japanese architecture office alphaville, led by kentaro takeguchi and asako yamamoto, has completed a three storey dwelling in the densely populated city of osaka. the residence, uniquely named ‘dig in the sky’, is composed of three individual buildings that sandwich two external courtyards – bringing daylight into the narrow plot. as each of the three volumes only contains one room on each floor, a tube-shaped corridor was devised in order to connect the entirety of the scheme. consequently, each room is separated by circulation space, rather than orthodox doorways.

within the design, a guest room is found at ground floor level, with primary living accommodation located above, alongside a bedroom for two children and a small study space. at the uppermost level of the plan, the master bedroom is joined by a bathroom, while an external balcony provides further natural light and ventilation.
