Home Additions in Hillsboro Beach
Growing a house between two waters.
Land is the scarce thing in Hillsboro Beach. The town holds roughly a third of a square mile of dry ground, strung along one road, and nobody is making more of it. So owners on Hillsboro Mile expand what they have: a rear wing toward the Intracoastal, a second floor over a low 1960s ranch, a garage turned into a guest suite, a conditioned room where a screened porch has been slowly losing its argument with the salt. Estate lots that run from the beach across A1A to a private dock have room in the middle. Most of the work happens there.
Additions here are a zoning exercise before they are a construction one. The Town of Hillsboro Beach reviews site plans at the commission level, and a complete set of drawings is expected two months ahead of the meeting it is calendared for. The code caps most buildings at three stories and thirty-five feet, measured above average dune elevation east of A1A and above the crown of the road on the west side, and holds an 85-foot front setback. Runoff has to stay off A1A, mechanical equipment has to be screened, and oceanward work can fall under the state's coastal construction control line.
Experience on an addition either shows or is conspicuously absent. Tying a new foundation to a fifty-year-old one, matching stucco texture and roof profile so the seam disappears, keeping the occupied half of the house livable and clean while the other half is open to the sky. PGX has delivered more than 150 remodels and additions across South Florida, every one permitted and inspected. We fix the scope in writing, we run the site daily, and we carry the project from the first feasibility conversation through final inspection and warranty without handing you off.

What's included
Where an oceanfront lot has room.
Every one of these starts with a survey, a structural opinion and a clear read of the town's standards. Then we draw.
Building toward the Intracoastal
Family rooms and primary suites extended toward the Intracoastal side, with footings, beams and the roof connection drawn as a single engineered package.
Second floors, structure first
An engineer evaluates existing block, footings and tie beams before anything is drawn, then the upper floor is designed to the three-story cap the code allows.
Converting the garage properly
Bringing garage and covered space into the conditioned envelope with insulation, impact openings and permitted mechanical work an appraiser can count.
Guest and staff suites
Private quarters with a shower bath and small galley for visiting family or house staff, scaled to the architecture rather than bolted onto the back of it.
Elevation and flood work
Raising finished floor, reworking foundations and detailing flood openings where base flood elevation or a substantial improvement determination puts the house into current standards.
