The minimalist Japanese retailer Muji have built a vertical house in Tokyo designed to accommodate and enhance modern city living. The Muji house has been built with the aim of maximising the potential of its small plot in a city where space is of a premium. With an absence of internal walls or doors the home is airy, light and spacious. We particularly like the spilt-level system which bring the concept of open living throughout the three floors of the dwelling. The minimal and functional design of the home mirrors the brands approach to the rest of its retail output and puts forward a lifestyle that few city dwellers would find hard to resist. Come on Boris – give Muji a contract for new London homes! All images courtesy of Muji.
