Hello,
we moved into the 70's detached house recently and when the winter came we noticed that some of the rooms are surprisingly cold, especially the kitchen. I had a peak under the plinths of kitchen cabinets and noticed a hole in the corner which seems to be only in the internal wall, and not through.
Anyone knows whether this hole has any purpose or can it be plugged, and if yes what would be the best way to seal it?
