I do know it is a bit late in the year, however the summerhouse is against our 2nd bedroom wall, it has been secured together by a carpenter. We couldn't get it assembled. I have sealed the windows with tape, had new batons put in, there is carpet on the floor, they have their old base and a box with blankets. There was no heating in the back room anyway and we havent had the heating on in the flat. I would obviously moniter the situation. They actually seem happier outside.
