$40 Million West Palm Beach Penthouse Lists Two Years Before Completion
Realtor.com · Kellie Speed · 24 August 2026

TL;DR
A 10,190-square-foot full-floor penthouse atop the under-construction Maison d'Or building in West Palm Beach, Florida, has been listed for $39.7 million — roughly two years before the building is expected to be completed in Q4 2028. Groundbreaking is scheduled for later in 2026. Developed by Kolter Urban, the 19-storey boutique tower will house just 39 residences along South Flagler Drive. The penthouse occupies the entire 19th floor, offering four bedrooms, 11-foot ceilings, floor-to-ceiling glass, panoramic waterfront views, a wine tasting room, wellness spaces, a game room, butler's pantry, and a staff suite. The developer is targeting high-net-worth buyers relocating from the US Northeast or California, as well as Palm Beach residents seeking a second home.
Our take
This listing is firmly outside the South African property market, but it carries a few lessons worth noting for local luxury developers and high-net-worth buyers. First, off-plan sales at this price point — listing nearly two years before completion — signal strong confidence in a pre-sales model that SA developers in Cape Town's Atlantic Seaboard and Sandton's luxury corridor have also leaned into. The boutique approach (39 units, full-floor privacy, curated amenity mix) mirrors what is gaining traction in developments like those along De Waterkant and Umhlanga Rocks Drive, where discerning buyers are moving away from large-scale towers toward intimate, design-led buildings. For South African investors with offshore allowances, US luxury pre-sales remain a consideration, though rand-dollar exposure and SARB foreign capital rules apply. Closer to home, the trend of targeting 'downsizing estate owners who won't compromise on quality' is directly relevant to agents working the R20m-plus segment in Constantia, Fresnaye, and Sandhurst — buyers who want lock-up-and-go convenience without sacrificing space or lifestyle.
