How much did it cost? Was it a lot of upheaval? We would want to convert the rear half of ours in to a very small office. Possibly still with a door in to what remained of the garage where we would keep bikes etc. It would be nice to make a small window at the side. This would overlook the side of the neighbour but they have no windows at that side and it's just a path at the side of the house so I'm sure she wouldn't object. Just wondering if we'd get a room worth having for the cost?
