Room Additions in Hermosa Beach
Room additions are their own discipline — different from a remodel and different from an ADU. We integrate the new framing, foundation, roof, and finish so the addition disappears into the original architecture instead of looking glued on.
Hermosa is small lots and big constraints. Walk-street and Strand-adjacent homes pack a lot of house onto a little footprint, so every inch of an addition or ADU has to earn its place.
Building in Hermosa Beach
We know the local ground.
Tight setbacks, strict height limits, and Coastal Zone review across much of the city mean the design has to be right before you ever pull a permit. We feasibility-check the envelope first.

Frequently asked
Common questions.
Do you take on additions projects in Hermosa Beach?
Yes. Hermosa Beach is squarely in our South Bay service area, and additions work is one of our core services. Tight setbacks, strict height limits, and Coastal Zone review across much of the city mean the design has to be right before you ever pull a permit. We feasibility-check the envelope first.
How much addition can we add to our lot?
Depends on the city, the lot, the FAR, and the setbacks. We'll do a feasibility read before you commit to drawings — usually a same-day answer after a site walk.
Can you match the existing house?
Yes — that's most of the job. Matching trim profiles, siding, roof pitch, and window proportions is what makes an addition feel original instead of bolted-on.
How long does a typical addition take?
Plan on 4–8 months of construction once permits are issued, depending on size and whether the existing house stays occupied during the work.
