this two-storey residence in sapporo is defined by its pared down and similar interior and exterior material palette. clad in a polycarbonate paneling ‘house in shinkawa’ by yoshichi katakagi + associates follows the form and thermal system reminiscent of a greenhouse. its transparency and material protects the home from the elements, while diffusing light into the interior. without insulated walls, the house is heated through its positioning on the ground; supported on the earth and a sun room at its core. this terrace-cum-sun room emphasizes the relationship between inside and outside, while giving the 53 square meter area an illusion of a larger space. furthermore, the orientation enables it to receive the most sunlight: from spring to autumn it serves as a living space, and in the winter, the glasshouse effect keeps the home warm.

the dwelling has been kept bare and minimal with little adorment




compact and with little surface finishes, the minimal home is supported by an exposed timber frame. its low maintenance and economical construction has resulted in a functional and well-insulated home ideal for the inhabitants who resides.

the layout and section of the home

  • It is important to note that the primary living spaces can be opened or closed from the “greenhouse” as required by the seasonal temperatures/weather. A beautiful example of traditional Japanese architecture blended with 1970’s American passive solar technique.

  • Interesting design

  • outstanding!
