Home/Where we build/Westlake Village
Custom home builder in Westlake Village, with an office on Lindero Canyon Road.
Ground-up custom homes, additions and whole-house remodels across the Conejo Valley: Westlake Village, Agoura Hills, Oak Park, Thousand Oaks and Bell Canyon. Addition Building & Design is a family-run design-build firm with forty years as a builder and a second office here.

Westlake Village
The west end, from an office at the west end.
Westlake Village is where the valley opens out: lake lots, gated hillside streets, the canyons that run toward Malibu, and a community that sits across the Los Angeles and Ventura county line. Building here means knowing which county's building department your lot answers to, which HOA reviews the drawings, and how the hills around the lake sit in the fire maps. We keep an office at 5776 Lindero Canyon Road so those conversations happen close to the site.
Mike Ross holds the license, signs the contract, settles the design with our design partners, has it engineered by our structural engineers, pulls the permit and walks the site. Christine Ross runs the business. Four to five projects a year, because that is how many the family can personally be present for.
The work here
The Conejo Valley and the canyons beside it.
Calabasas, a few exits east
Five thousand square feet in the Mediterranean tradition, with a home theater and a study.
Pool house and outdoor room
The accessory building a Conejo Valley lot has room for, done as part of the house.
Modern farmhouse, Santa Monica
The same language as Bell Canyon, on the other side of the hills. Our Westlake Village kitchen and the Moorpark hillside addition are on the same list.
What a Westlake Village project involves
Three things we settle before we price.
Which county, which HOA
Westlake Village straddles the county line, and the two sides answer to different building departments. Many streets add an HOA architectural review on top. We confirm your lot's path in the feasibility review, before the design is drawn to the wrong rulebook.
The hills and the fire maps
The slopes around the lake, the canyons toward Malibu and the whole of Bell Canyon are wildfire country. California's wildland-urban interface standard applies, and hillside lots bring grading and access questions we have answered across Los Angeles. How we build to the code.
The house you have
Much of the Conejo Valley was built in the seventies and eighties on generous lots, and a second floor, a kitchen addition or a whole-house remodel is often the right answer. Our structural engineers read what the house can carry before we price it.
A family firm
You get the people whose name is on the firm.
You work with the family that owns the company, on site, through every phase. A builder with forty years in Los Angeles, a daughter carrying the firm forward, and one phone number: 310.617.2722.
Our Westlake Village office: 5776 Lindero Canyon Road, Suite D446, Westlake Village, CA 91362. Both offices
Questions Conejo Valley families ask us
The answers before you commit.
Yes, at 5776 Lindero Canyon Road, Suite D446. It is our second office, and it serves the Conejo Valley: Westlake Village, Agoura Hills, Oak Park, Thousand Oaks and Bell Canyon.
It does for permits. The Los Angeles County side and the Ventura County side of the community run through different building departments, and many streets sit in an HOA with its own review. We confirm which offices your lot answers to before we price.
The Bell Canyon modern farmhouse, our featured project; a Westlake Village kitchen; a gated hillside addition and outdoor living in Moorpark; the Calabasas Mediterranean a few exits east. The work.
The hills around Westlake Village and the whole of Bell Canyon are wildfire country and California's wildland-urban interface standard applies. We design to it from the first sketch.
We walk the property first, then build a line-item, fixed scope, tell you when that price locks, and put every change in writing before it happens. How we build.

Private Consultation
Begin with a conversation.
We take on a select number of significant projects each year. If you are considering a custom estate, a hillside build, or a full transformation, we would be glad to walk the property with you.
