David MacNeil is quietly dismantling his luxurious South Florida property empire — and replacing it with something far more grand.
The billionaire WeatherTech founder and CEO unloaded his waterfront Fort Lauderdale estate at 84 Isla Bahia for $34 million, and the deal was done in less than 21 days, The Post has learned.
The buyer’s identity hasn’t surfaced in public records.
The transaction is the latest move in a sweeping real estate repositioning by the car mat billionaire, who has been quietly trading coastal Florida trophy properties while assembling what may become one of the most ambitious private compounds on the Eastern Seaboard.
Spread across three levels and just over 11,700 square feet, this just-sold six-bedroom residence sits on a point lot inside the guard-gated Harbor Beach community, commanding nearly 300 feet of Intracoastal frontage.
Inside there are soaring ceilings, marble and wood floors, four fireplaces, six wet bars, a commercial-grade elevator and a third-floor lounge that opens to sweeping water views.
Outside sits a roughly 90-foot infinity-edge lap pool, sun terraces and a private dock with direct ocean access. The community also offers residents a private beach club, with Las Olas dining and yachting just minutes away.
Listing agent, Chad Carroll of the Chad Carroll Group at Compass, called it a textbook execution. Brett Bass of Bass Realty and Investments represented the buyer.
“In this market, buyers move quickly on properties that check every box,” Carroll told The Post.
The Fort Lauderdale sale is essentially the closing chapter of MacNeil’s life on the lower Gold Coast and the opening act of something much larger to the north.
Over the past two years, MacNeil has spent roughly $94 million assembling a rare ocean-to-Intracoastal assemblage in Manalapan, a small barrier island town 10 miles south of Palm Beach that has quietly become a magnet for the ultra-wealthy.
He picked up a 2-acre lot for $38.5 million in April 2024, then added an adjacent 1.5-acre parcel last May for $55.5 million in cash, buying it from celebrity developer Joe Farrell, whose clients have included Madonna and Justin Bieber.
The combined site spans roughly 3.6 acres with 340 feet of ocean frontage, and sits on land where only Mar-a-Lago in nearby Palm Beach shares the same ocean-to-Intracoastal configuration.
MacNeil wasn’t shy about his view of the deal. “I actually think I got a bargain,” he told The Post last year.
He has since listed the vacant assemblage at a whopping $125 million and is planning a full-scale compound on the site. A structure of up to 60,000 square feet could theoretically rise there, though all plans require town approval.
