In a concrete tower the neighbour you hear is usually the one above, walking. At South Flagler House, here is how the building is meant to keep that sound where it starts.
This page is a framework. Whether the building suits you is a separate conversation. Contact the desk at Miami Dossier for the current position on any building we cover.
Voices and music travel through the air; walls and floors are rated for them by STC, the sound transmission class. Footsteps, dropped objects and chairs travel through the structure; floor and ceiling assemblies are rated for them by IIC, the impact insulation class. The Florida Building Code sets a minimum for each between residences, and some luxury towers state higher targets. Ask which figures South Flagler House commits to, and whether they are tested on site or only calculated.

Stone, tile and wood carry impact sound into the slab. Declarations usually require an approved acoustic underlayment beneath any hard floor, and a few require a test once it is laid. Ask what the rule at South Flagler House says, whether the developer’s own finished floors meet it, and whether an owner who renovates must submit the product and its rating to the association before work starts.
South Flagler House: Park Residences (floors 1 to 3): one- and two-bedroom configurations, about 1,800 to 3,000 square feet of interior space, facing the Norton Sculpture Garden; first-floor homes with private outdoor gardens; approximately 80 percent sold.
Some noise comes from the building itself: an elevator shaft beside a bedroom, a trash chute behind a wall, pumps, generators and cooling towers on the roof or the amenity deck. Read the floor plans at South Flagler House for what sits on the far side of each bedroom wall, and ask where the mechanical rooms sit in relation to the lines under consideration.
South Flagler House: Vanishing-edge pool with Lake Worth Lagoon views and private cabanas; 25-metre lap pool, sun-shelf pool, hot tub; sunset terrace; entertainment lounge with catering kitchen; two private dining rooms; wine tasting room with lockers; library and card room; business centre and private offices; fitness centre with Pilates and yoga studios; indoor pickleball; golf simulator; full spa with treatment rooms, salon, vitality pools, ice plunges, steam and saunas; children’s playroom and teen lounge; sports court; media room.
Laminated impact glass usually cuts traffic and boat noise better than ordinary glazing, and a window’s OITC rating measures that outdoor sound. Ask whether the acoustic targets for South Flagler House appear in the construction drawings or only in the brochure, and whether an acoustic consultant reported on them. The desk asks the developer of South Flagler House for the acoustic specification in writing.

We hold no listings and we are not the developer. Contact the desk at Miami Dossier and we will tell you what applies to your situation, what does not, and where we would not proceed.
