Hovis builds a garden office*

Yeah I believe that. The glazing in our kitchen is south facing and the room become unbearable rather quickly. On the flipside, this is north facing so only sees sun late evening. We'll see. I'll put a unit in if I need to but don't want to pay for one now and discover that I didn't really need it later. I do have a electrical circuit put in dedicated for heating which will be left unconnected initially so I can use that should the day come.
