Japanese design brand Muji has revealed the prototype for its latest prefab house, which it will test by having a competition winner move in rent-free for two years (+ movie).
Located in the seaside city of Kamakura in Japan's Kanagawa Prefecture, the ready-constructed dwelling is named the Window House after the assortment of frameless openings that characterise its facade. It is adapted from a 2008 design developed for the brand by architect Kengo Kuma.

In order to test the prototype, the Minimalist retailer is inviting one person ? along with their family or chosen flatmates ? to live in the home for two years.
In exchange, the residents will be required to provide regular feedback to Muji's researchers and designers about their living experience. The winner will be picked based on an application process.
With two storeys and a total floor area of at least 80 square metres, the house is the largest prefab dwelling so far from Muji.
The company's previous models have included the Vertical House, created to fit into the narrow spaces of Japan's cities, and three different holiday huts by designers Konstantin Grcic, Jasper Morrison and Naoto Fukasawa. Kuma also developed another design, the Tree House, for the company in 2009.
