31 Sea Castle Alley, Alys Beach
MLS® # 1003040
Rising directly from the sand at the coveted east end of 30A, this brand-new Gulf-front estate redefines beachfront living in Inlet Beach. Completed in 2026, designed by Stackable Mracek Design Group and built by Corestruction, the residence spans four light-filled levels and approximately 11,188 square feet, all served by a private elevator. Walls of glass frame the emerald water from nearly every room, while 65 feet of private Gulf frontage place the beach just steps from the door.
Built to endure as beautifully as it impresses, the home features solid stucco-over-block construction on a piling foundation, engineered for coastal living. Inside, the craftsmanship is immediately apparent, with wide-plank white oak floors, honed marble, beamed and coffered ceilings, soaring walls of windows, and designer brass throughout. The main living level centers on a gourmet kitchen with an oversized island, dual refrigeration, and a butler's pantry, complemented by a dedicated wine room and wet bar. From there, the great room flows beneath twelve-foot ceilings onto an expansive Gulf-front covered porch that captures both the breeze and the view.
With 7 bedrooms and 7.5 baths, there is room for the whole family and then some. Five en-suite bedrooms and a custom built-in bunk room ensure everyone has a place to land, while the entertainment offerings rival a private resort. A media and movie room, multiple game rooms, and a dedicated fitness room with sauna and steam cover every age and interest. An indoor-outdoor pool house blurs the line between living space and beachfront leisure, opening directly to the pool deck.
The entire top floor is devoted to a private owner's retreat. Vaulted tongue-and-groove wood ceilings crown a serene bedroom, a sitting room, and a spa-inspired bath with a freestanding soaking tub and dual vanities. A custom dressing room provides generous storage, and a Gulf-front balcony offers a front-row seat to sunset after sunset over the water.
Outdoor living is equally exceptional. A heated gunite pool with a sun shelf and spa anchors the deck, accented by water and fire features, a summer kitchen, and shaded lounging areas framed by lush, professionally lighted landscaping. Behind a private gate, a six-car garage with car lifts and a grand motor court deliver rare parking and storage for a beachfront property of this caliber.
Most remarkable of all is the opportunity that comes with the land. The estate is offered as a double lot, conveying two parcels together, which provides something almost unheard of on 30A, namely room to build. As illustrated in the accompanying renderings, the additional parcel can become the heart of a true private compound, with space for a regulation pickleball court, an expanded resort-style pool, and even a second residence of approximately 8,000 square feet. Whether the vision is a multi-generational family retreat, an entertainer's paradise, or an income-generating estate, the canvas is yours to complete.
Gated, elevator-served, and approved for short-term rental, this is both a turn-key income producer and a generational beachfront legacy. Ultimately, the chance to own this much of the Gulf, with the freedom and space to make it your own, simply does not come along on 30A.
