In Japan, modern prefabs have been around so long that they are into their second life as renovations. Dwell shows an interior retrofit by Koji Asako of Geneto, a Japanese architecture firm, of a 25 year old unit. Audrey Tempelsman writes "Japanese prefab became popular at the end of the 1970s, when the economic boom began to slow. Relatively cheap and easy to construct, prefabs filled the suburbs of Tokyo and Osaka, giving the suburban landscape its aesthetic identity. For Koji, the preservation of this prefab’s exterior in the Shiga province near Kyoto was a nod to its historical and social significance."
I love the stair, of course completely illegal in North America. ::Dwell
