Tiny House Trailer Plans:
Through Synthesis we have designed a lot of trailers, and several of them are one-of-a-kind specialty Tiny House Trailer Foundations (not shown on this site). One of the things frequently requested is a low deck (floor) height so that house builders can maximize head space (and loft space) within. So, that is one of the main features of this foundation trailer. To accomplish the task, we include the obvious drop axles, then integrated the floor structure right into the frame. That saves several inches for homeowners and makes a sweet design to build on.
Of course, these are designed as Tiny House foundations, but we have not lost track of the need for interior space within the constraints of the trailer. Even those who like “tiny” appreciate a bit more elbow room and headroom. For a little more space, check out our 24′ Tiny Home Foundation Plans.
Here Are Some More Impressive Design Features:
The engineering in these plans extends well beyond the cut and paste of other tiny house trailers. The frame design is a solid foundation for your new house, including considerations for construction as well as complete analysis to make sure it will perform to the highest of standards. To assure it, we use design tools like Finite Element Analysis to be sure it is not only strong enough, but also stiff enough. A Tiny House trailer frame has some interesting and unique requirements that standard flatbed trailers and car haulers do not. If you are building a Tiny House, this is definitely the way to go.
- The trailer frame is 100″ wide allowing siding and edging to extend beyond the frame 1″ on either side. It allows a cascading over the frame to hide it visually, while staying within the legal limit of 8.5′ (102″) for the house itself.
- Max load capacity (depending on options) is 14,000 lbs. (combined axle rating)* which includes the trailer weight.
- The design includes a perimeter built to support and anchor Tiny House exterior walls. And, the anchoring is flexible to fit your unique floor plan. This makes building on the foundation both easy and very robust.
- Materials selections are for strength and stiffness unique to a Tiny House Trailer. I-Beams to support fore and aft loads; Tube to resist frame twist when loads are not uniform; Frame members to anchor and support exterior walls.
- The trailer deck (house floor) integrates into the frame to minimize floor height and maximize headroom.
- The integration of sides, walls, and flooring with the frame design allows maximum space for the house, both horizontally and vertically.
All this because the trailer design is focus from the first pencil stroke as a Tiny House Foundation.

Reminder: Trailer construction requires metalworking skills and tools for things like cutting, drilling, accurate fixturing and set-up, as well as welding. The strength, durability, and enjoyment depend on how well the trailer is made. Build it well, and Enjoy the Project !!
