Earth-Temperature Architecture "Moon Stage" in Hachioji
This unique detached house in Kinugao, Hachioji, is a residence designed to live with the earth's temperature and the forest's breath. The property is built by digging into the ground along a cliff, creating a structure where floors and walls directly touch the earth, offering an enveloping sense of security. It features a dramatic ceiling height exceeding 5 meters in the living area, combined with openings that create temperature differentials for a comfortable space. The earthen floor space without a subfloor incorporates the earth's warmth, while vacuum insulation and radiant heating/cooling create a comfortable living environment without noise or drafts.
The kitchen is finished entirely in wood, minimizing the number of craftsmen involved and achieving a unified material aesthetic with careful handiwork. The warmth of wood accompanies daily life, creating a special kitchen with a calm, beautiful atmosphere. Gentle breezes pass through, keeping the air constantly fresh for comfortable indoor conditions year-round. The house uses rare materials, with a focus on moon-phase felling and natural air-drying of wood. The wooden deck was built using traditional methods by a single craftsman without nails. Wood throughout is carefully chamfered by hand, creating a soft, high-quality space.
The design takes advantage of the west-facing slope to offer beautiful evening views of sunset-dyed mountain ranges, with the crescent moon as a star feature. The ground-floor bedroom intentionally omits insulation in the earthen floor, allowing the earth's heat to gently permeate the room, supplemented by heaters in surrounding thermal bridge areas. Wet areas like the bathroom are surprisingly dry and comfortable, positioned in the "warm part" of the house to resist condensation. The property uses public water supply, main sewer, city gas, and Tokyo Electric Power.
