A private gated island community in Aventura — 84 acres of waterfront luxury, nine residential towers, and a world-class private club.
Williams Island is one of South Florida's most coveted private residential communities — an 84-acre island in Aventura, completely surrounded by the waters of Biscayne Bay. Accessible only through a single guarded entrance, the island offers a level of security, privacy, and exclusivity that is rare even by Miami standards.
Nine residential communities — seven high-rise towers and the Mediterranean Village townhomes — line Island Boulevard, each with its own character and price point. What unites them all is access to the same extraordinary shared infrastructure: a private marina, a five-star spa and fitness club, multiple restaurants, retail, and 24/7 concierge services.
For buyers, understanding the island means understanding that the choice is not just about a unit — it is about which building's position, size, and character best matches your lifestyle.

Every resident on Williams Island — regardless of which building they choose — pays the same island-wide fees: POA dues ($980/month), Club membership ($1,500/year), annual minimum spend ($2,000), and a one-time initiation fee ($15,000).
On top of that, each buyer must budget for their building's own monthly maintenance fee — which is separate and varies based on the building's size, age, number of units, amenities, and location on the island. This is the number that changes from building to building, and from unit to unit within the same building.

Each building on Williams Island has its own character, price point, and position. Use the quick-jump below or scroll through each building's profile.
The first tower you encounter upon entering the island, the 1000 Building offers the most accessible price point in the community. Its prime position near the island entrance means residents are steps from the shops, restaurants, and services of Williams Island Boulevard.

The 2000 Building strikes an ideal balance between size, location, and value. Larger floor plans than the 1000 Building make it popular with buyers seeking more living space, while its mid-island position offers convenient access to both the entrance amenities and the quieter northern end.

The Mediterranean Village is Williams Island's only low-rise community — a collection of townhome-style residences with Mediterranean-inspired architecture, private garages, and lush garden courtyards. Located near the island entrance, it offers a distinctly different lifestyle from the high-rise towers while sharing all island amenities.

Every resident on Williams Island shares access to a private club that rivals the finest five-star resorts in South Florida. These facilities are exclusively for residents and their guests — never open to the public.
The Williams Island Club includes approximately 70 group fitness classes per week, a full-service spa with massages and facials, steam room, sauna, hot and cold plunge pools, and an indoor lap pool. House guests receive complimentary passes — a rare perk that makes entertaining on the island effortless.



Buying on Williams Island means understanding two distinct layers of cost. First, there are the island-wide fees that every resident pays, regardless of building — these cover the POA, the Club, and the initiation fee. Second, there is your building-specific monthly maintenance, which is added on top and varies depending on your building's size, age, number of units, and location on the island. Here is a complete breakdown of every cost a buyer should expect.
* Building maintenance shown is for a ~3,000 sf unit in the 3000 Building. Your actual maintenance will depend on your specific building and unit size. All other fees (POA, Club, Min. Spend) are the same island-wide. Electricity not included.
Disclaimer: All fees and amounts shown are for informational purposes only and are subject to change. Maintenance fees vary by unit and building. Buyers should verify all costs with the building association and their attorney prior to purchase. Information provided by Elsa Rozenberg, Keller Williams Luxury Real Estate.
