Residential Architecture in Orange County
Custom homes and renovations across Orange County, from oceanfront and gated communities to inland neighborhoods, designed around how you live, with one team guiding design, approvals, and construction.
Orange County runs from the oceanfront to established inland neighborhoods, and the way you build reflects where you are. Bluff and gated coastal lots come with community design rules and close review in cities like Newport Beach and Laguna Beach, while inland projects turn on interiors, layout, and how a home lives day to day. We design and manage homes and interiors across both, meeting the local standards so each house belongs to its setting.

Key Considerations for Building in Orange County
Your community’s design review comes first
Many Orange County homes sit in gated or HOA-governed communities like Emerald Bay or Three Arch Bay, where an architectural review board approves exterior work before the city does. We prepare the submission to the community’s standards and material guidelines so the design clears review the first time.
Coastal sites carry their own permits
Oceanfront and bluff lots in Newport Beach and Laguna Beach can require a Coastal Development Permit and face height, setback, and view-protection rules. We map that path early so the design holds up through both city design review and coastal review.
Designing for the view without losing privacy
A coastal home lives by its relationship to the water and the light. We plan glazing, orientation, and outdoor space to open the house to the view while keeping it private and comfortable through the day.
Climate Considerations
Salt air and coastal exposure demand materials and detailing that hold up over time. We specify for the marine environment so the home stays as good as it looks.
How an Orange County project moves forward
Every project moves through the same four phases. In Orange County, the approvals run on two tracks at once, the community and the city, which we manage together so they do not hold each other up.
01
Discovery & Feasibility
We start with the site, the view, and how you want to live, reviewing community design rules, coastal status, zoning, and code before design begins.
02
Schematic Design
Floor plans and 3D models that show how the home will feel, function, and open to the water, view and the outdoors.
03
Design Development, Construction Documents & Permitting
We prepare detailed drawings and permit sets and coordinate with the community’s architectural review board, the city design review process, and the Coastal Commission for coastal sites.
04
Construction Administration & Project Management Construction Administration
Unlike many firms whose involvement ends after permitting, we remain actively engaged throughout construction. We conduct regular site visits, review shop drawings and submittals, respond to contractor questions, and work collaboratively with the construction team to help ensure the design intent, quality, and craftsmanship are maintained through project completion. We believe great architecture is realized during construction, not just on paper. That’s why we remain actively involved through completion, serving as our client’s advocate from the first sketch to the final walkthrough.

Common questions about Orange County projects
Do you handle HOA and community architectural review?
Yes. For homes in gated or HOA-governed communities we prepare the submission to the board’s standards and material guidelines and manage the review so the design is approved without repeated resubmittals.
Can you handle coastal and Coastal Commission approvals?
Yes. For oceanfront and bluff sites we map the Coastal Development Permit path early and design to clear it alongside the city’s design review.
Do you design new coastal homes as well as renovations?
Both. We design new custom homes, teardown-and-rebuilds, and major renovations and additions, and manage each from design through construction completion.
What is included in your interior design services?
Interior design covers FF&E, space planning, and integration within the architecture, so the home is not only well built but fully realized. We source and manage furniture, wall coverings, decorative lighting, accessories, and draperies through installation.
