The Sims 3: fourth draft of our house (Part One) - basement, stairs and windows

The issue of the basement wall coming up through the first floor didn't seem like anything I could fix, so I've started yet a fourth version. I checked and made sure it didn't have that same problem. Also, as a consequence, where the upper and lower walls meet, there isn't that little bit of janky overlap, either. I even seem to have improved the stairs going to the basement, in that there is no longer a full tile's gap between the two sections I have to install to have a full flight of stairs. Once I felt secure that I had a better model to work with, I saved and left it again for a bit.
