Backing directly up to a protected nature preserve, this distinctive sanctuary sits along the neighborhood's beloved Christmas Lights corridor near Spanish River Boulevard, known across the community for its festive charm and welcoming spirit, all just minutes from the Atlantic sand and surf. The exterior presence makes an immediate impression with an extra-long, exceptionally wide driveway capable of comfortably parking up to ten vehicles, making it an ideal setup for car collectors, boat storage, or effortless guest hosting. Built with an unmistakable reverence for volume and light, the interior unfolds beneath dramatic soaring ceilings anchored by stunning, extra-large format tile floors. The primary gathering space centers on an entertainer's living room complete with a cozy fireplace and a dedicated wet bar, flowing seamlessly toward a well-appointed kitchen outfitted with rich stone countertops, two separate sinks for effortless prep, and a premium gas range. The first floor also hosts two reimagined, flexible bedrooms and a full bath, providing an ideal layout for guests, a private study, or a media lounge. Upstairs, the home continues to impress with two private ensuite retreats. Each upper-level bedroom features its own en-suite bathroom and opens out to its own dedicated outdoor porch, providing elevated tree-canopy views, gentle ocean breezes, and a peaceful morning coffee perch. The crown jewel of the residence is the sprawling screened porch that spans the entire width of the home, framing uninterrupted vistas of the lush, native preserve without a rear neighbor in sight. Complete with a fully equipped outdoor kitchen, this expansive alfresco loggia allows for year-round dining, entertaining, and birdwatching in complete comfort. Combining architectural character, vast grounds, and an unbeatable East Boca address, this home is an extraordinary find ready for its next chapter. Some photos have been enhanced.
