This basegame national park is the way to go when filling a 50x50 lot. There's everything you need: a gym, a bar/lounge, a pool, hot tubs(for many woohoos), grill space, kids playground, lots of skillbuilding items and your sims can even get married here, all without touching simsie's walls :) It fits every lot requirement so you can change it according to your desire, as aquatic park & gym may not be the best name #SadSimsieShell #basegame #lilsimsie
