Square in base (33 meters long) and the main facade characterized by square grids (16.5 meters high), adding up exactly the ratio 1:0.5. All four sides of the house were designed differently. The west facade, which faces the square, is dominated by the skeleton grids, creating open loggias in front of the facade. On the top floor, the rooms in the central part are replaced by loggias without a roof, ensuring that the central hall inside can be illuminated with daylight via a skylight.
The house demonstrates the connection between inside and outside and its transitions, one typical feature of modern architecture. Furthermore it shows its basic construction made of a concrete skelton. The other facades of the house were provided with different window formats. The facade was clad in white marble. Inside the house is designed an atrium that represented a kind of hall of fame. The construction of concrete skeletons is also visible inside. The offices are arranged around this atrium. For staging purposes it was probably possible to open all 16 entrance doors at the same time.
