For me, it would be:
Girl (18pts) -- It's obvious why
Workout room (5pts) -- It's important to stay fit, and it can be a nice change from the other physical exercise
Garden & greenhouse (2pts) -- You can go outside then. It's nice to be able to be surrounded by plants now and then. Plus, it allows to dive into the bushes with the girl
Skylight (2pts) -- Some natural sunlight is mighty important, especially if you're in a basement. Plus, with that, I'm essentially in a house instead of some basement (natural light + garden == close enough to a house)
Hygiene products + jacuzzi (3pts) -- I had points to spare and the jacuzzi can be fun with the girl.
