Description

Enjoy this sturdy Tiny House Foundation for your own custom home.  Begin with a solid foundation.  It then allows confident Tiny House construction, knowing the foundation is secure.  After all, the tiny house trailer frame is the foundation.

These plans are for a 20 foot length, 8.5′ wide trailer, with a design specific for Tiny Houses.  Engineering is for strength, stiffness, and a lifetime of service.  These are the Trailer Plans Only.  Build the trailer as the foundation, then build the dream house with floor plans of your choice.

The trailer includes a low deck (floor) height, which comes from drop axles and underslung springs – then special features with the floor integrated into the frame.  It saves several vertical inches to maximize head space (and loft space) within.

The trailer frame design handles wall weight at the perimeter, for holding the roof, snow-load, loft, etc.  It is also designed for all the necessary wall anchoring — with graphics showing you the recommended attachment.  These are just some of the practical features of our foundation trailers.  For homeowners, it makes a sweet design to build on.

Of course, these plans are FULLY ENGINEERED, specifically as Tiny House foundations.  They are not a re-boot of a utility trailer or flatbed.  Also, plans include unique construction features to assure the foundation is straight and much easier to build.

More About The Design Features

Finite Element Analysis on the Tiny House FoundationThe 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.
