Home Additions in Los Angeles
Add a bedroom, expand your kitchen, or build a second story. We design and construct home additions that match your existing home across Los Angeles.
A well-designed home addition lets you stay in the neighborhood you love while adding the space your family actually needs. Whether that's an extra bedroom, a larger primary suite, an expanded kitchen, or a full second story, the goal is the same: more usable space that feels like it always belonged.
We handle everything from architectural design and structural engineering to permits and full construction. Our team coordinates with the city, manages subcontractors, and keeps you informed at every milestone so you're never guessing about schedule or cost.
Because additions tie into existing framing, foundations, and utilities, we spend time up front to make sure rooflines, siding, and interior transitions look intentional — not bolted on. The finished result should look like one home, not two.

How it works
Financing available
Homeowners may consider a HELOC, cash-out refinance, or construction loan. Financing is offered by third-party lenders and is subject to lender approval, rates, terms, and availability. Build Construction is not a lender.
