Earlier this year, tech billionaire Mark Zuckerberg and his wife, Priscilla Chan, made headlines when they dropped $170 million on an unfinished estate on the ultra-exclusive Indian Creek Island, often dubbed the "Billionaire Bunker." Meanwhile, a sprawling waterfront compound in Key Biscayne with a prominent Hollywood pedigree—having famously starred in the classic film Scarface—hit the market with an astronomical asking price of $237 million. Further inland, the music superstar The Weeknd also staked his claim in the local luxury market, dropping $50 million for a sprawling mansion within the exclusive Gables Estates neighborhood.
Yet, even against the backdrop of these eye-watering sums, a new listing in Coral Gables threatens to shatter local benchmarks and redefine the upper limits of property values in the area. Another magnificent residence within the prestigious Gables Estates enclave has officially listed for an astonishing $148 million. If the property manages to fetch anywhere near its asking price, it will nearly triple the current residential sales record for Coral Gables, which currently stands at a relatively modest $55 million by comparison. Dennis Carvajal of ONE Sotheby’s International Realty holds the exclusive listing for the expansive estate.
Gables Estates stands as one of the most elite, tightly guarded residential communities in the entire Miami metropolitan area. Comprising fewer than 200 homes and lots, the neighborhood is celebrated for its oversized waterfront parcels that offer direct, bridge-free navigation out to the sparkling waters of Biscayne Bay. Over recent years, property values within this private enclave have surged dramatically, with historic sales climbing well into the tens of millions of dollars. Today, multiple active listings in the neighborhood command asking prices of $50 million or more, yet none approach the sheer scale of the Arvida Lane offering.
Spanning approximately 2.4 prime acres at the peaceful terminus of a private lagoon, the newly listed estate commands an impressive 245 feet of deep-water frontage. Boating enthusiasts will find the property particularly compelling, featuring a roughly 90-foot dock designed to accommodate substantial vessels. Crucially, because there are no fixed bridges separating the property from Biscayne Bay, watercraft enjoy seamless, uninhibited access to the open ocean—a rare and coveted amenity even among Miami’s elite waterfront properties.
Architecturally, the main residence is a grand European Revival-style masterpiece envisioned by renowned architect Rafael Portuondo. The home spans more than 14,000 square feet of meticulously crafted interior living space, accommodating six bedrooms, nine full bathrooms, and three half-baths. Upon entering the residence, guests are greeted by dramatic 25-foot ceilings that anchor a double-height living room, illuminated by natural light pouring through expansive arched windows and centered around an opulent crystal chandelier. The interior finishes showcase a sophisticated blend of rich wood and polished marble flooring, complemented by extensive architectural detailing throughout the sprawling floor plan.
Beyond the formal living spaces, the residence is equipped with a comprehensive suite of luxury amenities designed for high-end entertaining and everyday leisure. These include a dedicated wine room, a fully appointed bar, a private home theater, a spacious billiards room, and dual executive offices tailored for private business operations.
The primary suite serves as a private sanctuary within the estate, featuring its own integrated sitting area, a private outdoor terrace, a convenient wet bar, two expansive dressing rooms, and a lavish bathroom finished primarily in rare onyx. For hosting visiting guests or extended family, the property offers a separate, self-contained guest villa connected via a covered loggia. This standalone structure includes its own independent living and dining areas, alongside a fully functioning kitchen. Health and wellness enthusiasts are similarly catered to by a detached waterfront gym facility, which is complemented by an adjacent sun deck and a private hot tub.
Perhaps one of the most distinctive features of the estate is its inclusion of a private, consecrated-style chapel, complete with custom woodworking and intricate stained-glass windows. Stepping outside, the meticulously landscaped grounds unfold into a tropical paradise. The exterior features a mosaic-tiled swimming pool, expansive marble terraces designed for outdoor dining and lounging, and a fully equipped summer kitchen. The botanical landscaping is equally breathtaking, boasting more than 600 distinct species of palms, mature trees, and rare botanical specimens that provide total privacy and natural beauty.
The estate’s ownership history adds another layer of local prestige. The property belongs to Manuel Diaz, the founder and president of Manuel Diaz Farms. Diaz originally acquired the land back in 2002 for $6.4 million. Following the acquisition, he commissioned architect Rafael Portuondo to design the current residence, which was ultimately completed in 2007.
The estate is no stranger to the luxury real estate market, having experienced a series of strategic listing attempts over the years. It first debuted on the market in 2017 with an asking price of $45 million. As market conditions in South Florida evolved and luxury demand surged, the asking price was progressively adjusted upward, hitting $55 million in 2018, $48.5 million in 2020, and $52 million in 2021 before the property was eventually withdrawn from the market in 2022.
The decision to relaunch the property at $148 million represents a massive leap, instantly positioning it among the most expensive residential properties ever publicly marketed in Miami-Dade County. It also highlights a broader transformation across the wider Miami real estate landscape. Market data indicates that the greater Miami area now features at least five single-family residential properties publicly listed above the $100 million threshold, a dramatic increase from just a single property matching that criteria in 2022. Whether this ambitious nine-figure asking price successfully attracts a buyer willing to rewrite the record books for Coral Gables remains one of the most closely watched storylines in luxury real estate.
