Hi Diane, this was built for my grandkids also, I have so much labor involved and I used alot of the materials I had around the farm, a person would probably be better off buying one that`s professionally manufactured.
It would be very labor intense to show step by step on how to construct one , I used mostly material I had access to around the farm, and you also have the liability factor if you don`t build it right if someone would get hurt
