Dezeen's India Block reports that British architecture firm Invisible Studio has designed a prototype of a mini prefab trailer that cost just $28,000 to build.

Located in Bath, England, the micro structure measures 40 square meters, or about 430 square feet, and can be used as a dwelling or workshop.The home's repurposing of salvaged materials, including corrugated fiberglass and steel, plywood, locally grown unseasoned timber, and polycarbonate “glazing” on the gable walls kept costs minimal.

"The project aims to provide a super low cost, versatile, useable space that could act as a kit of parts for any self builder to improvise around or easily adapt," said Piers Tayler, architect and founder of Invisible Studio to Dezeen."While conceived as a domestic space, it could easily function as a workspace or something else."

Inside, the rectangular plan has a living space that runs the entire length of the structure, with a gas stove in the middle. A toilet and a small cooking area are set either side in the in the wides part of the hexagonal structure.

Two ladders give access to two sleeping platforms at either end of the home, one of which is accessed via a wooden walkway suspended over the main space. All the insulation was scavenged, the doors were found in a skip, and the skylights set into the roof were obtained cheaply as factory seconds.

Rope handrails strung the mezzanine levels and walkways are made from offcuts of the blue rope used for one of the architects' earlier projects, Studio in the Woods.
