Wasn't sure where to put this one. It is designed to be a tiny house. It could fit the "tiny house on a HF frame" topic. It is a bit large to be a TTT, but I must add that it's just crying out to be a Foamie. I think folks on this forum could come up with quite a few improvements on the layout, fit, & finish of this design, but I suspect the original builder could as well.
