I built a giant green house there, one side has a cafe, the other side has a roller rink. The lot functions as a cafe. On the first floor is a walkway that goes all around it so you can see the plants from above. I might change the roller rink for some planters and create a real gardening space for the sims in the future, but I quite like it as it is for now, it has a really nice feel to it especially when it rains heavily outside.
