We didn't have plans but my dad and dh just built it from looking at all the swing set pics online. We ended up getting a 2 person swing fairly cheap on ebay and the slide and belt we got at Lowes. We already had the baby swing. We got real climbing rocks on ebay cheap too.
Do you mind if I ask how much it cost you altogether? (Feel free to PM me if you don't want to post it.) I think we'll probably do one without a fort/playdeck because we're going to put it right next to our small second story deck, and DH said he would build a playhouse under the deck so I don't think we need a fort besides.
