The mesh topology looks good. Being that it wasn't made by conventional means I was wondering if the poly count was getting out of hand. It's a little tough to tell from the attached pics but it seems that there is a good amount of polys present on the ogee moulding parts (doors, windows, etc) which there would be moldeing by any app, but that might be something to keep in mind. Not that a rooms poly count is going to make someones computer crawl but maybe being able to adjust how many lines equal "x" amount of curve...kind of like being able to select high or low poly (kind of like we modelers create either high or low poly meshes).
If it's 1 of 20 houses, would probably wany low poly. If it's the only house, probably would want high poly.
Just something to consider...or toss in the round file.
