Description
Description
If you want a wider, more livable tiny house, consider these 12′ wide x 32′ tiny home foundation trailer plans. This is our extra wide, triple axle trailer design specifically for the needs of a Tiny Home. Build it at 32′ or 30′ length — just one of the options.
At 12′ wide and 32′ length, this tiny home trailer is not so tiny. 384 sq ft. platform. Great for a small home with more livable space. The extra width makes great things possible within the house. It’s also very close to the International Residential Codes Appendix Q definition for Tiny Houses limit of 400 sq ft. (See notes below.) One option shows how to achieve the full 400 sq ft.
All our Tiny House Trailer Plans include Engineering specifically for strength and stability as a foundation for building your home. Build it to last a lifetime. We also offer a traditional 8.5′ Width x 32′ Length, and a not quite as wide version at 10′ x 32′ foundation platform.
12′ Wide x 32′ Tiny Home Trailer Plans
The trailers at on Mechanical Elements are designed and engineered for the jobs they’ll do. And, that is certainly true with our Tiny Home trailers. We address the unique needs of a trailer with a house on top. We also address the needs in ease of construction — making it better — whether you build it DIY, or have someone build it for you.
In our article on the size quandary, you requested an extra wide version of our popular 32′ design, and here it is. These are 12′ wide x 32′ tiny house trailer plans. Like the standard width, this trailer frame is optimal for minimum deflection. Read the Engineering Case Study for Tiny House trailer design on the Synthesis website.
We have designed several one-of-a-kind Special Purpose Trailers, including Tiny Home Trailers (for individuals with specific needs). And, we’ve learned a lot about the importance of some of the 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 full price!

12′ Wide x 32′ Tiny Home Trailer Plans
- High capacity triple axles for maximum support.
- 12′ x 32′ nominal bed size, or use the 30′ length option. (Frame size is 142″ width for a final house finish at 12′ width.)
- 18,000 lb. capacity. * For more strength than you should need.
- Full Engineering on plans design for Strength and Stability and a lifetime of exceptional performance.
- Full strength design to support wall loads at the perimeter — because the outside walls typically carry the primary house weight.
- 12′ wide tiny home gives room for livability and makes more possible inside.
- Special frame design makes a low floor, optimizing internal head space, while also making easier trailer construction.
- Options to build it just right are in the plans.
- Plans include detail drawings and instructions with illustrations. It’s all in the download.
One frequent desire is a low deck (house floor) to enhance the interior headroom. That is one great feature of these tiny home trailer plans, and it comes from creative engineering. Of course it has the option for drop axles, but we did more. The floor supports integrate into the frame which saves vertical inches to maximize interior space. Now with this design, we’ve made the trailer design even wider, because tiny does not have to mean tight.
More About The Design Features
More About The Design Features
Engineering in these plans includes all we learn from other tiny home trailers. The frame is a solid foundation for your new house, including 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, this is the way to go.
- The trailer frame is 142″ wide so siding and edging can extend beyond the frame 1″ on either side. This hides the frame, while staying within a 12′ width.
- Total capacity is 18,000 lbs. (including the trailer) total capacity.
- Design includes a perimeter ledge to support the walls. Anchoring is flexible to fit your floor plan and make building both easy and robust.
- Material selections emphasize strength and stiffness for your Tiny Home Foundation. I-Beams for the main loads; Rectangular Tube for crossmember strength and 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 maximize head space.
- The integration of sides, walls, and flooring with the frame design allows maximum space for the house.
All this because this trailer design is for a Tiny House Trailer Foundation, right from the start. These are the widest we have — to build a 12′ wide tiny home. For more information on our Wide and Extra Wide Tiny Home Trailer Plans, please see this introductory article.
Start Your Tiny Home Right
No doubt, if you are looking for a sturdy, yet wide Tiny House Trailer as a Foundation, these plans are worth considering. The extra space of the 12′ x 32′ tiny home trailer in these plans gives breathing space. If your Tiny Home will not be on the road much, these plans deserve a long look. Build it to last a lifetime – and more. Build it well, then it will serve you well.
Order the plans above, then save them to your computer immediately — right here at Mechanical Elements. You can start construction right away! The solid foundation from these 12′ wide Tiny House Trailer Plans is the first step to a fantastic new home.
Please Note:
- In most jurisdictions, because of the extra width, this trailer will require special permits to travel on public roads. Please make sure our extra wide 12 x 32 tiny home trailer plans will work for your situation.
- ICC AQ defines Tiny Houses as 400 sq ft. or less (not including lofts). Bigger than that, puts the house in a different code category with different rules.
- If you wish to hit that 400 sq ft. limit, this trailer can expend 6″ width making it 12.5′ x 32′ which is a 400′ sq ft platform. Other calculations come into play with your floor plan in calculating square footage. We leave that to you.
- While 12.5′ width is an option with these plans, in some areas, going over 12′ wide is a different category for towing. Check your requirements.
- Check your local laws to see if they’ve adopted the ICC standards for Tiny Houses. This trailer meets the requirements, but it’s good to know everything that applies.

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.
