What Type Of Trailer Foundation Are You Looking For?


Tiny House Basics is #1 source for tiny house trailers in the United States. We proudly build foundations specifically designed to support your dream tiny home. We build all sizes in full foot increments up to 54ft in total length. Each trailer is custom built and can be designed to your specific needs and built to handle the unique loads of a tiny house around the perimeter of the trailer frame. We DO NOT use flanges (flat stock steel) on the sides like our competitors (which causes mold issues under the framing) All our trailers are built from box tube frames and crossmembers and can be uniformly insulated in the floor. Choose your ideal tiny house trailer through our custom quote form and Let us share with you our experiences as builders and dwellers for almost a decade to get you started off on the right foot!
