I believe the owner is Malcom Morrison, who lives in Pennsylvania.  He and a couple of friends restored the fuselage of an Aero Commander 500 and made it into a kids playhouse that can be moved around on a small trailer.

He has a history of the project and an explanation of some of the ways that he made the ‘aircraft’ more kid-friendly.

They did a beautiful job!
