My neighbours wall ( a bungalow) is built up the the boundary line.
My garage is attached to this wall and the bungalow wall forms one of the garage walls.
I want to build above and behind the garage creating a bedroom above the garage and a two storey extension behind the garage. How do I build right up to the bungalow wall? (I don't want a gap)
I need to get the foundations close to the bungalow foundations otherwise I will end up with a gap and nothing more that a very think room.
