William Duff Architects, Inc. — Portola Valley, CA, 2023

Golden Oak Residence is a 4,529 square foot house completed in 2023 by William Duff Architects, Inc. in Portola Valley, California. Set on a hilltop site, the project responds to its rural surroundings with a layout that distinguishes between public and private zones, providing both spaces for gathering and areas for retreat. The design introduces a butterfly roof that enhances natural light, ventilation, and sightlines from the main living spaces toward the landscape. A shift in the building's plan geometry marks the transition between communal and private areas, supporting a sense of calm and separation within the residence. The selection and placement of materials are structured to create visual order while adding warmth, referencing the textures found in the immediate environment.
