Developers Kolter Urban and Perko Development Partners have unveiled a $39.7 million full-floor penthouse at Maison d’Or, their 39-unit boutique condominium at 3705 South Flagler Drive in West Palm Beach, PROFILEmiami reported August 25, 2026. The 10,190-square-foot residence occupies the entire 19th floor — roughly $3,900 per square foot. The listing lands as a fresh pricing marker for the stretch of waterfront that has drawn a wave of ultra-luxury development — the corridor at the heart of our coverage of West Palm Beach’s luxury new developments.
What does $39.7 million buy at Maison d’Or?
Per PROFILEmiami’s August 25 report, the crown residence spans 10,190 interior square feet across the full 19th floor, with four bedrooms, six full bathrooms, and three powder rooms under 11-foot ceilings. Floor-to-ceiling glass and expansive terraces frame the Intracoastal Waterway, the Atlantic, Palm Beach Island, and the West Palm Beach skyline, with both sunrise and sunset exposure.
The building around it is deliberately intimate: 39 residences across 19 stories, designed by 10 Design with interiors by Hirsch Bedner Associates and landscaping by EDSA, in a Mediterranean-and-Regency vocabulary reinterpreted for contemporary Palm Beach, per PROFILEmiami. Amenities include an elevated waterfront pool deck, private dining and entertaining spaces, a cocktail bar and wine-tasting room, wellness and treatment areas, a screening theater, a virtual sports simulator suite, and a dedicated dog spa. When sales launched, The Real Deal reported January 8, 2026 that pricing began at $5.7 million for residences of 3,000 to more than 10,000 square feet, on the 1.4-acre former Flagler House site.
Why does this listing matter for the West Palm Beach market?
A near-$40 million ask at a boutique 39-unit building signals that developers now see Palm Beach Island-caliber penthouse pricing migrating across the Intracoastal. For buyers, it sharpens the calculus on South Flagler Drive, where scarcity — not scale — is the product: full-floor plates, private-club amenity ratios, and low unit counts.
Buyers weighing a contract here should note that boutique buildings concentrate operating costs across few owners — our guide to HOA fees at luxury new developments explains how to model that — and that pre-completion purchases still warrant standard diligence on deposit structure and the contract terms. International purchasers eyeing the penthouse tier should start with our foreign buyer’s guide to South Florida luxury condos.
