Let’s Get it Started! -Subfloor Framing

The next decision we had to make was what size exactly our tiny house was going to be. Legally, we had to keep it under 8′ 5″ wide and 13′ 5″ tall to take our tiny casa on the road without a permit. We mocked up our floor plan in the sun-room of our apartment. We decided we could fit all our things in an 8 ft by 14 ft space, provided we had the ubiquitous sleeping loft and storage loft. Now we needed a trailer. This is the first big purchase you will make if you decide to build a tiny house, and it’s a darn important one! After scouring craigslist again, we found P&T Trailer Sales, Inc, based out of Hunstville, AL. They gave us a great deal and built it to order.

Will’s father graciously allowed us to use his yard as our building site and gave us full access to his impressive collection of tools collected over years of home building projects. Many thanks! 🙂 We built the subfloor out over the wheel wells of the trailer to give us a full 8 foot foundation (2×4 construction).

We doubled up the floorboards of the trailer to get it level with the lip of metal frame.

We covered the bottom in aluminum flashing, and filled it with rigid insulation. We bolted it down with lag screws and covered it in thick subfloor plywood. Voila! The foundation is complete!!!
