Here are some pics of progress so far. The roof still is n't quite right, I may try it again, I suspect one or another dimension is subtly wrong, meaning the sections don't quite join correctly.
later I'l play with some rendered interior shots, but for now sc5reengrabs from the 3D viewer...
I ;ove your two floors, but my mom already has a regular rectangular house and I want to built my octagon house on top of hers, do you think that will look good?
