Introducing Stony Hill Farm, a timeless farmhouse estate inspired by the natural beauty of the East End. Nestled within one of Amagansett's most compelling settings, where protected farmland, equestrian trails, and world-renowned ocean beaches come together in harmony on 5.06 acres+/- overlooking an additional 3.22 acres+/- of agricultural reserve. This estate offers an unparalleled sense of privacy and serenity just moments from Atlantic Avenue Beach, Indian Wells Beach, and the boutiques and restaurants of Amagansett Village. Rooted in the historic Stony Hill Farm landscape, these grounds remain deeply connected to Amagansett's agricultural and equestrian heritage, where rolling fields, protected reserve, and open skies continue to shape the character of the land. A long, gated tree-lined drive, complemented by a separate gated service entrance, leads to the approximately 8,556 SF+/- cedar-shingle farmhouse, positioned atop a private rise overlooking the reserve. Expansive covered porches, sun-filled interiors, and sweeping views establish a seamless relationship between the home and its bucolic setting. The entry foyer opens to a carefully composed floor plan, where each room unfolds with a balance of refined finishes and modern comforts. At the heart of the home, the chef's kitchen connects effortlessly to a welcoming living room with multiple sets of French doors opening to a screened porch. Beyond, an elegant formal living room features a cozy reading nook overlooking the reserve, a sunroom, and a wall of French doors that open to the outdoor dining patio, creating an ideal setting for year-round entertaining. Additional first-level spaces include a private study, sitting room, and mudroom. The second level offers four bedrooms, including a primary suite with a fireplace, sitting area, dual spa-inspired bathrooms, and separate walk-in closets. Each guest suite is thoughtfully designed with its own architectural character and tranquil views across the surrounding landscape. The finished lower level features a media room, wet bar, bedroom with walkout access, full bathroom, and additional flexible living space. Outdoor living is equally exceptional. A western-facing 20'x50' heated gunite pool and spa are complemented by a custom 625 SF+/- pool pavilion anchored by a fieldstone fireplace. Expansive lawns, a fenced vegetable garden, a detached two-car garage, and covered porches and terraces overlooking protected reserve create an idyllic setting for both quiet retreat and large-scale entertaining. Adjacent to Balsam Farm and the Amagansett trail system, the property offers access to miles of scenic riding and walking trails, placing nature and recreation just beyond your doorstep. Rich in history, surrounded by protected landscapes, and just minutes from some of the Hamptons' most celebrated ocean beaches, Stony Hill Farm presents a rare opportunity to own an estate where Amagansett's agricultural roots meet the relaxed elegance of coastal living.
