Are you a DIY builder looking to build your own tiny home on wheels? Not sure how to start your subfloor and attach your home? For those who would like a solid start to their tiny home without the start-up headache for their trailer and foundation prep, we offer trailer foundations!

Typical trailers are just that. Trailers. You still have to protect your home from insects, vermin, and moisture. You need to attach your home to the trailer. You need to choose the right insulation for fire protection. What about thermal bridging? How do you inset your floor to maximize your loft height? Let us worry about that.

Our foundations come with the trailer, floor framing, full insulation with vapor barrier, full trailer flashing belly pan, and flooring subfloor. We offer utility trailer foundations from 12-ft through 30-ft. We offer dual axle 10K trailers and triple axle 15K and 21K trailers and we offer different levels of insulation. Let us take the guesswork out of your first step towards your DIY tiny home.
