Single Family Home for sale in Sea Cliff, NY

for $3,199,000 with 5 bedrooms and 4 full baths, 1 half bath. This 5,180 square foot home was built in 1908 on a lot size of 0.45.

Welcome to 227 Prospect Avenue in Sea Cliff—a meticulously rebuilt residence that blends thoughtful design with exceptional craftsmanship. This inviting home, spanning 5,180 square feet, marries modern efficiency with all-new systems: HVAC, electrical, plumbing, certified septic system, dry wells, and a full generator. Rich oak hardwood floors, laid in custom herringbone patterns, set an elegant tone throughout. Ten-foot ceilings on both the first and second floors—plus the finished basement—create an airy, expansive feel. The open-concept layout flows effortlessly into spacious living and dining areas—ideal for quiet evenings or hosting guests. The timeless chef’s kitchen is a standout: Wolf appliances, a Sub-Zero refrigerator, a generous island, and 2.5-inch quartz countertops. Four working fireplaces and built-in speakers bring warmth and subtle sophistication to the main level. A dedicated first-floor mudroom adds everyday practicality, keeping boots and coats out of sight. Upstairs, the primary suite feels like a private retreat—complete with a balcony, oversized walk-in closet, and spa-like bath featuring a soaking tub, oversized shower, and dual vanities. With five bedrooms total (three ensuite), the home also offers a first-floor guest suite with its own private entrance. Downstairs, a finished basement delivers versatile space—two decorative fireplaces, a second laundry room, and even dual mudrooms—for ultimate convenience. Outside, a brand-new oversized bluestone patio, outdoor kitchen, and wraparound mahogany porch are framed by lush, private landscaping. A one-and-a-half-car detached garage rounds out the convenience. All of it, including beach access, just a quick, easy commute to NYC.
