent ground floor to the completely closed top floor. Despite of their compactness the floor plans are organized in such a way, that corridor situations could be avoided and plenty of space for communication and views remains.
