Hidden Oaks is a thoughtful SB-9 infill development that transforms an underused, steeply sloped site in Oakland into two lots, each with a large modern home and a secondary ADU, for a total of four residences. Working in collaboration with architect Debra Yau, the design maximizes allowable coverage while preserving the site’s character and tree canopy. Buildings step with the terrain to reduce grading, create view corridors, and form a sequence of outdoor rooms that connect daily life to the landscape.
The architecture is contemporary and warm. Expansive low-e glazing captures filtered light and long views, while deep overhangs, screened balconies, and planted terraces temper heat gain and add privacy. Dramatic double-height spaces and open stair cores bring daylight deep into the homes and set the stage for flexible living. Renewable, natural materials anchor the palette, with durable cladding and interiors selected for low toxicity and long life.
Sustainability is embedded from the start. Solar-ready or solar-installed roofs, electrification, high-performance envelopes, and water-wise strategies support resilient, low-energy living. The result is a small neighborhood that feels native to its hillside setting, delivering much-needed housing with a light touch and a modern sensibility.
