In a move that underscores the growing global appetite for ultra-luxury Florida real estate, Concierge Auctions has confirmed that bidding is now live at $13 million for a sprawling new-construction estate on Longboat Key — a property originally listed at $38.45 million. The auction house announced that the seller’s reserve has been met, clearing the way for the sale to conclude live in London this November.

The estate, designed by the internationally recognized firm Sweet Sparkman Architecture & Interiors, rises on nearly two private Gulf-front acres. It is being marketed in cooperation with Joel Schemmel of The Schemmel Soda Group at Douglas Elliman Real Estate. The sale will be the highlight of Concierge Auctions’ London Global Sale, held on 20 November at The Connaught in Mayfair, an event that will feature a curated selection of luxury properties from across North America and Europe over two days. Concierge Auctions will oversee the process.

“This is a visionary estate with the scale and ambition to command attention on a global stage, making it an ideal fit for our auction platform,” said Chad Roffers, CEO and Co-Founder of Concierge Auctions. “There is tremendous opportunity here for a buyer to take an already exceptional vision and make it distinctly their own. Bringing the property to auction and closing live in London allows us to showcase that opportunity before an international audience and generate the level of competition a property of this caliber deserves.”

“What makes this property so compelling is not simply its scale, but what Sweet Sparkman has envisioned within it,” said Schemmel. “From the expansive Gulf-facing living spaces and sweeping terraces to the private beach, guest accommodations, and resort-style amenities, every element has been conceived around the way someone wants to live and entertain on Longboat Key. The next owner has the opportunity to take an extraordinary design and finish it around their own lifestyle.”
While the home is substantially realized, it remains a new construction project with approved architectural plans for completion. The finished residence will span more than 32,000 total square feet, featuring 11 bedrooms, 13 full bathrooms, and four half bathrooms. Positioned to capture uninterrupted Gulf views, the property pairs sweeping terraces and private beach access with the flexibility for the future owner to shape the final expression of an architecturally significant estate. Plans call for a dramatic foyer that opens into an expansive great room overlooking the Gulf, while the primary suite will include dual spa-inspired bathrooms and bespoke dressing rooms. Multiple guest suites and a guest-level kitchenette round out the accommodations.
Designed to accommodate both large-scale entertaining and everyday living, the home will include a showpiece entertaining kitchen and a separate chef’s kitchen, a formal dining room, a temperature-controlled wine cellar, an office, a lounge, and a private cinema. A detached guest house and a separate pool house offer additional privacy and flexibility for guests or staff. Outside, the resort-style grounds will feature a pool and spa, expansive terraces, water features, and layered landscaping that leads to the private beach. A rooftop deck will capture panoramic coastal views, and the plans allow for the potential addition of a private tennis and pickleball court. An attached seven-car garage completes the property.
Longboat Key, a barrier island stretching between Sarasota Bay and the Gulf of Mexico, is known for its 12 miles of white-sand beaches, waterfront recreation, golf, and resort living. The property sits minutes from The St. Regis Longboat Key Resort and The Resort at Longboat Key Club, with shopping and dining at nearby St. Armands Circle. Approximately 10 miles away, downtown Sarasota offers cultural destinations including The Ringling, Sarasota Opera, and the Van Wezel Performing Arts Hall, while Sarasota Bradenton International Airport is about a 30-minute drive.

Why it matters: This auction represents a significant test of the global luxury market’s appetite for Florida waterfront properties, with the $13 million opening bid offering a steep discount to the original $38.45 million list price. The outcome could signal whether high-net-worth buyers see current conditions as an opportunity to acquire trophy assets at a potential bargain, or whether even prime Gulf-front estates require new pricing strategies to close. For the broader market, it underscores how auction platforms are increasingly used to bring urgency and international exposure to properties that might otherwise languish in traditional listings.
