Nestled on Turtle Bale Walkway and positioned in Alys Beach's most exclusive enclave of true gulf-view homes, this extraordinary custom home, masterfully designed by Khoury Vogt, redefines coastal luxury. Commanding stunning gulf views from three floors over Turtle Bale Green, this architectural masterpiece blends Old World artistry with contemporary sophistication. Vibrant accents in teal, seafoam, and emerald greens, pale pink, and light blue complement Venetian plaster walls and exquisite, fully custom wood finishes, creating an exclusive, elevated living experience. The first floor welcomes you through a striking iron pivot door into an octagonal entry rotunda, wrapped in custom wood paneling and floored with large Paris Casa limestone. A breathtaking suspended wood staircase frames views of the coveted ground-level private pool and loggia. Additionally, this level features a fountain-facing bedroom with a view of the iconic walkover. A charming bunk room, a full bath, a half bath, an elevator, and an air-conditioned two-car garage with carriage-style doors and Christiana cabinetry, designed with room to install two lifts, accommodating a total of four cars. Ascending to the second floor, the heart of the home unfolds into an open-concept living area framed by a seafoam-green wood-floating ceiling and adorned with luxurious Minotti furniture. The main area flows effortlessly from the state-of-the-art Bulthaup kitchen, equipped with premium Gaggenau appliances, to the large balcony overlooking the gulf. The formal dining room, enveloped in a strikingly elegant blue Venetian plaster, is separated from the main space by a custom glass partition, while a cozy inglenook conversation area invites intimate gatherings while staying connected to the main areas. A guest master suite and powder bath complete this level. The third floor houses the opulent primary suite, a serene retreat with an oversized private balcony showcasing sweeping gulf views. Its boutique-style Eggersmann closet system, featuring built-in jewelry cases and a private washer/dryer, redefines luxury. Marble-clad bathrooms, illuminated by exquisite old-world chandeliers, elevate the experience, while a second guest master suite ensures ample space for family or guests. Crowning the home, the fourth-floor rooftop deck is an entertainer's dream. Features include a full summer kitchen, conversation fire pit, Minotti outdoor furniture, a bonus dog park, and a panoramic gulf viewing area for morning coffee. Savor sunsets and host unforgettable family gatherings. Premium Loewen fold-away doors offer seamless flow from indoor to outdoor spaces, while vibrant tile accents and a curated blend of classical art, bespoke lighting, and fine art pieces harmonize with modern bath and kitchen decor to create a fun, beach-living experience. Convenience is prioritized with a Control4 smart house system, allowing customizable light, music and drapery scenes throughout. A full-house Culligan water purifier and water leak protection system with auto shut-off ensures peace of mind when away. Experience the harmonious, sophisticated beach lifestyle of 31 Sea Castle Alley. With your ownership comes access to dramatic community pools, a fitness spa, restaurants, a private beach club, and a tennis and pickleball center. Scenic Highway 30A is fast becoming a world-class golf destination to complement its award-winning beaches. This extraordinary proximity to beach access lies just a few steps from your beach retreat.
