Under Construction. You're in for something special with this new beachfront construction set to be completed by December, 2025. Located on over a quarter acre on Longboat Key, this contemporary luxury home is directly on the beach with stunning Gulf views. Designed with a modern coastal aesthetic, it’s built for both style and comfort. Inside no detail is overlooked. From sleek Walker Zanger porcelain tile to custom cabinetry and polished nickel fixtures, the finishes are top-tier. The gourmet kitchen features an expansive layout with a large waterfall-edge island, double Wolf ovens, Sub-Zero refrigeration, a full-size wine cooler, and a Wolf induction cooktop—everything you need for serious cooking or entertaining. Primary suite is a true showstopper with floor-to-ceiling glass sliders that open wide to a sweeping terrace. Gulf breezes flow through the space, and the shimmering azure water is always in view. Inside, the suite offers a spacious walk-in closet and a spa-like bath featuring tiled walls, a walk-in shower with multiple heads, a soaking tub, dual floating vanities, and a private water closet. Upstairs, an executive office and three generous bedroom suites—each with its own walk-in closet—gives plenty of space for family or guests. A fourth bedroom shares a cozy den, perfect for lounging or movie nights. The grand-level outdoor space takes full advantage of its beachfront setting with a 36-foot lap pool, sun shelf, heated spa, and a fully equipped summer kitchen with a grilling station—ideal for effortless entertaining, all just steps from the sand.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
