I once visited a friend in high school, and his home had a similar layout. I only saw a portion of it though. But they had a really nice garden in the back courtyard.

You can do a ton of things in that courtyard since it opens in a v-shape 😃
One more thing I would do, reduce the number of outside doors for maintenance and security reasons. This plan has like 10 of them ha!
Yeah, I see some places that have two doors exiting the same room. You can definitely consolidate a bit.
