Home Additions in Miami Beach
Growing a house on a regulated island.
Lots in Miami Beach are finite in a way that concentrates the mind, so when a family outgrows a house on Pine Tree Drive or a Sunset Islands lot, the answer is usually up or back rather than out of the neighborhood. We build rear extensions that open 1930s and 1950s homes toward pool and bay, second-story additions over strengthened first floors, garage conversions, and guest suites for the in-laws who visit every winter and stay longer each year. Done well, an addition reads like the house always intended it — that is the standard we permit and build to.
If Miami Beach regulation has a reputation, additions are why. The City of Miami Beach Building Department reviews structure, zoning checks lot coverage and setbacks, and the FEMA substantial-improvement rule sits over everything: if your project's value crosses the fifty percent threshold, the whole house must meet current flood elevation standards, including the city's freeboard requirement above base flood elevation. In historic districts, the Historic Preservation Board expects additions to stand politely behind the original facade. None of this is a reason not to build; it is a reason to design with the rules in the room from day one.
Structure is the quiet half of every addition here. Second stories on pre-war masonry mean tie-beam upgrades, new columns, and foundations verified before anyone talks about finishes; PGX brings the engineers in early and prices that work into a fixed written scope instead of discovering it at month three. Our 20-plus years in South Florida and 150-plus delivered projects taught us to sequence additions so the family keeps living in the house while it grows. Daily supervision, protected interiors, and one accountable license from first sketch to final inspection — that is the whole pitch.

What's included
How we build additions on the Beach.
Additions here are equal parts architecture, engineering, and paperwork. This is the work we plan, permit, and build.
Family rooms toward the water
New family rooms and primary suites extending toward pool and water, tied into the existing structure with engineered footings and connections.
Upper floors over reinforced masonry
Full upper floors over reinforced first stories, with engineering, tie beams, and stairs placed where the plan wants them rather than where they merely fit.
Garage and loggia conversions
Turning underused garages and loggias into offices, gyms, or guest quarters, with the insulation and cooling that make them genuinely livable in high summer.
Guest suites for long winters
Self-contained suites with baths and kitchenettes where zoning allows, designed for long visits that stay pleasant on both sides of the guest room door.
Tie beams for pre-war masonry
Structural upgrades that let older Miami Beach masonry carry new loads, verified by engineers, inspected by the city, and hidden by the finish work.
