Description
Description
A sturdy Tiny House Foundation for your own custom Tiny Home. This is the solid, secure foundation which allows confident Tiny House construction. After all, the tiny house trailer frame is the home foundation.
These plans are for a 20 foot length, 8.5 foot wide trailer design specific for Tiny Houses. Engineering is complete for strength, stiffness, and a lifetime of service. Trailer Plans Only. Build the trailer as the foundation, then build the dream house atop with the floor plan of your choice.
The trailer has a low deck (floor) height, using drop axles and underslung springs – then special features with the floor integrate into the frame. The design saves several vertical inches so you can maximize interior headspace (and loft space) within.
The trailer frame design handles wall weight at the perimeter, for holding the roof, snow-load, loft, and more. Drawings show the recommended wall anchoring along the sides of the trailer, securely anchored. These are just some of the practical, standard features of our foundation trailers. For homeowners, it makes a sweet design to build on.
Of course, these plans are FULLY ENGINEERED, specifically as a Tiny House foundation. They are not a re-boot of a utility trailer or flatbed. And, plans include some unique construction features so the foundation is straight, and much easier to build.

More About The Design Features
More About The Design Features
The engineering in these plans goes beyond cut and paste from other tiny house trailers. Since you want a solid foundation, the frame design passes a complete analysis to make sure it will perform at the highest of standards. To assure it, we use tools like FEA to know it is strong enough, and also stiff enough. A Tiny House trailer frame has unique requirements that standard flatbed trailers and car haulers do not. So, if you are building a Tiny House, this is 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.
- A 12,000 lb capacity option is included. Either way, it’s good to have more capacity than you need.
- The design includes a frame 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 selection are for strength and stiffness unique to a Tiny House Trailer. I-Beams 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 has focus from the first pencil stroke as a Tiny House Foundation.

Notes for Success
* Trailer load capacity depends on all the parts and materials, as well as the craftsmanship in building. All Mechanical Elements trailers are engineered to perform as stated when built as defined with proper care in construction – including parts, material, construction techniques, weld integrity, assembly methods, and finishing. Capacity for this trailer also requires proper choices for parts such as the hitch, axle(s), wheels, tires, safety chain, decking, bolts, pins, etc. Please make sure component load capacities match or exceed the trailer total capacity. Do not exceed manufacturers limits.
For trouble-free trailer life, think care and safety. Please select fastening methods to handle how and where the trailer will operate – including vibration, proper fastener types, bolt grades, torques, and nut types (like lock nuts). Then, be smart about loading the trailer, load distribution, tire pressure, tire condition and the mechanics of towing. We want you safe to enjoy your trailer for a long time ahead. Always use proper safety and securing equipment when loading and towing a trailer.
