The wooden houses are prefabricated, loaded onto trucks for transport and unfolded on site in hours (adding the windows, drywall and interior finishings takes about two weeks).
The first design was the Model A (an A-frame), but the company soon released the Model-T (for "trapezoid") to gain more space on the second floor. There is no need for a concrete foundation since the homes can be placed on screw piles. The homes begin around 51 (550 square feet) and can grow depending on how many modules one purchases. The only limitation is the modules need to be placed in line, so the company suggests stopping at the "villa" size of 127 square meters (1367 square feet). The units are prefabbed with a selection of cladding, roofing and flooring.
The homes can also be folded back up and moved, as easily as they unfold, making it possible to reuse them at a new location. The hinge system construction also provides flexibility in the home during an earthquake, allowing it to "disperse the energy of earth tremors" and weather seismic phenomena.
