The authors of the A4 apartment building project are architects Martin and Viktor Rudiš. The building of collective garages is connected to the residential house A4 on two sides. The roof is made as a green area with artificial irrigation during the growing season. There are 38 garage spaces in the building. Fenced front gardens are partly located on the roof area of the collective garages and the remaining area is public. The construction of the A4 apartment building with a parking garage was completed in 2001.
