I'm trying to find the name or any information about a project that was featured on Bob's TV show many years ago. (not sure if it was This Old House). The house required no foundation -- you could use concrete piers to support it. It was built using a series of panels (8x8 I think) that you could make into rooms of various sizes. They were advertising it as sort-of a do-it-yourself construction project. I remember it had some sort of integrated electrical bus, where each room you added plugged into the bus.

Does it still exist?

thanks,

Eric
