japanese practice naf architecture and design was commissioned to complete an interior renovation of a 4-story, 17 year old home in a dense neighborhood of tokyo. the layout of the existing rooms made little sense, especially considering that the new house was to serve a family of three with a chiropractic clinic. in order to consolidate the bedrooms, entertainment rooms and businesses in one pre-existing form, a timber box, dubbed a ‘switch box’, was installed in the very center of the building acting as a spatial intersection for all functions. accepting visitors at the front door, the switch box acts as a waiting room to the chiropractor’s office, the vertical circulation to the living room, bedrooms, and karaoke room in the basement.

the remainder of the structure by contrast is rendered in a stark white color, including walls, ceilings and structural elements. the box, made of deck wood, serves an important role in circulation but also interacts with every other space. the roof is peeled back, allowing natural light from the skylights to reach the ground levels. the top of the box reaches high enough to serve as a desktop for the living room area, and smaller areas off to the sides of the box allow for noise transmittance while blocking visual connections- allowing for privacy.
