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.

Extra Wide Tiny Home Trailer Plans

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!

Specifications

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.

FEA on Tiny Home Trailer
20′ Trailer Analysis in this Image. The 32′ Frame Analysis is Similar.

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.
