Introducing House on Kataokayama | Living beneath a large roof spanning the terrace., a custom-built home example by Yoshihiro Yamamoto Architects Associates, a Architect / Design office in 302, Zeniya Honpo Main Building, 14-6 Ishigatsujichō, Tennōji-ku, Osaka
Living beneath a large roof spanning the terrace.
Aerial view from the elevated site.
The reinforced-concrete frame is half-embedded into the hillside to form a high foundation, avoiding a mixed-construction approach.
Nameplate, mailbox and intercom fabricated from steel plate and solid timber.
From the closed entrance to the open-plan living/dining/kitchen. There is virtually no step between the doma (earthen-floor entry) and the LDK.
The LDK features a sloped ceiling that utilizes the main roof. Overall tones are restrained to emphasize the textures of timber and steel.
A large kitchen measuring 6.4 m in length.
The kitchen and back unit are designed to emphasize the horizontal.
The kitchen occupies the best position for cooking while overlooking the entire living area and the views beyond the windows.
View from the dining area toward the entrance. The black wall finish is chalkboard paint.
The wall edge is set back from the corner to secure views toward the Yamato River while imparting a sense of buoyancy to the roof.
A fall-prevention balustrade and stair handrail are integrated as a continuous element crafted from steel flat bar.
Descending the stairs leads to the family's plaza, beyond which is a deck paved with flat concrete slabs.
View back up the stairs from the plaza.
View of the master bedroom from the plaza.
Exterior night view.
LDK at dusk. Indirect lighting concealed in the east and west slit windows provides overall illumination.
Indirect lighting concealed in the triangular slit is dimmable to suit different scenes.

This residence is sited on a terrace that extends from the wide riverbed of the Yamato River. The plot fronts the upper terrace and offers panoramic views over the towns of Ōji and Sangō and the mountain range running from Mount Shigi to Mount Ikoma. From the center of the site the ground drops approximately 3.0 m to a lower terrace, and via a retaining wall it drops a further approximately 4.5 m to the adjacent land. The lower terrace contains the bedroom and closets, functioning as both earth-retaining and an elevated foundation, while the upper terrace secures a broad horizontal plane. The kitchen, stairs and wet areas are distributed across the upper level beneath a large gabled roof, establishing an open, highly circulatory under-eaves space as the focal point of daily life. The gabled roof frames the expansive landscape like a picture, admits daylight and ventilation through narrow side slits, and enables a smooth approach from the parking area. Finishes with restrained materiality and saturation and details with minimal lines reduce the visual presence of the architecture itself, allowing the life lived within and the surrounding panorama to take center stage.
