Introducing one of the North Fork's most iconic properties, seamlessly blending historical grandeur with contemporary living. Originally constructed circa 1915, this Georgian estate served as additional living quarters for the family of the former 40-acre waterfront Cosden estate. Today, this exceptional residence offers over 6000 square feet of luxurious living space featuring six bedrooms, all ensuite and is situated on a serene acre of land positioned across from a scenic preserve. An entertainer's dream, the house welcomes guests with a magical courtyard entrance, setting the stage for epic gatherings with family and friends. Inside, soaring ceilings and abundant windows infuse the home with natural light, creating a bright and inviting atmosphere. A large great room features trayed ceilings, herringbone floors and a huge wood-burning fireplace, adding warmth and character to the space. The recently renovated chef's kitchen is anchored by an oversized center-island with an enormous custom skylight above. A formal dining room with vaulted ceilings awaits holidays and dinner parties. A large playroom serves as a flex media room. The south-wing of the residence features the original stables with a secluded and private office just beyond. Additionally, a large temperature-controlled wine cellar in the basement caters to connoisseurs and collectors alike. Step outside to the park-like backyard, where a heated gunite pool awaits amidst mature specimen trees and ornamental plantings, offering a private retreat. An outdoor shower is designed to take in the beautiful gardens. A timeless East End investment in the heart of the North Fork., Additional information: Appearance:MINT,Interior Features:Guest Quarters,Separate Hotwater Heater:Y
