Four years ago, and even more residents at home, where my parents live decided that the entrance and staircases look completely uncomfortable, having consistent and attaching how much money from the nose of money, they ventured such a step.
UPD: Mom just asked, speaks 600 rubles from the apartment (2 apartments just did not surrender from the entire entrance).
In general, see what happened. Drawings made a grandmother living on the third floor.
Tulle on each of the 9th floors.
All good and clean, cozy homes!
