Along the pristine shores of Florida's Emerald Coast, where architectural restraint meets sun-washed serenity, Alys Beach unveils its newest Gulf-front jewel. Rising above a 53-foot expanse of private beachfront, this newly completed residence represents one of the most ambitious design collaborations ever undertaken in the community. Conceived by A Boheme Design under the direction of Darrell Russell and brought to life by Gulfview Construction, the home is an uncompromising study in precision, proportion, and permanence.Constructed entirely of solid concrete, including a concrete roof, the residence spans more than 5,200 square feet of interior living space and an additional 1,800 square feet of outdoor environments. Its generous gulf-front width, rare even by Alys Beach standards, allows the architecture to fully embrace the horizon, bathing every level in shifting bands of light while maintaining exceptional privacy and quietude.

A secluded courtyard pool sets the tone on the ground level, offering a calm, cloistered retreat framed by Venetian plaster and stone. Guest suites, a lounge and bar, and a dedicated beach-entry laundry room turn the entire floor into a refined hospitality wing.
The main living level is a sculptural, light-filled expanse where floor-to-ceiling glass retracts to unify the indoors with a gulf-front terrace. A glass-enclosed, marble-accented wine installation anchors the space as an art object, complemented by a custom European kitchen defined by clean lines, integrated appliances, and concealed storage. Entertaining flows seamlessly from intimate to elevated, supported by a dedicated scullery tucked discreetly out of view.

The third level delivers a private world of its own. The primary suite occupies the gulf side, where dawn and dusk unfold across a refined palette of stone and plaster. A custom dressing room, guest suite, office, and a secondary bar complete the floor, all connected by hallways engineered to protect both views and privacy.

Above it all, a rooftop terrace creates an experience rarely found on the Gulf Coast, a multi-level aerie anchored by a custom mosaic pool featuring a commissioned artisan inlay. With an outdoor kitchen, bar, sun lounges, and uninterrupted 360-degree vistas, the terrace functions as a private resort suspended over the shoreline.

Whole-home automation, high-efficiency mechanical systems, and impact-rated window and door assemblies ensure that the home's technical performance matches its architectural ambition. Every detail, material, and proportion reflects a commitment to longevity, craftsmanship, and intent.

Set within Alys Beach, a community celebrated for its design integrity, walkability, wellness offerings, and carefully curated town centerthe residence is as much a lifestyle statement as it is a home. It is a rare Gulf-front sanctuary crafted for those who see architecture as art, and who understand the lasting value of a home built without compromise.
