About This Property

2024 modern farmhouse by Marsella Architects combines timeless architectural character with the quality, efficiency, and comfort of new construction with 5 bedrooms and 3.5 baths designed for today's lifestyle! Enjoy the big backyard of this rare 9,369 sq ft corner double lot.  Just a 10-minute walk to the Mamaroneck Metro-North station and the restaurants, shops, and nightlife of Mamaroneck Avenue.

The sun-filled main level was built for effortless living and entertaining, featuring an open-concept layout with a stunning eat-in kitchen complete with oversized waterfall island, quartz countertops, GE Cafe appliances, farmhouse sink, pot filler, and floor-to-ceiling pantry storage. The kitchen flows seamlessly into the dining area and expansive family room/den, while a separate living room anchored by the original wood-burning fireplace adds warmth and character. A dedicated office with closet provides flexibility for guests, work-from-home, or a potential fifth bedroom.

Upstairs, the spacious primary suite features walk-in closets and a spa-inspired bath with soaking tub, glass-enclosed shower, and double vanity. Three additional bedrooms and a full hall bath complete the second floor. The finished lower level adds ~862 sq ft of living space including a large recreation/media room, full bath, laundry room, and flexible bonus space perfect for a gym, playroom, or movie nights.

Designed with both style and performance in mind, the home features James Hardie board-and-batten siding, matte black accent roofing, Marvin Elevate casement windows, wide-plank white oak flooring, spray foam insulation throughout, and a high-efficiency multi-zone Rheem heat pump HVAC system with central air and fresh air exchange. Additional highlights include an attached garage, bluestone porch and patio, upgraded PEX plumbing, new 200-amp electric service, and professionally designed landscaping.

A rare opportunity to own a turnkey modern farmhouse offering elevated design, energy efficiency, and walkable village living.
