Description
The not so tiny, tiny home foundation. Build the long foundation for your new home with these Tiny House Trailer Plans. Build it at 32′ or the optional 30′ length — just one of many options in the plans. Either way, these blueprints are the start to a solid foundation for your new tiny house.
With 32 feet, tiny is not so tiny, yet these Trailer Plans have a focus specifically for building a Tiny House on Wheels. With strength and stiffness right to the edges for supporting the walls and roof loads, so you can build the trailer to last a lifetime.
All plans are FULLY ENGINEERED, and designed from the start as a Tiny House mobile foundation. They are not a revised from a utility flatbed or car hauler.
Plans include many features to make your tiny home better. Strength at the perimeter for the walls (including all the needed wall anchoring accommodations), construction techniques for easier building and a flat floor. Speaking of floors, who doesn’t appreciate vertical headroom (and loft space)? For a low deck (floor) height, these plans integrate floor support into the frame. For homeowners, these plans make a sweet trailer design to build on.

The trailers at on Mechanical Elements are designed and fully engineered for the jobs intended. Since Tiny House trailer plans have unique needs, we designed these for the exact job. You requested a 30+ foot design, so here it is with a design for minimal deflection in a trailer this long. We like challenges, and in this case you benefit from the work.

More About The Design Features
More About The Design Features
As we design one-of-a-kind specialty Tiny Home Trailer Plans (for individuals with specific needs), we learn about the importance of certain features. Now, we’ve pulled them together in these plans (and our 24′ version and the shorter 20′ plans) so you get the engineering benefits without the custom trailer plans price!
One frequent desire is a low deck (house floor) to enhance the interior headroom (within legal height limits). That is one great feature of these tiny house trailer plans, and it comes from innovative thinking and careful engineering. Of course it has the option for drop axles, but we did a lot more. The floor integrates into the frame which saves vertical inches, because living tiny does not mean cramped.
Specifically As Tiny House Trailer Plans

Engineering in these plans includes all we learn from other tiny house trailers. Since every house deserves a solid foundation, this frame has a cool construction technique to simplify building and help make everything straight and flat. But it’s even more. We use the great engineering tools like FEA (Finite Element Analysis) to back up our claims of “Stiff” and “Strong”. If you are ready for a new Tiny Home, then this is the way to go.
- Trailer frame is 100″ wide so finish siding can extend beyond the frame 1″ on either side. This hides the frame, while staying within the 8.5′ (102″) legal limit.
- Capacity is 15,600 lbs. (including the trailer), or the heavier option for 18,000 lbs. total capacity.
- Design includes a perimeter ledge to support the walls. Anchoring is flexible to fit your unique floor plan and make building both easy and robust.
- Material selections are for strength and stiffness unique to a Tiny Home Foundation. I-Beams for the main loads; Rectangular Tube for crossmembers to resist frame twist; The floor and exterior walls bolt directly to the frame.
- The house floor integrates down into the trailer frame to lower the floor and give maximum head space.
- Integration of sides, walls, and flooring with the frame design allows maximum space for the house.
All this because the design has focus — from the first thought — as Tiny House Trailer Plans.

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.
