Yikes, the $7k is like a six month project, they are not like for average American people, everything is in them is like for pigmies, doors are thin and narrow, everything is thin. For $7k, not going to get much or any insulation. Most of these tiny homes go for $25k and up. I know if I attempt to build this, it be harder than building standard small building, plus I believe most of them are on frames you drive down the road. Plus, hope your knees are solid as sleeping seems to always be lofts that you crawl into. I would need an elevator, LOL. If I was to consider smaller living, I would refurbish smaller freight cargo trailers, like coming out of China, most have good solid flooring, and thicker walls. I think you can buy these out of Houston for $2,500, get blueprints of small home to get idea of cabinets, etc. Some builders where I live are making regular homes out of these and even Starbucks in Wash St are using them to make coffee.
I have had crazy ideas like buying 50 of them and renting out as hunting mini lodges out in boonies.
