Home Additions in Bay Harbor Islands
Room to grow on a finite island.
Families move to Bay Harbor Islands for the town itself — quiet streets, the walk to Ruth K. Broad Bay Harbor K-8, water at the end of the block — and then discover their 1950s West Island house has two bedrooms and one opinion about closet space. The addition is how you stay. A second story over the original footprint, a rear extension toward the canal, a garage turned guest suite: on a small island where single-family land is finite, building up or back usually beats moving out.
Additions here get looked at properly. Plans go through the Town of Bay Harbor Islands Building & Zoning Department, and additions and exterior changes are reviewed by the town's Design Review Board before permits issue. On a barrier island, FEMA's substantial-improvement rule matters too: when the value of the work approaches half the value of the house, flood-elevation requirements can reshape the whole project, so it is far better to run that math in design than to discover it in review. Add hurricane engineering for the new structure, and you want a contractor fluent in all three conversations.
PGX has been building additions in South Florida for over 20 years under license CGC1539072, and the ones that succeed are engineered before they are pretty: tie-beam upgrades, new footings where a second story lands, connections detailed so the old house and the new one behave as one structure. You get a fixed written scope, a schedule built around your family actually living there, and a supervisor on site every day watching the tie-in — the seam where additions are won or lost.

What's included
Ways to add on here.
Five proven paths to more room on the West Island, each engineered, town-reviewed, and built to read as original.
Up over the original footprint
A full upper floor over the original footprint, with tie-beam upgrades, reinforced footings, and stairs placed where the plan wants them.
Extending toward the canal
Living space extended toward the canal or bay with engineered structure and setbacks respected — the view finally invited inside.
Guest and in-law suites
Garage conversions and attached suites with their own baths, built for parents, long-stay guests, or the year both arrive at once.
Foundation and structural work
Footings, columns, and connections engineered so old structure and new addition carry load as one building, not two acquaintances.
Invisible tie-ins
Rooflines, stucco textures, and floor levels matched carefully enough that visitors cannot find where the original house ends.
