Philip Johnson’s Glass House may be the golden standard for transparent living, but that hasn’t prevented other architects from making their own statements in glass. Architects Leslie and Julie Dowling, who completed this California home in 2012, made full use of the eight idyllic acres on which the house sits by encasing the living and dining areas in floor-to-ceiling glass. Concrete floors and wood ceilings that extend beyond the glass to the outside patios keep the house’s square footage flexible and fluid. “Creating efficient space is valuable, but for us, rooms that offer visual and spatial continuity with nature are also important,” Julie Dowling explains. “When the sliding doors are open, the living room and kitchen double in size.” Now, that’s a glass act even Philip Johnson may have envied.
