A large round hole allows a glimpse through the white wall in front of this California home. auxiliary living spacedesigned by architect Yan M. Wang of Cover Architecture for his mother.
The Los Angeles based architect built an additional apartment on his property in Altadena, north of Pasadena, so his mother and her partner could be closer to family after retirement.
The 620-square-foot (57-square-metre) building was built between the main house and the street and split into two to make room for a walkway to the rear of the property.
The living quarters are located in the larger part on the right, and the storage rooms are in the narrow volume on the left. Both rooms are completely white.
The minimalist form was deliberately designed to “challenge” the 1961 ranch-style, single-story home where Van and his young family live.
“This deliberate contrast of styles and building eras represents the interplay of the ordinary and the extraordinary,” said the architect.
The ADU's living volume is partially concealed by a wall that rises from the walkway and includes a circular portal punched through at the higher end.
This feature gave the project the name “Moongate”, after the round gates found in traditional Chinese architecture.
“Its distinctive slanted partition with a large circular opening both conceals and reveals what lies beyond the parapet,” Wang said.
The wall creates a shaded terrace in front of the house, which serves as an outdoor seating area, secluded from the street.
The curved eaves elements of the roof and the arched entrance to the storage space help to perceive the two volumes as a single whole.
Inside the modest building there is a kitchen and living room, a bedroom, a bathroom and a small office.
“Cheerful geometric forms are evident throughout both the exterior and interior of the ADU, as well as in the palette of light, natural materials,” the architect said.
Baltic birch plywood cabinetry with round pulls used throughout is complemented by light gray Pietra Artica marble used for the kitchen counter and onyx marble above the bathroom vanity.
Skylights in the kitchen and bathroom provide additional natural light to these areas, and the rear terrace overlooks the courtyard shared with the main house.
“These three structures, in dialogue with each other, help to strengthen the sense of connection with nature, bringing together three generations and providing enough space for shared interactions as well as for retreating to secluded areas,” Wang said.
ADUs have grown in popularity in states like California and Texas, where revised zoning laws allow for higher housing densities in urban and suburban areas.
Others in California include mountain home in marin county with a wooden interior and an attic, as well as Bay Area Residential Complex consisting of two pedimented volumes connected by a glazed bridge.
