About this home

Tucked away down a private driveway off Riverside Avenue, this stylishly updated, cedar-clad home offers the perfect blend of classic charm and modern farmhouse appeal. Set on over a half an acre of level lawn, this peaceful retreat is just minutes from the train, town and coastline. The sun-filled living room, framed by twin picture windows, sets a warm and welcoming tone. At the center of the home, a beautifully renovated chef's kitchen features an oversized marble island, eat-in area, and French doors opening to a bluestone patio ideal for dining and relaxing outdoors. A butler's pantry/bar connect to the vaulted dining room, creating effortless flow for entertaining. A cozy den with a fireplace provides a quiet escape. The stone-floor mudroom leads to a rare 3-car garage with oversized barn doors for easy access. Upstairs, a spacious great room offers flexibility for a playroom, gym, family room or multiple offices. Five bedrooms and three full baths complete the second floor. With additional FAR available for future expansion, this home offers the perfect blend of immediate comfort and long-term potential in one of Riverside's premier neighborhoods.
