Exactly what is on the other side of the three walls? Are they open to air, outside or another room, or back-filled with earth etc?

Concrete has a thermal conductivity similar to glass

W/(m K)

Concrete, dense 1.0 - 1.8
Glass, window 0.96
Plaster light 0.2
Cork, re-granulated 0.044
Styrofoam 0.033


I think you really need to make the small space sacrifice and get something on those walls, or be prepared to keep the heater running.

You'll need to do yourself a favor too with acoustics.
