Architect Kendrick Bangs Kellogg began building the Wingwalk House for an artist couple who commissioned him almost a decade ago. Access to the home is achieved only via an electrical car. The garage is literally tucked into the mountain. Except for the construction of the driveway, the design managed not to disturb the landscape as the home was built around existing boulders. Kellogg chose concrete because of its adaptability to freeform design and for its insulating qualities. The house's nickname, Wingwalk, comes from the wing-like appearance of the home's canopies. Inside, there are none of the normal vertical separations commonly known as walls, just boulders that divide spaces. The main part of the house is an artist's studio. All the windows and doors in the house are unique, some featuring Jurassic-themed designs etched into the earthquake-sensitive tempered glass. Ribbons of rusted steel separate the studio tables. The massive chimney serves as a fireplace on one side and a built-in couch on the other. All of the cabinetry features rusted and treated steel that's made to look like bronze. The floors look like tile but are actually sliced rock pieces arranged in a mosaic pattern. The master bedroom, situated near an incline, is the perfect spot for a waterfall.
