Custom Homes & New Construction in Newport Beach, CA
Building a new home means coordinating an architect, engineers, the city, utility companies and many trades over a long schedule.

How it works
From Design To Build
- 01
Preconstruction
We review the plans, or help you assemble a design team if you do not have one yet, and give input on cost, buildability and schedule while changes are still easy to make on paper.
- 02
Permits and approvals
We handle permit applications and city coordination. In coastal cities, approvals can include coastal or design review in addition to the building permit, so they are mapped out early.
- 03
Construction
Site work, foundation, framing, roofing, rough systems, inspections and finishes, in that order. We schedule and coordinate the trades, inspections and material deliveries throughout.
- 04
Walkthrough and closeout
Before handover we walk the house with you, record anything that needs attention on a punch list and complete it. Final inspection sign-off from the city closes out the permit.
FAQ
Frequently Asked Questions
Early, ideally while the architect is still developing the plans. A builder can flag details that are costly or difficult to build and give cost feedback while changes are still inexpensive to make.
We are a general contractor, not an architecture firm. We work with trusted architects, engineers and interior designers, and we also build from plans by the architect you have already hired.
Every new home needs a building permit from the city's building department, which includes plan check against the building code and local zoning. Much of Newport Beach, Corona del Mar and Laguna Beach lies within California's Coastal Zone, where a coastal development permit can also apply, and Laguna Beach has its own design review process. Which approvals apply depends on the lot, so it is one of the first things to confirm.
The schedule has two parts: design and approvals, then construction. The first depends on the city and on which reviews apply to your lot. The second depends on the size and complexity of the house and on material lead times. We build the schedule from your plans and do not quote a generic range.

Kitchen Remodeling
A kitchen remodel involves more trades than any other room in the house: demolition, framing, plumbing, gas, electrical, ventilation, cabinetry, countertops, tile and finish carpentry. Siemonsma Construction manages that work as the general contractor, from coordinating the design and handling permits through to the final walkthrough, so one company is responsible for the sequence and the result.

Bathrooms are small rooms with a lot happening behind the walls. Supply and drain lines, waterproofing, ventilation, electrical and tile all have to be right, because mistakes show up later as leaks and moisture damage. Siemonsma Construction runs bathroom remodels as the general contractor, from design coordination and permits through construction and the final walkthrough.

Whole-Home Remodeling
A whole-home remodel is closer to building a house than to updating a room. Structure, mechanical systems, layout and finishes are all in play at once, and the order in which the work happens matters. Siemonsma Construction is a general contractor with more than 40 years of experience in custom remodels and new construction, and manages each project from the first plans through the final walkthrough.
