History
The building was commissioned by the housing cooperative of Wspólny Dach. It was designed by architect Marek Leykam in modernist style, and was built between 1962 and 1963. The building was originally built with its south and north walls having elevation consisting fully of glass windows which reached from floors to ceilings. The glass walls were hold by concrete V-shaped s, one on each sides. The high-rise also had lift shafts partially covered in glass, through which were visible the loggias. In the building were located apartments and a library. It was also planned to place a revolving restaurant at the roof, which was never realized. The reminder of such plans is a concrete circle at the top of the building.

The glass elevation was badly isolated, causing the apartments to get very hot in the summers, and very cold in the winters. Many inhabitants also complained about lack of privacy. As such, in 1973 the glass elevation was replaced by brick walls and two-times smaller windows. The characteristic V-shaped concrete supporters at the base of the building, and the windows of lift shafts, were also removed.

In the 1990s, on the roof of the building was placed a turret clock and neon sign advertising Jubiler store.

Originally, the building was designed and built with aforementioned elevations fully covered in glass windows, which extended from floors to ceilings.
