Others are correct, it’s the infrastructure for the building that in warmer countries is generally in a basement. Most Russian buildings do not have basements unless they are government because of the cost in excavating and stabilizing it. Instead buildings especially in the very cold areas of Russia are on stilts and entry points are elevated above the average snowfall.
I see. So does that mean it’s a large windowless (ie dark) room that can be accessed from the central staircase? Have you ever been in/seen the entrance to it?
