Design + build under one roof.
Our architects, engineers, and builders collaborate daily, aligning layout, structure, and constructability in real time. Permit-ready plans reduce corrections and keep momentum.

Decisions first, materials secured early.
We mapped long-lead items (windows/doors, roofing, electrical, plumbing, cabinets) and placed early POs. Value-engineering options and clear specs minimized change orders and protected the budget.

Raised, resilient, and compliant.
Finished floors were set 1 ft above BFE, with foundation detailing for durability. Title 24, CALGreen, electrical and plumbing upgrades bring the entire project to current code.

Space for living, working, and hosting.
The main home is remodeled for better flow; the attached two-story ADU adds a full kitchen, bath, bedroom, and living areas. New garage, covered carport, decks, stucco, windows, and roofing complete the transformation.
