One of the main features of Khrushchev-era apartments, as is well known, is a small kitchen.
You will be surprised, but this layout was not invented by Soviet architects.
Why do Khrushchev-era apartments have small kitchens?
This layout was not an invention of Soviet architects, but of the pioneer of architectural functionalism, Le Corbusier.
The famous French architect considered houses to be "machines for living" and was an advocate of people eating out.
The houses he designed included dining rooms, laundries, hairdressers, etc.
In the Soviet Union, where the catering industry was actively developing, Le Corbusier’s ideas were well received.
It was assumed that citizens would eat in canteens, and they would simply not need large kitchens.
