I used Ana's plan as a base.
I changed it from 8x8 to 8x12, made the 4x4x8's to 4x4x10' for a higher main platform and swing platform, and added a 12' long monkey bar set to the other side. Also, an 8' climbing wall and a plank walkway to accompany the two slides.
For the clubhouse, I used Hardiplank 4x8 sheets for the siding and an EZ-Framer kit for the structure itself.
The slides I purchased from Lowes, monkey bars from Amazon, and the swing frame braces from Amazon as well. The swing kits I got from ebay.
