It’s showing the whole house (minus the no-longer-existing second floor, I guess). The problem is that it doesn’t have lines pointing out the cubicula, even though at least some of them would be visible if there were roof cutaways for them.
Edit: in fact, that room between the “atrium and pool” callout and the “shrine” callout is apparently a cubiculum, but they couldn’t be bothered to label it!

To be fair, i don’t know anyone that bothers about running around labeling cubiculums.
