Instant House is a home easily built and liberates living. It can be built in a few hours, first by using a blower to in.ate the membrane like a balloon and then by applying thermal insulation material including high air content from the inside. The shape, size, and functions can be chosen freely, and the lightness allows even amateurs to create them. It is also inexpensive, simple, fast, technical, and versatile. The simple structure consists only of the membrane and insulation, and the design of the structure, both large and small, provides excellent thermal and sound insulation properties. Therefore it is extremely resistant to the effects of external factors such as cold, heat, wind, rain, snow, earthquakes, and strong winds. It realizes a lifestyle with minimum energy consumption.
(Description / KITAGAWA Keisuke) Launch Year / 2020


Easy assembly-type living space is generally created and supported by internal columns, external ropes, or combined walls, but this instant house is different. With the dome-shaped fabric and insulation, the house shows a unique rounded presence both on the exterior and interior. Its construction method is flexible in size, with options to change the heat insulation and fabric. We can surely expect the expansion of the variety of designs and applications.
