Architecture, Building and Structure Design Timeless Residence by Satoshi Kurosaki Inside, the house is defined by two courtyards, one large and the other small, that are arranged in parallel. The main courtyard is on the south side and features a bamboo grove that draws the eye when one steps into the entryway. A smaller slit-shaped courtyard on the north side is also dotted with plantings and serves as a lightwell, filling the first-floor living room and entryway as well as a second living room upstairs with pleasant, diffuse light.
