Lightwell House by Keiichi Hayashi Architect
Via @designboom, a two-story house in a dense residential neighborhood of Kyoto, Japan. "Singularly treated in a reflective white finish, the interior surfaces maximize on the natural daylighting effect. Hollow, pylon-like structures interspersedly pierce through the second floor, acting as light chimneys for the level below." More at Keiichi Hayashi Architect. Photo: Yoshiyuki Hirai.
