designed by keitaro muto architects, ‘sunomata’ is a single family residence composed of stepped rectangular volumes, which rise sequentially to create a two-story structure. located on a corner lot adjacent to rice fields in the city of ōgaki, japan, the project replaces an existing house, doubling the size to accommodate the clients’ extended family. the building is largely closed off facing the street, while opening toward its private garden on the interior of the site. this outdoor space is situated around large and sculptural existing stones, situated in a gravel landscape.

the design’s stepping movement of the overall building volumes is intended to rise from the rice fields to the west of the site. this arrangement serves to organize the interior spaces, which are all oriented toward the south side of the property, and open either visually or physically to the japanese garden.
a large void in the building along the street allows for a carport and covered entry walkway, the latter of which passes by the rock garden to approach the front door. on the ground floor, aligned door frames break through the primary walls to create a central circulation axis. the program includes two living, dining, and kitchen areas, with one designated for use by the parents. an open tread staircase accesses the upper level, which contains the residence’s bedrooms and a small balcony.
