What 3 decorative areas/buildings in-game do you wish were functional?

The previous games spoiled me so much. I think every bit should be usable.

The main ones I hated and was really disappointed at were Mt Komorebi and the eco world. They have high quality shells all around and they're completely unusable and just a waste of space. I need homes for my families and yet here I am again with 5.

Anyhow...I finally started using TOOL to add things off lot and I can honestly say that I love the few changes that I have made so far. That one river bend neighborhood in Willow Creek I added a swing set, chess tables, and the kids play tent that came with a pack recently. Now I see the sims walking around the neighborhood using the chess tables and the neighborhood kids use the tent autonomously.
