Custom Home Builders in Santa Monica, CA
Luxury design-build homes crafted for one of the Westside’s most architecturally vibrant cities, one integrated team, from first concept to final detail.
Santa Monica is a city of tight lots, active streets, and high design expectations. Building well here means navigating urban density with the same level of care that goes into every architectural decision, maximizing light and space where the site offers little room for error, working fluently within Santa Monica’s zoning and massing rules, and producing homes that feel calm and considered in an environment that is anything but.
Westside Build is a luxury custom home builder serving Santa Monica and the wider Westside. Our integrated team — architecture, engineering, and construction under one roof — delivers modern custom homes that are precise, performant, and built to last.
We Know Santa Monica
Santa Monica’s neighborhoods each present a different building context, different lot sizes, different architectural expectations, and different relationships between density and privacy. We have worked across all of them.
NORTH
North of Montana
Santa Monica’s most prestigious residential address: wide streets, generous lots by city standards, and a quiet, tree-lined character that rewards architecture that is refined rather than assertive. Home to some of the Westside’s most significant custom residences. Architectural sensitivity and design quality are both evident here.
Mid-City Santa Monica
A transitional neighborhood between Montana Avenue and Wilshire Boulevard with a mix of lot sizes and architectural styles. A strong market for custom rebuilds and modern new construction where density and design ambition meet in the same block.
SOUTH & COASTAL
Ocean Park
A bohemian, design-forward neighborhood south of Pico with a coastal character and a community that appreciates architectural originality. Smaller lots demand spatial intelligence; homes here succeed through proportion and detail rather than scale.
Sunset Park
A family-oriented neighborhood with bungalow roots and increasing appetite for modern custom homes. Generous by Santa Monica standards, with lots that offer genuine scope for ground-up construction without the premium of Montana or the density of Ocean Park.
EAST
Pico Neighbourhood
One of Santa Monica’s most culturally diverse and evolving areas, a neighborhood in transition, with growing interest from developers and owner-builders drawn by relatively accessible entry points and strong long-term fundamentals.
Wilshire/Montana Corridor
The stretch between Wilshire and Montana combines walkability, architectural variety, and some of the city’s most active renovation and rebuild activity. Mid-century homes alongside contemporary infill, all within walking distance of Montana Avenue’s shops and restaurants.

Why Westside Build for Santa Monica
Building a custom home in Santa Monica is an exercise in precision. The lots are smaller, the neighbors are closer, the zoning rules are more complex, and the community's architectural expectations are genuinely high. There is very little room for the kind of mistakes that happen when design and construction are managed by separate teams with separate accountability.
Westside Build’s integrated model was built for exactly this environment. Because our architects and builders work from the same model from day one, every decision about massing, setbacks, height, and material takes full account of what the site allows and what the city requires, before a permit is filed, not after. Our supply chain ownership and digital twin process protect your budget and timeline in a market where delays and change orders are expensive. And our experience across Santa Monica’s neighborhoods means we know the permitting environment, the architectural review processes, and the logistics of building in a dense urban setting without disrupting the neighborhood you are building in.
