version 3, calculated correct dimensions for a regular octagon and changed the way I drew it slightly, the roof still isn't perfect but now the same roof section doesn't quite fit all of it
Also got some better textures and did a bit more decorating, but ran out of inspiration for a couple of rooms. Ah, and I see I left one patio door in the wrong place. Can't select a wall section without moving it, as it covers the entire section on the plan.
