Pre-revolutionary series

 Construction of such buildings continued until 1920.

These were 1 to 4-storey houses with one and rarely two entrance halls.

Apartments had mainly 4 to 6 rooms, sometimes 1 or 2. There were one or two apartments, rarely three or four, per storey.

Additional information: Walls are made of red brick, houses were of landmark nature. At first, wooden floors and after 1905 mixed-type floors were used. Armoured concrete floors were used during the reconstruction.

Houses were designed in Art Nouveau style with outer stuccowork. They were very large, robust and solid. There were no rubbish chutes. Elevators were installed rarely after major maintenance.
