Bolshoy Prospekt P.S., 39, apt. 8, Saint Petersburg, Russia, 197198
The house was built for professors of the Medical Institute. It was equipped with an elevator (from the level of the 2nd floor (residential)), plumbing, electric lighting, a coal boiler room with a highly efficient steam heating system. The building had a garbage chute, installed on the service staircase in a wall niche, with a chain conveyor on the 1st floor to transfer garbage to a garbage storage area in the yard. The storage area had a lifting floor with a mechanical hoist for unloading garbage into a cart. Each apartment had a large stove (2 x 1.5 m) with a small firebox for peat and coal briquettes. There were bathtubs with water heaters (type "Titan"), with fireboxes for the same briquettes. After densification, many apartments were fitted with round wood-burning stoves, the elevator did not operate (until the 1970s), the garbage chute was bricked up, and food was cooked on primuses, kerosene stoves, etc., until gas stoves were installed in 1952. A laundry room with spaces for drying clothes was arranged in the attic. The house was quite comfortable even by today's standards.
