Your lot still has room left.

South Miami real estate math is simple: the location, wedged between Coral Gables, Pinecrest, and the Metrorail, is superb, and the houses are smaller than the families in them. Across Red Road in High Pines and Ponce-Davis, the answer is usually a teardown. Inside the city, in Bird Road Estates, Cocoplum Terrace, and Twin Lakes, owners tend to keep the house and grow it instead: a rear extension into the deep lot, a second story over the original footprint, a garage turned into the office or suite the 1950s never planned for.

Additions live or die on the site plan. The City of South Miami's Land Development Code sets the setbacks and lot coverage that define your buildable envelope, the Building Department reviews the structural package, and exterior design can go before the city's Design Review Board. One local wrinkle worth respecting: any permit that requires a survey also requires a tree location plan from a licensed professional, because this city takes its canopy seriously. We confirm all of it — envelope, trees, board requirements — before you spend real money on design.

An addition is structural work first and architecture second, which is why PGX starts with the engineering: can the existing foundation and tie-beam carry a second story, or do they get upgraded before anything goes up? From there it's the discipline you'd expect from a contractor with 20-plus years in South Florida — a fixed written scope, daily supervision, new construction made weathertight fast, and the occupied half of your house kept livable and clean. When it's done, the addition should read as if the house was always this size.
