I wonder if anybody could advise on the best way to convert and insulate a single brick external coal house . The roof is made of wood and has felt over the top . I’m planning on fitting the washer and a vented dryer in there along with a Sink . I’ve heard of king span , insulating plaster board etc etc .....abit unsure really of the best plan of attack. Any ideas and help would be appreciated.
