Set behind an electric gated entry on a beautifully landscaped 0.61-acre parcel, 9 Clearview Drive in Sag Harbor offers an exceptional blend of privacy, elevation, and waterfront living. Positioned high above Little Peconic Bay with sweeping, unobstructed bay views and breathtaking sunset vistas, the property boasts 95 feet of newly bulkheaded water frontage and direct bay access via a private staircase. The fully fenced grounds are impeccably maintained and feature mature specimen trees thoughtfully designed by Harmonia Landscape Architects, creating a serene and polished outdoor environment that feels both timeless and effortless. The outdoor living experience is nothing short of extraordinary. A heated gunite pool with an automatic cover and separate spa is complemented by a lounge area with a European pergola featuring automated louvers and retractable screens. The expansive mahogany deck includes a wood-burning fireplace, an outdoor seating and dining area, a retractable awning, and integrated outdoor speakers. A Kalamazoo outdoor kitchen with a built-in grill and refrigerator makes al fresco dining seamless. Inside, the home showcases a contemporary design with exceptional scale, clean lines, and abundant natural light across three finished levels. The double-height entry foyer leads to elegant living spaces, including a formal dining room with a wet bar and a kitchen with Wolf and Sub-Zero appliances, custom Cuiffo cabinetry, and a center island that flows seamlessly into a stunning living room with a gas fireplace and walls of glass that blur the line between indoor and outdoor living. The first floor also includes a junior primary suite with a private en-suite bath and a den/library. The second floor is comprised of three en-suite bedrooms, including the spacious primary suite with a private balcony overlooking the bay, automated blackout shades, dual walk-in closets, and a full bath appointed with a freestanding soaking tub, glass shower, and radiant heated tile. A washer/dryer and linen closet are conveniently located on the second floor, with an additional laundry room on the lower level. The lower level features an open, glass-enclosed gym, a state-of-the-art Kaleidescape home movie theater, a living room, and two guest bedrooms sharing a full bath. Designed by McDonough & Conroy Architects with interiors by Winter McDermott, additional amenities include central vacuum and a detached two-car garage with GarageTek storage, a whole-house generator, and CCTV to monitor the grounds. At approximately 6,828 sq. ft. and maintained to perfection, this home delivers a rare combination of luxury, livability, and enduring style.
