483 Middle Line Hwy Set atop an extraordinarily rare 6± acre estate, this Sag Harbor retreat commands one of the highest and most breathtaking vantage points on the East End-an offering seldom found and nearly impossible to replicate today. From this remarkable elevation, sweeping panoramic water views stretch endlessly across the horizon all the way to Connecticut, delivering dramatic sunrises, glowing sunsets, and an ever-changing backdrop of sky and sea. Large parcels of this scale have become increasingly scarce in Sag Harbor, making the combination of acreage, elevation, privacy, and view extraordinarily uncommon. Tucked behind a long private drive and surrounded by lush natural beauty, the property unfolds with a sense of arrival that feels both secluded and cinematic. Designed to embrace its stunning surroundings, the home features expansive interiors filled with natural light, floor-to-ceiling windows, vaulted ceilings, and exposed beams that create an airy, loft-like atmosphere. The open gourmet kitchen flows seamlessly into the main living spaces and out to a spectacular private yard with a Gunite pool and endless possibilities for outdoor living. The residence offers four bedrooms and three baths, including two guest bedrooms on the main level and a tranquil upper-level primary suite with soaking tub and mesmerizing elevated views. A dramatic double-height studio or entertaining space with soaring 25-foot ceilings is wrapped in treetop and forest vistas-ideal for an artist, collector, creative retreat, or unforgettable entertaining. Owned by a renowned East End art and antiques dealer, the home carries a distinctive sophistication and artistic sensibility throughout. With substantial room for expansion to over 10, 000 square feet, plus space for tennis and additional amenities, the potential here is enormous. Opportunities to acquire a property of this size, elevation, and view caliber in Sag Harbor are exceptionally rare-making this a truly legacy offering with limitless upside.
