The glass walls give the houses a natural light, and exposed wood beams and framing gives these minimalist interiors a strong and structured look. Japanese architecture firm Naf Architect & Design created this Zen style home; a contemporary two-volume house with separate structures that are still unified. One volume is used in daily, single-family living, while the other provides privacy as a work space, for entertaining and accommodating guests, or perhaps as a second suite. The use of the same materials in each volume – plenty of glass and wood – creates a sense of continuity. The fronts of the two houses are carved with a continuous divot, an unconventional element that further solidifies the sense of two-in-one. But despite their physical similarities, these mirror-image houses play very different roles. for more information please visit Naf Architect & Design site.
