Hi

One thing I am concerned about is ventilation, which can, and sometimes can't, be a good thing. Having a vapour barrier prevents the ingress of moisture but I wonder how moisture say from breathing out is expelled. If having an extractor fan, you still need an opening for it to work ie a flow of air from outside to inside and to the outside but then it's going to let in the moist air, a catch 22 situation.
I can see the real gain from having a dehumidifier which is probably of greater importance than heating though the two combined would be of overall benefit. I guess the opening wooden window frames won't exactly be gas tight so would allow for natural ventilation. Obvious I know, but keeping an eye on the outside humidity is very important to avoid damp air into the working space.

Regards
Symon
