There is no concrete plan, but the general idea is that the room has turned into a storage shed when it should really be a creativity/productivity friendly environment (assuming we find a way to keep it reasonably tidy) with lots of spacious surfaces and well-organized technologically advanced devices, err, stationery and stuff.
I don't know anything about insulation or the forest heating system, but I guess you have a point. Also, now that I think about it, there are no radiators in the room, right? Anyway, I'm sure we could find some incredibly cheap (or free) second-hand rugs with our amazing scavenging skills.
I'll go to the paint shop and check on that!
