This is the current design but it does keep changing shape, colour and layout. The windows may be bought but we may get a local caftsman to make the frames and buy the sealed units.

The structure will be simple stud wall with an insulated floor, walls and a lot of insulation in the roof. this should mean that there will be a minimum need to heat the building as at the moment we only have electricity. If it is cold we may install a small wood stove.
