This project is to make CAD drawings 2D of three floor plans of our house with a possible extension + Front, back (only one floor above other buildings), left and right facades (now only Front exists. You should set out current m2 and m2 with extension. I've added a photo of house. The house has only windows to one side. In the current stairs there are glass bricks to the left, this should continue up. Also there should be glass bricks in part of wall to let light into new bathroom on second floor. (Current second floor is an attic with 1.50 m head room).
