OK so I have wrestled with this house for waaaaaayyy too long. Still, the room over the room is fighting me. I think I am getting close.
This is an as-built design, with a new flat roof over a storage space in the garage to give the client stand up space in the storage room.
The house is complex and I have not even begun to work on the basement which has two floors. One of the floors contains a built-in swimming pool. That should be fun. There is a basement level under the garage as well.
The storage room over the garage has a crawl space on the right side of the room when viewed from the front of the house. I have included a couple of screenshots so that you can get an idea of where I am trying to go with this.
There are a few other problems that I am having with walls not stopping at intersections on interior surfaces and exterior surfaces as well.
