Description
Virtually Staged. Under Construction. Under Construction. Pre-Construction | Custom Build | Water to Front & Rear A once-in-a-generation opportunity on one of
Longboat Key's most extraordinary streets. Lyons Lane is a truly singular address — a quiet, private enclave in North Longboat Key where homes enjoy an exceptionally rare double-water setting, with sparkling canal frontage to the rear and serene, protected wetland and mangrove views to the front. This is island living at its most private and unspoiled. Design Your Dream Home The vision is still yours to shape. The buyer has the rare opportunity to work directly with the architect to customize the layout, finishes, and features of this brand-new custom home before it's complete. From floor plan adjustments to material selections, this is your chance to create a residence that is uniquely and entirely your own without the years of planning that a true ground-up build typically demands. The property sits on a prime lot with water on both sides; the property includes an existing pool ready to be incorporated into your design, along with a private boat dock and lift with direct access to Millar and Sarasota Bays and no fixed bridges to the Gulf of Mexico. For the boating enthusiast, it simply does not get better than this deep water access, protected dockage, and open water within minutes. Lyons Lane — Longboat's Best-Kept Secret Unlike any other street on the island, Lyons Lane offers homes on one side only, with lush native mangroves lining the opposite side — ensuring that your views, privacy, and natural surroundings will never be compromised. It is one of the few locations on Longboat Key where you can wake up to undisturbed natural beauty in every direction while remaining just moments from the finest dining, boutique shopping, and white-sand Gulf beaches the island has to offer. Longboat Key — Florida's Premier Barrier Island. Stretching 11 miles along Florida's Gulf Coast with over 25 miles of combined waterfront between the Gulf of Mexico and Sarasota Bay, Longboat Key is consistently ranked among the most desirable addresses in the country. The island attracts discerning buyers who demand privacy, natural beauty, and world-class amenities — including the legendary Longboat Key Club, with 45 holes of championship golf, a full-service deep-water marina, spa, and beach club. Opportunities like this — a custom home, double waterfront, dock and lift, and the freedom to personalize are extraordinarily rare on Longboat Key. Don't miss your chance to build exactly the island life you've always envisioned
