I think we have decided to build our tiny houses on trailers. What we sacrifice in square footage we gain in mobility and freedom from the building department. We would no longer be forever tied to one location and I just think our odds of flying under the radar are better. Instead of 10x20 with a generous loft we will be doing 8x20 with a micro loft. It will necessitate constructing one additional tinyhouse but that's okay. We can always sell the extras when the kiddos fly the coop or my wife's idea, start a bed and breakfast. I'll post some pictures of the new concepts soon.
