Home Additions in Surfside
Room to grow between the ocean and the bay.
Families who land in Surfside tend to stay, held by the beach, the walkable town center on Harding Avenue, and the short list of places like it. What gives out first is the house: a 1940s footprint with three modest bedrooms and no office. On compact lots between the ocean and Biscayne Bay, the answer is usually to build rather than sprawl, whether that means a rear extension into the yard, a garage converted properly, or a second story that finds light and breeze the original architect never went looking for.
Additions get the town's full attention. Plans go through the Town of Surfside Building Department and before the Planning and Zoning Board for design review, with setbacks and lot coverage checked closely on streets this compact. Structural work must meet Miami-Dade's High-Velocity Hurricane Zone standards, meaning new foundations, tie-beam connections, and roof tie-ins engineered and inspected, and on older low-slab homes FEMA's substantial-improvement accounting can shape how a project is phased. None of it should scare you off; it should convince you to settle the sequence before anything gets poured.
PGX has delivered more than 150 remodels and additions across South Florida in twenty-plus years, and additions are where that experience pays twice, once in engineering and once in logistics. We tie new structure into old without leaving a scar, protect the occupied half of the house while we build the new half, and keep a supervisor on site daily. The scope is fixed in writing through drywall, finishes, and the final inspection, so the addition ends the way it started: on purpose.

What's included
Ways to add space in Surfside.
Five proven paths to a bigger house on a beach-town lot, each one engineered, permitted, and built to match the original home.
Second floors above a low roofline
Full upper floors over reinforced postwar structure, adding bedrooms and breeze-catching terraces where a low roofline used to be.
Extending the house into the yard
Family rooms, dens, and enlarged kitchens extended into the yard on new foundations, tied into the existing slab and roof correctly.
Carports rebuilt as living space
Carports and garages rebuilt into conditioned living space: insulated, permitted, and finished so nothing about the room says garage anymore.
Guest quarters with a kitchenette
Self-contained guest quarters with a bath and kitchenette, built for the long family visits South Florida households actually host.
Tie-beams and HVHZ connections
Tie-beams, columns, and foundation work engineered for the High-Velocity Hurricane Zone, because new structure is only as good as its connections.
