Proven ADU floor plan optimized for efficiency and livability

Proven by Design

Our core floor plans are the result of years of real-world builds — engineered for efficiency, code compliance, and smooth approvals across Southern California.

Designed Around Your Property

Every lot has unique constraints and opportunities. We analyze access, setbacks, utilities, and natural light to unlock layouts that work better — not just on paper, but in real life.

Tailored to How You Live

When a property allows for it, we transform the standard footprint into something uniquely tailored to your lifestyle, whether it’s family, rental income, or long-term comfort.
