The home should be
the treasure chest of living.
ZZA exists to build that chest — pairing certified global supply chains with Northern California's finest craftsmanship, so every residence and ADU we deliver holds a life worth keeping. Led by California Licensed Architect Annie Wu.
Leave the complexity.
Keep the architecture.
We design residential sanctuaries for Bay Area families who demand timeless spatial balance without navigating municipal friction alone. Translating California codes, Title 24, setback allowances, and structural coordination into seamless architectural execution.
A backyard sanctuary,
built to statutory perfection.
Detached backyard cottages, garage transformations, and junior suites. Purpose-engineered around California Gov. Code § 65852.2 to maximize 4-foot rear setbacks, 1,200 sq ft allowances, and transit parking exemptions.
Details you feel
before you notice.
Floor-to-ceiling thermally broken aluminum fenestration, warm cedar louvers, honed travertine countertops, and custom architectural joinery. Fully coordinated with California Title 24 energy envelopes for effortless daylight and climate performance.
Room to grow.
Rooted where you are.
Ground-floor footprint expansions, second-story master wings, and structural open-concept conversions. Keep your preferred neighborhood and schools while reimagining daylight, circulation, and modern spatial volume.
Navigating California codes,
transparently.
Every municipality across Silicon Valley and San Francisco enforces distinct zoning overlays, historic envelopes, and utility connection mandates. Principal Architect Annie Wu liaises directly with building officials to accelerate approval.
