Home Additions in Bal Harbour
Growing a house behind the gate.
Nobody is making more land in Bal Harbour. The village was master-planned in the 1930s and essentially built out decades ago, which means owners on Bal Cross Drive or Bal Bay Drive who love their street but not their square footage have one real option: build onto the house they have. Rear extensions toward the garden, second stories that capture bay views, and garage conversions into guest or staff quarters are the projects we see most, often as part of a larger renovation.
An addition is exactly the kind of project the Village of Bal Harbour reviews hardest. New construction and additions require Architectural Review Board approval and a Certificate of Appropriateness before the Building Department issues a permit, and the design has to respect setbacks, lot coverage, and the character of a very tidy village. Then come the technical layers: High-Velocity Hurricane Zone engineering, foundations and tie-beams designed for coastal wind loads, and, in AE flood zones, FEMA substantial-improvement math that can determine whether an ambitious addition triggers elevation requirements for the whole house.
Additions are where a general contractor either coordinates or improvises, and improvisation shows. PGX runs additions with the structure decided on paper: engineered drawings, a fixed written scope, and a schedule that sequences foundation, shell, tie-in, and finishes so the existing house stays livable and dry. Deliveries are timed for narrow gated streets, a supervisor walks the site each day, and the crew that ties the new roof into the old one is the same crew accountable for the warranty. That is what one team from estimate to closeout actually means.

What's included
Addition work we take on.
Every addition below starts with engineering and the Village's design review, not with a sledgehammer and a sketch.
Extensions toward the garden
Family rooms, bigger kitchens, and glass-walled living space extended toward the garden side of the lot, matched to the existing structure.
Second floors for the bay view
New upper floors engineered from the foundation up — often the only way to gain a bay view on a built-out street.
Garage and wing conversions
Underused garages and side wings turned into guest quarters or in-law suites, with the permits pulled rather than the corners cut.
Tie-beams for older masonry houses
Reinforced tie-beams, columns, and connections that let older masonry houses carry new loads safely and legally.
Footings for coastal soil
Footings and slabs designed for coastal soil and flood-zone requirements, verified by inspection before anything rises above grade.
