The Residences at Six Fisher Island occupies the last major waterfront parcel on Fisher Island, the roughly 216-acre private island reachable only by ferry, yacht, or helicopter and home to ZIP code 33109, consistently ranked the highest-income ZIP in the United States. Developed by Related Group with BH Group, Teddy Sagi, and Wanxiang America RE Group and designed by Kobi Karp Architecture with interiors by Tara Bernerd & Partners, Six Fisher Island delivers 50 estate-style homes across roughly 10 stories on a 6.5-acre site fronting approximately 650 feet of Biscayne Bay shoreline. Layouts run from about 3,872 to over 9,000 interior square feet across three to eight-bedroom plans, with reported pricing from $30 million for entry homes climbing toward $90 million for a penthouse ask that drew industry attention as one of the highest-per-foot listings in South Florida history. Related Group and partners broke ground on Six Fisher Island in September 2024. The Six Fisher Island site sits at the end of a barrier island accessed by a dedicated car ferry from MacArthur Causeway, with no bridges to mainland Miami Beach or Downtown. Daily life on the island revolves around the historic Vanderbilt Mansion, the Fisher Island Club marina, Spa Internazionale, the P.B. Dye-designed nine-hole championship golf course, 16 tennis courts featuring all four Grand Slam surfaces plus five pickleball courts and two padel courts, and a beach club fronting one of the country's only truly private beaches. Ownership at the Six Fisher Island residences includes Fisher Island Club membership, plus a dedicated golf cart per home for moving between the beach, marina, and clubhouse, since golf carts are the preferred mode of transport on the island. Residence features at the Six Fisher Island project include private elevator entry, 10-foot ceilings, floor-to-ceiling glass, 15-foot-deep wraparound terraces, custom Sub-Zero and Wolf kitchens, and private pools and outdoor kitchens on select home plans. The Six Fisher Island amenity program covers more than 55,000 square feet, including two resort-style pools, a sanctuary spa with hot and cold plunges, a fitness center and yoga studio overlooking Biscayne Bay, a padel court, a residents-only bayfront restaurant, house car and tender service to neighboring islands and Miami Beach, and 24-hour butler and concierge staffing.
