There is an old hot tub structure in our backyard that takes up most of our backyard space. The structure is about 8' x 8' with a roof, electricity, and gas. The hot tub was removed years ago so the floor is a cement pad.

Any ideas what to make out of it? LO will be 2 in Feb and we'll have another one in June. I was thinking it could be an awesome playhouse. I was thinking of kid proofing the space and adding a toy kitchen and table like a little house. I'm open to other suggestions. I'd like whatever we do to last a long time.
