Hi, I don't want to hassle any builders yet as I am busy saving to get a room built over our garage and our attic converted at the same time as the roof would have to be extended anyway. Would anyone have any idea roughly how much this would cost so I know how much to save? or how much a room over a garage would cost to be done alone? as I know prices have come down in the past couple of years. Standard size garage, at the moment a 3 bed semi detached house. thanks M
