Hello
I have built a double garage with a loft that I am now insulating.
Garage section walls 120+45 mm insulation
Garage section ceiling/floor structure 200 mm
Loft sloped ceiling 200 mm
The garage section is intended to be heated as needed and no cars will be driven in and out during the winter.
The loft consists of two rooms, a small office and a larger guest room. The guest room is to be heated as needed, but the office is to be constantly heated. (As long as I keep my current job)
Where should I place a vapor barrier? Does anyone have any ideas?
My original thought was to only put a vapor barrier in the office, but maybe I'll only work from home for 2 more years and then I don't want to keep the office heated!
Is it safer to have a vapor barrier or not? Biggest risk of damage?

I can't really see the point in using plastic in your case. Especially because there won't be any moisture addition to speak of, neither from showering or cooking, nor even human presence (exhaled air and sweat) to any great extent. I would skip the vapor barrier, I assess it as completely risk-free in the building you describe. That it won't be heated in the future is another argument against the plastic.
