taku sakaushi / OFDA: three windows

‘three windows’ by tokyo-based practice taku sakaushi / OFDA is a private residence on a sloped mountain side in japan. true to its name, the design features three large windows that frame a specific view of the site, drawing the elements of the landscape into the interior as backdrops for the living space.

facing the far-away mountains to the south-east, the town to the south-west, and the surrounding forest to the north, the form of the layout was informed by the views offered by the vantage point. spreading out from the centre, the main communal space is arranged in an open fashion on the ground floor. an artificial landscape of the inhabitants’ functions are created by a series of platformed levels which, in addition, define and separate the space.


outfitted with expansive stretches of glass, the design seeks to blur the boundary between the interior and exterior. the windows provide abundant natural daylight as well as facilitate cross ventilation throughout the house.
