Durable and versatile

To create a strong and reliable prefabricated house kit that endures whatever Mother Nature throws at it, we incorporated termite-proof composite walls and roof panels that are impervious to termites, mold and corrosion. Manufactured with coil-coated galvanized steel sandwiches fire-retardant polyurethane insulation to help keep people and contents up to 15% warmer in winter or cooler in summer than outside temperatures. Snow load tested to 50 lbs per square foot and boasting a key lockable door with deadbolt, this resilient garden house and tiny home kit is ideal for storing tools and equipment as well as soft furnishings like couches and bedding. It also makes a comfortable cabin kit for building off the grid.
