The combination of kitchens and living rooms into a single space was practically the most popular change. But this option is not possible in every apartment, since in brick houses built in the 90s of the last century, these premises are shared by the supporting wall. Therefore, the only thing that the inhabitants of these houses can afford is a specially fortified doorway. The inhabitants of the buildings of Stalin’s times have a great advantage in this regard — these houses are built in such a way that when redevelopment, you can demolish all the walls in the room, thus turning an apartment into such a fashionable studio today.
