Don't miss this exceptional opportunity to live on a picture-perfect block in East Hampton's prime Northwest Woods. Set on three private, parklike acres in Grassy Hollow Estates, this stately Arts & Crafts style Post-Modern offers 3,000± square feet of soaring architecture, abundant natural light, and gracious living just minutes from Sammy's Beach, Cedar Point Park, East Hampton Village, and world-class ocean beaches. A dramatic double-height foyer makes a striking first impression, leading into a sun-filled great room anchored by a grand fireplace, framed by walls of glass, and lined with six farmhouse-style French doors that open to the expansive backyard and 20' x 40' heated in-ground pool. Designed with entertaining in mind, the open-concept kitchen flows seamlessly into formal living and dining areas, creating effortless indoor-outdoor living. The spacious main-level primary suite features a newly renovated marble bath with soaking tub and shower, a large walk-in closet, a private boudoir with vanity, and the second of the home's three fireplaces. Just off the great room, a charming windowed den with the third fireplace provides a cozy retreat or ideal work-from-home space. A full bath and powder room complete the main level. Upstairs, two oversized guest bedrooms offer walk-in closets and share a full bath (ensuite to one), while the bonus room above the garage can easily be converted to a legal 4th bedroom as the home was built with a 4-bedroom septic system. The 1,754± sq. ft. lower level offers untapped potential-ready to be finished; it will expand the home's total living space to nearly 4,700± sq. ft. On a lot of this size and privacy, you can expand the house up to 10,000 sq. ft. and add your own basketball and pickleball courts, an increasingly rare opportunity in today's East Hampton market. Offered as is, 2 Old Hollow Lane presents a rare chance to update or reimagine a home with excellent bones, dramatic volume, and true architectural presence-all on a prime parcel in one of East Hampton's most desirable neighborhoods. A must-see for savvy buyers, investors, and builders seeking privacy, scale, and upside potential in the heart of the Northwest Woods.
