You can purchase plenty of little items to fill your home at Muji, and now the Japanese retailer has unveiled the designs of three tiny houses.

Designed by Konstantin Grcic, Jasper Morrison, and Naoto Fukasawa, the prefabricated huts are designed as weekend getaways and can be easily installed in rural areas. 

Konstantin Grcic created a vertical tiny house measuring 3 x 3.3 x 4.5 metres, which requires no building permit in Japan. The hut uses a composite wall system of an outer aluminium layer and a inner plywood layer with insulating foam in the middle. Internally, the hut features a flexible open-plan space with a loft area for sleeping.

Muji Hut by Jasper Morrison is designed to be "a small house with everything needed for a short stay." It features a wood-burning stove, a kitchenette, and a bathroom.

Muji Hut by Naoto Fukasawa is designed to evoke the "feeling that one could slip into nature anytime." Fukasawa’s pitched roof hut includes a large, Japanese-style bath, a small kitchenette and a trestle bed, all surrounding by an expansive glass window-wall.

The prefab huts will be on sale in Japan next year. They follow Muji’s prefabricated house project which went on sale in Japan in September 2015, where customers could purchase a 4.4 metre wide, three-storey kit house for around AU$298,486.
