The kommunalka — the communal apartment — is St Petersburg's most characteristic form of housing: a city of grand tenement houses was the first to be "densified" after the revolution, and it is still un-densifying today, slower than anywhere else. Behind the ceremonial facades of the centre hide apartments of five, ten, even twenty rooms with one shared kitchen — not a museum relic but the living daily arrangement of thousands of residents. Here's where kommunalkas came from, what a real one looks like — and whether a visitor can see one from the inside without crossing anyone's boundaries.

Where they came from

Before the revolution, central St Petersburg was built up with income houses: wealthy families rented enormous ten-to-fifteen-room apartments — with studies, servants' quarters and enfilades of connecting rooms. After 1917 these apartments were "densified": one family per room, kitchen and bathroom shared by all. Thus was born the genre in which half the city grew up — along with a good half of Petersburg literature and cinema.

What a real one looks like

Can you get inside?

Feeling the genre from the street

Start around Five Corners, Vladimirsky Prospekt and the lines of Vasilyevsky Island: count the doorbells by the doors, study the windows of former enfilades, peek into open courtyards. The courtyards deserve their own chapter — the famous well-like courtyards of St Petersburg are the outer face of the same world, and much easier to visit.

The kommunalka is not an attraction but the living fabric of the city — and that is its power: here St Petersburg isn't performing. Look with respect, and the city will show you more than any museum.
