If the site has been properly leveled, the external walls of the structure can be erected in as little as 30 minutes. The floor, roof, and walls are all hinged and swing into place with minimal assistance. The internal separations are determined by the design, but snap together and form the dividing walls inside the structure. The setup of the basic structure, and the hook up of water, and power can take approximately 2 hours. The installation of internal living space including doors, closets, walls, sinks, toilet, shower, cabinets, etc. as well as other cosmetic enhancements will add additional time.
