    Private sanctuaryPrivate loggiaOutdoor kitchenPool deckDual islandsAbundant natural lightBright breakfast room
    A striking new construction estate, set for completion early summer 2026, 40 Cardinal Lane offers refined coastal living on an oversized lot and a half in Sunrise Cay. Designed with timeless Palm Beach flair and built to the highest standards, the home seamlessly blends elegance with comfort. A gracious entry leads to a dramatic two-story living room with coffered ceilings and abundant natural light. The main living spaces feature custom millwork, stone flooring, and a fireplace, all opening seamlessly to expansive covered outdoor areas designed for year-round enjoyment. The chef's kitchen is a true centerpiece with dual islands, premium appliances, custom cabinetry, and a bright breakfast room. A pantry, mudroom, and elevator add to the home's thoughtful design. The first-floor primary suite is a private sanctuary with a spa-like bath, dual showers, freestanding soaking tub, inlaid marble flooring, and generous his-and-her closets. A private loggia opens directly to the pool deck. Upstairs, four spacious guest suites with ensuite baths offer comfort and privacy, along with a quiet reading nook and an oversized sun deck capturing sweeping ocean views. Lagoon views from the first floor create a tranquil setting, while the second floor enjoys elevated ocean vistas. Outdoor living is exceptional with a resort-style pool and spa, outdoor kitchen, and multiple covered terraces with cypress ceilings. The backyard features private putting and chipping greens, creating a golfer's retreat. Floating dockage behind the home allows convenient access to both the bay and ocean. Additional highlights include a large finished garage and exceptional craftsmanship throughout.
