unfortunately so, but the shed is quite well insulated and it seems to be working ok so far... but the assembly of most guitars will probably still happen on the dining room table, and we have cleared out some of the cupboard space in the house. so all my wiring and set-up set up stuff can be kept indoors as well as any nearly complete guitars. i do have to be more aware of the space i have available than before..
I actually forgot how big my spare bedroom was till i had moved two workbenches and years of offcuts out of it ;)
it will have to do till i can afford to move house
