Location
The Island Sanctuary of Key Biscayne
A barrier-island village of extraordinary privacy — fifteen minutes from Brickell, a world away from everything else.
Privacy & Exclusivity
A single causeway, village-scale governance, and strict zoning keep Key Biscayne quiet, secure, and intentionally under-built — a genuine enclave minutes from a global city.
Beaches & Nature
Miles of Atlantic beach are bookended by two treasured parks: Crandon Park to the north and Bill Baggs Cape Florida State Park — repeatedly ranked among America's best beaches — to the south.
15 Minutes to Brickell
The Rickenbacker Causeway delivers you to Brickell's financial district, Coconut Grove, and Miami International's private aviation terminals in minutes — without living amid the density.
Boating & Marina Lifestyle
Surrounded by Biscayne Bay and the Atlantic, the island offers world-class boating, sailing at the Key Biscayne Yacht Club, and quick runs to the sandbars and out islands.
No State Income Tax
Florida levies no state income tax and no state estate tax — a decisive factor for buyers relocating from New York, California, Illinois, and abroad.
School Quality
Families are drawn by highly rated village schools including MAST Academy nearby and access to Miami's top private schools — Ransom Everglades and Carrollton are minutes away in Coconut Grove.
Why the Island Stays Scarce
Key Biscayne's supply is structurally constrained: the island is nearly fully built out, the village enforces conservative zoning, and no new oceanfront condominium has been delivered in over a decade. For UHNW buyers, that scarcity is the point — 301 Ocean Drive represents the rarest kind of opportunity, a new building in a market that almost never produces one.
The Geography of the Island
Key Biscayne sits roughly seven miles off mainland Miami, a barrier island reached by a single road — the Rickenbacker Causeway. Crandon Park occupies the northern third of the island with two miles of protected beach, a championship tennis center that hosted the Miami Open for decades, a public golf course, and a marina. Bill Baggs Cape Florida State Park anchors the southern tip around the 1825 Cape Florida Lighthouse. Between them lies the Village of Key Biscayne: about 1.25 square miles of residential streets, oceanfront condominiums along Ocean Drive, and a small commercial village center.
301 Ocean Drive occupies 3.8 acres of that oceanfront corridor — one of the last assemblages of its scale on the island, and the reason the site commanded $205 million.
Boating, Beach & Club Life
The island's waterfront life runs in two directions: the Atlantic on the east side for swimming, paddling, and beach days, and Biscayne Bay on the west for boating, sailing, kiting, and fishing. The Key Biscayne Yacht Club, the Ocean Club, and the historic Crandon Park Marina put deep water minutes from the front door, with Stiltsville, the sandbars, and the upper Keys within an easy cruise.
Schools, Services & Governance
The Village operates its own police and fire-rescue departments, community center, and parks system — a level of local control that residents consistently cite as the reason the island feels different from Miami proper. Key Biscayne K-8 Center and MAST Academy serve island families, while Ransom Everglades, Carrollton School of the Sacred Heart, and Gulliver Prep are a short drive across the causeway.
Taxes & Residency Considerations
Florida imposes no state income tax and no state estate tax, and the Homestead Exemption plus the Save Our Homes assessment cap can meaningfully limit annual property tax growth for primary residents. Buyers relocating from high-tax states or from abroad should confirm residency timing and structure with their own tax counsel — the numbers frequently drive the purchase decision as much as the residence itself.
Key Biscayne Living: Buyer Questions
How long does it take to get from Key Biscayne to Brickell or the airport?+
Brickell is roughly 15 minutes across the Rickenbacker Causeway, Coconut Grove about 12 minutes, and Miami International Airport about 25 minutes outside peak traffic. Private aviation at Miami Executive and Opa-locka is 30–40 minutes.
Is Key Biscayne a good place to live year-round with a family?+
Yes. The Village of Key Biscayne is a residential municipality with its own police, fire, and parks departments, a community center, and highly rated public schooling, plus quick access to Miami's leading private schools in Coconut Grove.
What does daily life on the island look like?+
Life is walkable and low-key: a grocery-anchored village center, a compact restaurant scene, tennis at Crandon Park, golf at the Crandon course, beach clubs, and boating from the island's marinas — with Miami's dining and culture 15 minutes away.
How does the island handle hurricanes and flood resilience?+
Key Biscayne is a barrier island, so new construction is engineered well above current code: elevated habitable floors, impact glazing, hardened building systems, and elevated back-up power. 301 Ocean Drive is planned around climate-resilient standards from the ground up.
Why does Key Biscayne real estate stay so scarce?+
The island is effectively built out, the Village enforces conservative height and density limits, and no new oceanfront condominium has been delivered in over a decade. New supply is the exception, not the norm.
