The square footage you are missing.

Nobody adds a wing to the 40th floor. Additions in Sunny Isles Beach happen on the single-family streets west of Collins Avenue, where Golden Shores fills the blocks between 186th and 191st Streets, and gated Atlantic Isle rings its own island with waterfront lots. The originals are mostly two- and three-bedroom houses from the 1950s and '60s — modest footprints on land whose value outgrew them decades ago. Owners who love the location extend toward the canal, go up a story, or convert the garage into a suite rather than trade away a bay view for square footage elsewhere.

Additions run through the City of Sunny Isles Beach Building Department, with structural plans, energy calculations, and Miami-Dade product approvals filed through the city's digital portal; larger projects also get Planning and Zoning attention before a permit is issued. On this barrier island, FEMA flood-zone math shapes the design itself: push an older house past the substantial-improvement threshold and the entire structure must meet current elevation rules. Setbacks, lot coverage, and seawall proximity on Atlantic Isle all get resolved on paper first, which is considerably cheaper than resolving them in the field.

An addition is structural work pretending to be lifestyle work, and PGX treats it that way: foundation assessment before promises, tie-beam and roof connections engineered to current wind code, and a written scope that fixes what the new square footage includes before the first saw cut. Your existing house stays livable and protected while we build. One licensed, insured team — CGC1539072, 20-plus years in South Florida — carries design coordination, permits, inspections, and warranty from start to finish.
