‘OH residence’ by japanese practice koseki architect office is a two-storey private dwelling in a quiet residential neighbourhood of osaka, japan. simple and regular in volume, the design inserts a garden space that is bound by a porous, mesh-like facade to dissolve the physical border between the indoor and outdoor environments.

characterized by a pixelated elevation from the street, the house utilizes a large steel mesh with suspended stone tiles that serves as a multi-storey fence by the entrance. the treatment allows for a permeable skin with partial views of the sheltered garden space within. continuing the same language, the roof form that  extends over the outdoor zone features multiple roof lights of various sizes that further provide a sense of open space.

seeking to establish a direct dialogue with the outdoor elements, the interior programs which face onto the garden are lined by floor-to-ceiling glazing. the sliding windows allow the dwelling to easily expand out into the outdoor terrace as well as to promote natural ventilation. visual connections to the garden are continued to the second storey with a small balcony that overlooks the private outdoor space below.
