Dollhouse Puzzle (Attic)

Hint 1 of 8:

Check the rules section -- the rules are pretty complicated here.

Hint 2 of 8:

There are two things you can do for the bottom section of the house: use
trial and error or read on for an answer.  You can probably think out your
solution, but I doubt it would be worth it.

Hint 3 of 8:

Try setting a round window to up, semicircular to right, rounded rectangle
to down, and a complete rectangle to left.

Hint 4 of 8:

You can do this by starting from the 6th window from the left on the bottom.
