Japanese homes are often designed to last a relatively short time before being demolished and rebuilt, so it's little wonder that the country produces a disproportionately high number of quirky residences. The Transustainable House reflects this trend, and sports a facade that rusts over time. In addition, despite measuring just 38 sq m (409 sq ft), it can house up to three groups of people at once.

Designed by Japanese architecture firm Sugawaradaisuke, Transustainable House is located in Chofu, Tokyo, and was completed earlier this year. Though small, the interior of the house features plenty of natural sunlight and a flexible layout that can be adapted to suit the needs of the occupants.

Indeed, Sugawaradaisuke's plans show up to three groups of people – a young couple, their parents, and a boarder – all living under the same roof following a re-shuffle of furniture. This setup seems sure to test the residents' patience to breaking point in what remains a single bathroom home.

When configured with its standard layout, the Transustainable House features a kitchen, dining area, and one bedroom upstairs. The downstairs comprises a couple of flexible semi-outdoor spaces covered by the same stone pebbles found around the home's plot and garden areas. There's also an additional bedroom, and a bathroom that appears to be alarmingly lacking in privacy.

In order to achieve the Transustainable House's rusted facade, Sugawaradaisuke mixed plaster with iron powder. It should continue to weather over time as it is exposed to wind and rain.
