If you are searching for mansions on Fisher Island Miami, you have come to the right place. Fisher Island is one of Miami’s most coveted addresses — a private barrier island accessible only by private ferry, yacht, or seaplane. As a result, the average property value here consistently ranks among the highest in the United States. Now, for the first time in decades, developers are completing a collection of brand-new private island estates there. The Mansions on Fisher Island are priced from $32M to $55M. Indeed, they represent an entirely new standard for luxury real estate in Florida.

Whether you are exploring Fisher Island real estate for the first time or you have been watching this market for years, The Mansions deserve your full attention. There are only a handful available, and one has already sold.

Fisher Island: A Private Island with a Storied History

Fisher Island sits just off the southern tip of Miami Beach, separated from the mainland by Government Cut — the shipping channel that runs alongside South Beach. In the 1920s, William K. Vanderbilt II purchased the island and built a grand Mediterranean-style winter retreat, which still stands today as the historic Vanderbilt Mansion. Through the 1930s, ownership changed hands several times before the island ultimately evolved into one of the world’s most exclusive private residential communities.

Today, zip code 33109 — Fisher Island’s postal code — regularly appears on lists of the wealthiest zip codes in the country by per-capita income. Notably, the island has no public access whatsoever. In fact, every visitor and resident arrives by private ferry, private boat, seaplane, or helicopter. That level of controlled access is a defining feature of the lifestyle. Furthermore, it is part of what makes Fisher Island real estate so rare and so sought after on a global level.

At the heart of community life sits the Fisher Island Club — a members-only institution anchoring island culture. Its amenities include the original Vanderbilt Mansion, the Beach Club on the Atlantic side, Spa Internazionale, and private marinas. Additionally, golfers enjoy exclusive access to The Links at Fisher Island, a 9-hole championship course designed by P.B. Dye, featuring pristine Paspalum fairways, artfully placed lagoons and bunkers, and two sets of tees.

The Mansions on Fisher Island Miami: What Is Being Built

Developed by MADAR Group USA — the American arm of the family-owned MADAR Group founded over 50 years ago by Raoul Madar — this project is led by Alain Madar as Partner and Group CEO, and David-Emmanuel Cohen as CEO of MADAR Group USA. With a portfolio spanning luxury properties across Europe, the Caribbean, and the United States, MADAR Group brings an institutional-grade development standard to a project that is anything but typical. Architecture is by the acclaimed Miami firm Portuondo Perotti Architects, working in collaboration with ASR.

Drawing from a Tuscan-inspired Mediterranean aesthetic, the design language emphasizes warm stone facades, arched loggias, and deep terraces that blur the boundary between indoor and outdoor living. Every detail reinforces a sense of timelessness over trend — an approach entirely consistent with the ethos of the island itself.

Site Layout and Available Inventory

Specifically, the site sits alongside The Links golf course, nestled within the island’s most exclusive enclave. In total, there are 12 lots, each oversized and private, with its own pool, landscaping, outdoor kitchen, and pergola. The mansions for sale range from approximately 8,500 to 15,800 square feet of interior living space. Similarly, lot sizes range from 13,200 to 23,400 square feet. Importantly, these are not condominiums. Rather, these are true private island estate homes — freestanding, fully detached, and entirely private.

Current available inventory includes:

Mansion	Price	Interior SF	Lot SF	Bed/Bath/Powder
Mansion No. 3	$36.5M	10,648 SF	15,949 SF	8 BD / 10 BA / 2 PR
Mansion No. 4	$36.5M	10,648 SF	15,670 SF	8 BD / 10 BA / 2 PR
Mansion No. 5	$36.5M	10,977 SF	16,166 SF	6 BD / 7 BA / 2 PR
Mansion No. 7	$55M	15,802 SF	23,400 SF	8 BD / 10 BA / 2 PR
Mansion No. 9	$32M	8,570 SF	13,242 SF	6 BD / 7 BA / 2 PR

Each home delivers fully finished construction, including a finished pool, complete landscaping, outdoor kitchens, pergolas, pavers, and an elevator. All interior and exterior doors, garage doors, and flooring are also included. Beyond that, bathrooms and kitchens come fully furnished and equipped with appliances — not as an upgrade, but as a standard delivery. Select residences target a move-in ready completion in October 2025, at the level of a turnkey luxury hotel suite rather than a builder-grade spec home.

The Fisher Island Lifestyle and Club Amenities

Life on Fisher Island operates on a different cadence than the rest of Miami. There are no tourists, no traffic, and no unsolicited visitors. Because the permanent population is kept intentionally small, roads remain quiet and beaches stay clean and uncrowded. Residents and club members travel the island by golf cart. As a result, the pace here is deliberately unhurried — and that is exactly the point.

Fisher Island Club Amenities and Recreational Facilities

The Fisher Island Club provides members with access to a world-class amenity package. Perched on the Atlantic shore, the Beach Club offers private beach access, cabanas, and food and beverage service. Spa Internazionale provides a full range of wellness and beauty treatments. Meanwhile, the Racquet Club features 18 courts with all four Grand Slam surfaces — hydro Har-Tru, deco turf, grass, and red clay. It also includes a pro shop, professional instruction, four new pickleball courts, and padel courts. The private marinas can accommodate large vessels and provide easy access to the Bahamas and beyond.

Golfers also enjoy exclusive access to The Links at Fisher Island — a P.B. Dye-designed 9-hole course ranked among the most exclusive golf experiences in South Florida, complete with Paspalum fairways, artfully placed lagoons, two sets of tees, and the Greenside Golf Grill. Beyond golf, multiple dining venues and private event spaces round out what amounts to a fully self-contained community at the highest level of luxury.

For buyers considering Miami Beach luxury real estate more broadly, The Mansions on Fisher Island offer something no condo tower can replicate. In particular, they offer total ground-level privacy, your own private outdoor estate, and the complete absence of shared walls or shared elevators.

Who Is Buying These Fisher Island Mansions for Sale

Buyers pursuing mansions on Fisher Island Miami come from a global pool of high-net-worth individuals seeking a primary or secondary residence. A private island address, a European-quality construction pedigree, and pricing from $32M make this a natural comparison point not against other Miami properties, but against estates in Monaco, Saint-Barthélemy, Sardinia, and the Hamptons.

Many buyers in this price range want a Florida base that combines privacy, security, and genuine estate-scale living — a combination historically difficult to find in South Florida outside of Indian Creek Island. That gap is precisely where The Mansions on Fisher Island step in. Additionally, private ferry access means the island functions as a true gated environment, not merely a gated street.

Investment Context: Why Zip Code 33109 Still Commands a Premium

Others are drawn by the island’s history and cachet. After all, Fisher Island has been home to some of the world’s most notable private residences for nearly a century. Therefore, The Mansions represent the first entirely new estate-scale construction on the island in a generation. That scarcity is real and it is permanent.

If you are comparing this to Miami Beach waterfront homes or other ultra-luxury Miami properties, it is worth considering the investment thesis. Specifically, properties in the 33109 zip code have consistently commanded a premium relative to comparable square footage anywhere else in South Florida. Moreover, new-construction mansions on the island have no comparable recent comp — which is itself a significant factor.
