Right now, I have:
A light forest-like themed entrance (but not really) that leads to the museum.
Museum that kind of looks like a park (near the entrance).
The museum also has a waiting area and a little amusement area/food stall in front
A terraformed wall on my Resident Service and a fountain surrounded by tiny waterfalls.
Outdoor bath/little zen area beside my house
Beach side bar/cafe in front of Nook's and Audie's house.
Also, a parking lot/car showcase on the same beach.
Mini-playground areas near the big cafe.
The big outdoor cafe near my heart pond at the back of Merengue's house that connects to the amusement center with music/band area.
A resting area with swimming pool and a little picnic area with cushions.
Tropical-themed resting area on top of the highest waterfall at the center of my map.
Small resting area with rocks.
Diner area near my secret beach.
Garden that overlooks the lighted parking area.
Farm with a pair of silo(s) built.
Maze-like formation on the way to the turbines.
Then the place where I built the turbines, solar panel and antenna then an incline that goes down to a path to diana's house.
Little laundry area, sewing a coffee near her place.
Bamboo resting place by the beach and a bamboo picnic area beside Lily's house
Campsite area
Outdoor presidential suite like area near my big center waterfall.
Soccer/Sport area and Drawing/Painting school by the beach.
Lighthouse on my peninsula.
Then another picnic by the beach area in front of my house (I love picnic lol).
