Lovingly renovated historic estate offering state-of-the-art features while preserving its original charm and character. Once known as Half Moon Farm and home to the area's largest agriculturalist, Mr. Barrett, the property has been thoughtfully restored and modernized by the owners, internationally acclaimed photographer Alexi Lubomirski and his wife, Giada. Set amongst 100-year-old maple trees, it retains a timeless, historic feel while providing all the modern comforts desired in a weekend getaway or full-time retreat. Entering the home, the inviting foyer leads to a spacious living room complete with a library nook, window seat, and wood-burning fireplace. The newly renovated kitchen features custom cabinets with antique accents, a gas stove, butcher block counters, and a custom stone backsplash with adjacent pantry. The kitchen and living room open seamlessly to an herb and rose patio garden, dining area, and reading corner. Upstairs are three light-filled bedrooms with new carpet and ample closets. The walk-out lower level, not included in the square footage, has been fully finished with heated floors and a full bath with clawfoot tub. Outdoors, enjoy a majestic heated gunite saltwater pool with outdoor shower and a one-of-a-kind stone diving board quarried on site. Recent upgrades include new roofs and gutters (2014), updated HVAC, new water heater, and a whole-house generator. The property also includes several outbuildings: a large storage shed, wood shed, and garden shed. Ideally located less than five minutes from the private Sedgewood Club (membership required), offering lake access, tennis, and golf - 15 minutes from the train and just an hour from NYC.
