Description of Property
One or more photo(s) has been virtually staged. Under Construction. 519 ROUNTREE ON LONGBOAT KEY. Designed as a private coastal retreat, 519 Rountree is a rare architectural statement positioned on a unique triangular lot with dual water exposure, offering both Gulf and canal views. Very few homes in Southwest Florida provide this level of orientation, privacy, and vertical lifestyle design. Built with a gallery-inspired editorial aesthetic, the residence unfolds vertically with a distinct experience on every level, similar to a private boutique hotel or resort-style home. ARCHITECTURE AND DESIGN: Vertical lifestyle-driven layout emphasizing privacy and flow, neutral gallery palette with sculptural finishes, professionally curated interiors, and abundant natural light with Gulf and canal views throughout. LIFESTYLE LAYOUT: FIRST LEVEL features a resort-style pool and jacuzzi with full sun exposure, gazebo overlooking the canal with boat access, garage and a new 34' seawall (with a planned dock). SECOND LEVEL (GUEST AREA) offers guest bedrooms and bathrooms, lounge with bar, laundry, and separation from the main living level for hotel-style privacy. THIRD LEVEL (MAIN LIVING) includes living and dining areas with Gulf views, chef’s kitchen, owners suite with spa-style bathroom and steam shower, balcony, and an additional outdoor BBQ terrace. FOURTH LEVEL (ROOFTOP TERRACE) delivers 360° Gulf and canal views with outdoor kitchen and BBQ, designed for sunset entertaining and elevated coastal living. WHY IT STANDS OUT: Rare dual water views, a private rooftop terrace ideal for entertaining or intimate sunset dining, a vertical layout that enhances privacy and flow, editorial gallery-style interior curation, and versatility as either a primary residence or a luxury coastal retreat. DETAILS THROUGHOUT: Smart home with designated server closet, full-home LP gas generator, private office, second laundry room, integrated home audio, and more. For buyers seeking the home exactly as photographed, the complete furnishings and curated design package will be made available for an additional cost. 519 ROUNTREE IS NOT SIMPLY A HOME; IT IS A CURATED LIFESTYLE EXPERIENCE.
