About this home

Set on a coveted corner lot of nearly half an acre in The Brook, one of Larchmont's most sought-after neighborhoods, this expansive and beautifully updated Colonial pairs rare space and privacy with resort-style outdoor living, including a private pool and spa. Sun-drenched rooms and thoughtful updates make it as welcoming for everyday life as it is for entertaining, all just a short walk to town, schools, and the train. The first floor flows easily between the chef’s kitchen, renovated in 2021, the living room, the dining room, and a light-filled sunroom. The kitchen features a generous eat-in area and opens directly to the backyard and pool, making indoor-outdoor living effortless. Set between the kitchen and living room, the dining room is made for gatherings large and small, while the adjoining sunroom is a bright, inviting place to relax. Together, these spaces strike an ideal balance of openness, warmth, and function. The primary suite is a true retreat, with a gas fireplace, a private sunroom ideal for a home office or quiet escape, a walk-out deck, his-and-hers walk-in closets, and a spa-inspired bath with double vanities, radiant heated floors, a modern shower, and a soaking tub. Three more generously sized bedrooms, each with a window seat that doubles as storage, share two updated hall baths. On the first floor, an ensuite bedroom offers flexibility for guests, extended family, or live-in help. A window-lined year-round enclosed porch and breezeway overlooks the pool, creating a beautiful setting for dining and entertaining while connecting the main house to the garage and guest spaces. A first-floor full bath near the garage and the back door to the pool makes pool days and outdoor gatherings easy. Just a few steps up, a large recreation room above the garage, with a soaring cathedral ceiling, adapts easily as a playroom, office, gym, or guest retreat. Outside, the beautifully landscaped grounds create a private backyard oasis for summer gatherings, relaxed afternoons, and memorable evenings. Pool and outdoor improvements include a Gunite spa, new Flagstone pool deck, updated heating and filtration, lighting, outdoor speakers, and a built-in gas grill. Two new Bosch AC units with heat pumps (2026) and a Generac whole-house generator add comfort and peace of mind. Rarely does a Larchmont home combine this much space, a coveted brookside setting, a private pool and spa, inviting places to entertain, and such a convenient location. This is a wonderful opportunity to enjoy everything Larchmont living has to offer.
