There are listings that stop you in your tracks.
When I first walked the grounds of 3149 Brickell Avenue
in Coconut Grove, I already knew the neighborhood well — intimately, in fact. But standing at the water's edge, 170 feet of Biscayne Bay stretching out before me, the downtown Miami skyline shimmering in the distance, I felt that rare clarity that only the fi nest properties produce. This was not just a home. This was a place that defines a city.
I'm proud to share that this extraordinary 1.61-acre bayfront estate is now listed at $110,000,000 — and that the listing has already captured national attention, with coverage in the Wall Street Journal, Robb Report, and The Real Deal.
What Makes 3149 Brickell Ave Unlike Anything Else on the Market
Miami has no shortage of luxury properties. But true scarcity — the kind of irreplaceable combination of acreage, water frontage, elevation, and location — that is extraordinarily rare.
3149 Brickell sits atop Silver Bluff, one of the highest natural bayfront elevations in Miami-Dade County. In a city where flood resilience and long-range views are increasingly prized, this is not a minor detail. It is a defining feature. The gated estate unfolds across a sweeping private drive lined with mature tropical landscaping, opening to a three-story residence originally constructed in 1920 — 5,705 square feet of interior space across seven bedrooms and five baths, with a total footprint of 8,356 square feet.
An extended dock reaches toward the bay. The views are unobstructed. The privacy is complete.
This stretch of Coconut Grove along Brickell Avenue was once known as "Millionaire's Row" — and for good reason. Estates here have always commanded a premium precisely because they cannot be replicated. The parcel at 3149 Brickell represents one of the widest waterfront lots currently available anywhere in Miami-Dade County.
When I say this is a generational offering, I mean it in the most literal sense. Properties likethis don't come back to market. They are held, cherished, and passed on. The question isalways simply: who is the right steward for the next chapter?
A Market I Know Deeply — And the Record That Proved It
If you follow Miami real estate closely, you may already know my name from another chapter in this same story.
In 2022, I had the extraordinary privilege of representing the sale of the Adrienne Arsht Estate — the neighboring bayfront estate at arshtestate.com — which closed at $106,875,000. That transaction marked the first residential sale in Miami-Dade County history to surpass the $100 million threshold. It wasn't just a record. It was a signal to the world that Miami had arrived as a global ultra-luxury market — on par with the most coveted addresses in Manhattan, London, or the Côte d'Azur.
I'll be honest: closing that deal required everything. Years of relationship-building. Deep knowledge of the global buyer pool for properties at this tier. An understanding of what motivates ultra-high-net-worth individuals when they consider a purchase at this scale — not just the metrics, but the emotion, the legacy, the lifestyle. There is no formula for it. It requires genuine expertise, patience, and an unwavering commitment to presenting a property as the singular opportunity it truly is.
The Arsht Estate sale didn't just make headlines. It reset the benchmark for what Miami waterfront is worth.
And now, with 3149 Brickell Avenue, we are writing the next chapter.
Why Miami's Waterfront Will Continue to Appreciate
I've been selling Miami luxury real estate for decades. I've watched this market evolve from a regional story into a global one. And I can say with conviction: the waterfront in Miami is among the most valuable real estate in the world — and it is becoming more so.
Here's why:
Supply is finite. The bay is not growing. The natural elevations along Silver Bluff cannot be engineered elsewhere. There are only so many bayfront parcels of this scale in Miami-Dade County, and fewer still with this combination of acreage, frontage, privacy, and proximity to Brickell's financial district, Vizcaya, and the cultural heart of the city.
Demand is global and accelerating. Miami continues to attract wealth from Latin America, Europe, the Northeast United States, and increasingly from Asia. The buyers I work with are not speculating — they are choosing Miami as their primary or secondary home, drawn by quality of life, favorable tax environment, and a city that has matured into a world-class financial and cultural center.
Ultra-luxury is its own category. At the $100 million-plus tier, buyers are not comparison-shopping in the traditional sense. They are seeking irreplaceable assets. The Arsht Estate sale proved that Miami buyers exist at this level. 3149 Brickell will prove it again.
What It Takes to Represent Miami's Most Significant Properties
People sometimes ask me how I came to specialize in Miami's most significant waterfront estates. The honest answer is that it has always been about relationships and trust — and about doing the work.
When a seller trusts you with a $100 million property, they are entrusting you with something that took a lifetime to build. That weight is not lost on me. It is why I invest in understanding every detail of a property's history, its architectural character, its land story, and the unique audience of buyers who will recognize its value.
It is why the Arsht Estate sale — Miami's first $100 million-plus residential transaction —required not just marketing expertise, but a global network, discretion, and the patience to find exactly the right buyer for an irreplaceable asset.
And it is why 3149 Brickell Avenue deserves — and is receiving — the same caliber of representation.
