Add more floors to my model ...

I imported the rest of my present house from the Floorplan drawing.

Here is the main floor, perched over the basement. The funny overhanging look is because I didn't do anything to show that there is actually any support for the house in the crawlspace, which is what is under the front part.

Here is a top view ... [The stairs are just blocked in as a box.]

Here is a view with the top floor on. It isn't very accurate because all the walls are shown as going up to head height, when the only outer walls that go up that far are the dormers. Also, again, the stairs are a box.

I don't know how much work I'll put into making this accurate. I mainly care about getting the parts that need to be worked on accurate & most of the existing house will stay as it is for now.
