I currently have a 3m x 3.5m traditional, I think Georgian style conservatory in a south west facing garden. It has dwarf walls, lots of draughts between roof and walls and is freezing cold in the winter and unusably hot in the summer. To get better use from the space, I'm thinking about getting a builder in to convert it into a more normal room. I'm thinking of reusing the existing double glazed double French doors to the garden and some of the existing windows, then adding brick walls/columns to take the weight of a tiled roof and all the hardware that goes with it. Would this be a reasonably straightforward job to do? And would I need to persue any permissions? There is planning for the conservatory already. Can anyone see any reasons that this would be hard to do? It's just a thought at the moment and am looking for views or experiences before trying to find quotes for the work involved.
