The Ultimate  –  Tiny House Foundation

20ft Tiny House Trailer Blueprints

By Your Request  —  The Best Tiny House Trailer Plans!  These are purpose built blueprints for a Tiny House Foundation (the trailer).  If you want a Tiny Home, don’t mess with trailers of a different purpose.  Build your Foundation with engineering specifically for a Tiny House.

Blueprints made for Tiny Homes include a strong perimeter to support the walls, an I-Beam frame for high strength, and floor integration for a low deck, solid floor, and more vertical interior space.  Choose the 20′ Trailer,  the 24′ Trailer,  or the not-so-tiny 30′ / 32′ Trailer.  We even have plans for extra wide foundations  –  10′ Wide,  and  12′ Wide.

Read about designing for a solid foundation, or read the engineering case study.  Then, download the plans for your Tiny House Trailer.
