Near the crest of a hill overlooking the Pacific sits a small, sublime architectural adventure. Its boxy exterior, a windowless facade of steel and stucco, seems to recede into the landscape. But surprises start at the massive front door — an 8-by-9-foot stainless steel slab opens electronically, like a bank vault. Inside, floors of inky blue steel, set like stone in 2-by-6-foot plates, meet walls of oiled hemlock. An entire ocean-facing wall of glass disappears when its panels fold up to the ceiling. And then there’s the master bedroom, which also functions as the master bath, its focal point a glow-in-the-night tub that is a hand-cast resin sculpture. The house is profoundly personal, shared minimalist vision of landscape architects Abbie and Bill Burton and their architect Jennifer Luce, who won two American Institute of Architects awards for it in May. “What we're passionate about, along with Jennifer, is design from the essential elements. The raw character of the material is in full view, in its natural form, not covered by anything else,” Bill Burton says. In Luce, 47, Canadian-born with a Harvard design degree, the couple found an artist who heeded the spirit, not just the specifics, of what they wanted. The Burtons, who live with their two teenagers and a Bernese mountain dog, bought the 1970s, two-storey house seven years ago. “It looked frightening at first.Really odd big bedrooms, black walls, mirrors everywhere,” Bill Burton says. But the couple agreed it had potential. “It had a great ocean view, great basic form. The flat-roof shell was what we were attracted to. And we loved the upside-downness of it.”
