Situated on a serene, waterfront street with enchanting views of Upper Sag Harbor Cove, this meticulously renovated and expanded residence is one of only four homes on Green Street, offering a rare sense of peace and unparalleled privacy in the heart of Sag Harbor Village. Upon arrival, the home's curated landscape and perfectly proportioned architecture captivate the eye. Gas lanterns cast a warm glow on the welcoming Dutch door, hinting at the refined interior envisioned by acclaimed designer and Stanford White Award winner Bryan Graybill. The expanded main floor flows effortlessly, anchored by a spacious living room with a gas fireplace and views of the Cove, and a dining room that is perfectly proportioned for both large gatherings and intimate dinners. Bathed in natural light, the sunroom extends the full length of the home, and includes a wood-burning fireplace and floor-to-ceiling UV-glazed windows that frame the lush, private garden and heated pool. The newly added chef's kitchen is a masterpiece of form and function, centered around a Lacanche range and a classic farmhouse sink. Custom cabinetry with discreet, integrated storage solutions and hidden controls for lighting/HVAC create a seamless aesthetic. The main level is completed by a newly added side-entrance mudroom and a beautifully appointed powder room. The upper level hosts three private bedrooms and three luxurious full bathrooms. Two of the bedrooms serve as potential primary suites, each offering vaulted ceilings, separate sitting areas, and distinct views - one of the tranquil Cove, the other of the verdant garden. The bathrooms are a study in timeless luxury, finished with exquisite marble and fixtures that elevate the spaces both visually and tactilely. A washer and dryer are also located on this level for added convenience. Descending the exposed-brick staircase, the new lower level reveals a climate-controlled wine cellar, a second laundry room, and a cedar-lined pantry. Throughout the residence, no detail has been overlooked, from the antique glass panes in the windows to the brass rotary light switches, each element chosen contributes to the home's unique character and enduring quality. Outside, the south-facing back garden is a private oasis. A manicured lawn, a heated gunite pool, and a rough-cut basalt stone patio create an idyllic setting for outdoor living. Subtle landscape lighting illuminates the space at night. This stunning turn-key property presents a flawless combination of dedicated design consistency with the practical convenience of a perfectly thought-out home. The location is unparalleled given its proximity to the shops and restaurants on Main Street, its direct water access to Upper Sag Harbor Cove, and its quiet setting on a cul-de-sac street.
