He is averse to air conditioning, but she can't stand the heat. The couple hired local Ehime studio Takashi Okuno & Associates to design this modern Japanese home, where they can dwell comfortably while enjoying climatic conditions that are ideal for their health and wellbeing.
To meet their requirements, the studio’s lead architect Takashi Okuno used diatomaceous earth—a soft, sedimentary rock that crumbles into a white powder and provides good thermal insulation—for the walls and floors of the 1,570-square-foot residence.
To maintain airtightness and retain heat in the colder months, Okuno fitted the home with external aluminum blinds, high-performance sliding wooden window frames, and insulating screens.
This allows the couple to close off the interiors during the summer months to keep the heat out, and open it up during winter to take in the warming sunlight without losing heat.
After surveying the wind directions on the site, Okuno created a wind chimney above the kitchen to promote ventilation.
Cedar rafters were used in the living room to give the space a sense of expansiveness.
A built-in sofa was positioned near a window, where soft sunlight streams through.
A latticed, sliding partition can be opened to connect the living with the dining area, or closed to separate them.
One of the bedrooms faces a sun-drenched inner courtyard with a raised deck that’s accessible via the living room.
In the dining room, a row of potted orchids sit within planters along the interior windows, so the couple can admire their orchards and look beyond the plants into their Zen-like courtyard.
