Love your neighborhood but out of square footage? An addition is almost always less disruptive and less expensive than moving. We design additions that match your existing rooflines and finishes, handle the engineering and permits, and tie the new space into your home's systems cleanly.
Ground-floor additions
Primary suites with en-suite baths and walk-in closets, expanded kitchens and great rooms, home offices and in-law suites. We match stucco texture, siding profile, roof pitch and window style so the addition disappears into the original home.
Second-story additions
When the lot is tight, we go up. A second-story addition can double your living area while preserving the yard. The process includes a structural evaluation of the existing foundation and framing, engineered plans, temporary weather protection, and careful sequencing so the family can often remain in the home for most of the build.
Zoning, setbacks and permits
Every addition is checked against lot coverage, setbacks, height limits and, where applicable, hillside or HPOZ rules before we draw. We coordinate architectural and structural plans and manage plan check with LADBS or your local building department.

How long does a second-story addition take?
Design and permitting commonly take three to five months, and construction another five to eight months depending on size. We publish a milestone schedule before the first day of work.
