setsuko sakakibara architect & associates has completed an irregular-shaped duplex house in a suburban residential area in hyogo, japan. the pre-existing structure was formed about 50 years ago and was featuring 400 sqm per block, but now, each volume is limited to half of the area. the architects sought to generate a black wood-clad structure with unevenness by constantly dividing the building into multi-level blocks and shifting the angle to the site.

in an attempt to foster a diverse and playful place and take advantage of the height differences of the site, setsuko sakakibara architect & associates has formed various levels in the house. this way the line of sight could be pathed and the height could be changed. furthermore, a small garden, created by the disparate arrangement, provides the inhabitants with multiple places such as a children’s playground, bath court, and clothesline.

a skip floor took form on the parents’ zone in order to promote their interaction and communication that is attributed to the openings as well. natural light penetrates the large windows on the child area and high side openings in the kitchen look towards the roof terrace. moreover, the ceiling height of the kitchen is about 3,5 m, of the block that features the living area is 2,1m creating a cozy ambiance, while the one of the tatami room that surrounds the dining table is barely 2m. meanwhile, the rooftop provides its occupants a panoramic view of the town.
