Stick-Built Addition
YOUR LOCAL ROOM ADDITION CONTRACTOR
A Smarter Room Addition for Huntington Beach Homes
In a coastal city where moving up usually means paying a lot more for a bigger house, many Huntington Beach families decide to build on instead. A conventional stick-built addition means framing, roofing, drywall, and months of crews working at your house. A pre-engineered sunroom or patio room addition delivers comparable usable space, whether it's a home office, playroom, gym, or expanded family room, typically at 50-70% less cost and with far less disruption.
Lot sizes vary widely across HB, from compact Downtown parcels to the larger lots of Edwards Hill, so setbacks and lot coverage shape what you can build. We check those at your free in-home consultation, confirm the foundation, and take the project through the City of Huntington Beach's Building & Inspections division. If your address is in the Coastal Zone, we also handle the coastal review. Walk through full-size rooms at our Buena Park showroom before you decide.

ADDITION TYPES
Room Addition Options for Huntington Beach Homes
You don't have to frame and drywall a new room from scratch. Here's how Huntington Beach homeowners add space with us, usually for far less than a conventional build.
Four-Season Sunroom Additions
A fully insulated glass room tied into your home that heats and cools like any other room. It's the closest match to a conventional addition, at a fraction of the cost. Learn more on our Huntington Beach sunrooms page.
Patio Room Additions
Turn your existing slab into a comfortable solid-roof room for a playroom, guest space, or den. See our Huntington Beach patio rooms.
Home Office Additions
A bright, quiet workspace separate from the main living area, so video calls don't compete with the TV or the kids.
Family Room & Dining Expansions
Extend a family room or kitchen dining area into the backyard, with glass walls that bring in the coastal light.
Solid-Roof Additions
Insulated EPS roof panels and C-Thru wall systems create a quiet, energy-efficient addition that looks and feels like part of the original house.
Permitted & Warranty-Backed
Every addition is permitted through the City of Huntington Beach and carries a transferable lifetime manufacturer warranty, which helps at resale.
