Listing Description

Recently upgraded, this turnkey contemporary offers the perfect suburban existence without sacrificing a vibrant, walkable lifestyle. Tucked seamlessly into one of Mamaroneck's most historic and sought-after Westchester neighborhoods, you are just minutes away from the village's best coffee shops, dining, and transit.

Inside, the home shifts into a bright, open-concept layout designed for effortless living and hosting. The main floor centers around a spectacular Great Room, where soaring cathedral ceilings and massive windows flood the space with afternoon sun. Here, the living and dining zones flow naturally into a chef's kitchen, all anchored by a striking custom stone fireplace.

Right next to the hearth, two sets of sliding glass doors open directly to a spacious rear deck overlooking the extra-large lawn-creating the ultimate indoor-outdoor flow for weekend hangs, summer BBQs, or quiet gardening. Two generously sized main-floor bedrooms and a full bath offer total versatility, making it easy to set up a dedicated work-from-home office, creative studio, or guest retreat.

The entire second level is a dedicated private sanctuary. This skylit primary suite serves as a serene escape, complete with an expansive walk-in closet and an oversized bathroom. For even more potential, the full basement features high ceilings and is already plumbed for an additional bath-a blank canvas ready to be transformed into your future media room, home gym, or lounge.

Best of all, you can skip the old-house headaches thanks to upgraded, modern infrastructure, including a high-efficiency tankless hot water baseboard heating system and a 200 Amp electrical service. Bring your personal aesthetic and move right in-the hard work is already done. Schedule your tour today.
