BUILT TO LAST. 519 Rountree is new construction built entirely of concrete block (CBS) across every level-unlike many barrier island homes that transition to wood-frame construction above the flood elevation. The residence has already experienced recent hurricanes without damage. NEW CONSTRUCTION. 519 ROUNTREE is a privately positioned coastal residence offering over 6,400 square feet of indoor and outdoor living, including approximately 5,200 square feet under roof and a 1,100 square foot elevator-accessible rooftop terrace, located within Longboat Key Estates. GULF LIVING EXPERIENCE. At 519 Rountree, days begin with morning air carrying the salt-kissed character of the Gulf and conclude with glowing sunsets that define the Florida coastline. This is not simply proximity to the beach - it is immersion in it. Positioned just moments from the sand, the home offers balcony and rooftop experiences designed for sunset entertaining, open-air dining, and the effortless rhythm of Gulf living from morning through evening. WATERFRONT LIVING. A waterside deck is currently in process, transforming the canal setting into a true extension of the home's outdoor living experience, subject to permitting. Flexibility remains for a variety of dock and lift configurations, tailored to buyer preference. DESIGN AND EXECUTION. The newly constructed residence has withstood three recent hurricanes without damage, a testament to its quality, elevation, and thoughtful execution. Each level is purposeful in both design and function, delivering a vertical lifestyle that feels intuitive, private, and refined. FURNISHINGS. For buyers seeking the residence exactly as photographed, the complete furnishings and curated design package may be acquired separately. FINAL NOTE. 519 Rountree delivers the atmosphere buyers seek when they say they want Gulf living - quietly, privately, and without excess.
