It is a dual purpose shed .... the bit you see is my summerhouse where I can sit and watch the birds and work on my genealogy (via wireless router from the house). The glazed doors all fold back for when the sun shines and I have a heater in there so I can use it all year round. Hidden at the back is himself's workshop.
We started off intending just to add a sort of leanto conservatory on the front of our old shed - but when that fell down during the start of construction (I leaned on it!) we started from scratch with a new concrete base. The outside is covered in featherboard, all the walls and roof are insulated and the inside is tongue and groove. Although I did quite a few of the minor jobs, the REAL builder was our mate Bill.
