Property Description

Set behind a gated private driveway on 2.33 acres, this fully renovated 8,800 sq ft Colonial delivers estate-level living with total privacy in Bay Shore. Reimagined in 2023, the home pairs classic architecture with modern design, scale, and function—built for those who want space without compromise. The interior offers seven primary-sized bedrooms and four full bathrooms, creating flexibility for multi-generational living, work-from-home lifestyles, and elevated entertaining. At the center of the home is a sleek, open-concept chef’s kitchen that anchors the main living spaces and flows effortlessly into a formal dining room and expansive gathering areas. Three gas fireplaces add warmth and architectural presence throughout.
Additional highlights include central air conditioning, forced hot air heating, a three-car garage, and a dedicated game room—designed for both everyday living and hosting at scale. Tucked far off the road and surrounded by mature grounds, this private estate offers rare acreage, privacy, and volume, all within reach of Bay Shore’s conveniences. A turnkey property where size, setting, and style come together seamlessly.
