Welcome to 203 Knollwood Avenue, a beautifully renovated Tudor-style gem nestled in the heart of Mamaroneck’s coveted Harbor Heights neighborhood, set along one of its most picturesque tree-lined streets. On a generous .25-acre lot, this home blends classic elegance with fresh, modern sophistication — all with a relaxed Hamptons-inspired vibe!
Step inside to a light-filled, chic first floor featuring a grand living room with a striking stone fireplace, front-to-back windows, and French door that opens to an expansive back deck — perfect for indoor-outdoor living. Flowing from this space is a private office with walls of windows.
A stunning new custom kitchen is the heart of the home, featuring Sky White quartzite countertops, white oak cabinetry, Cle Zellige tile backsplash, and top-of-the-line Miele appliances paired with a Samsung refrigerator. The adjacent dining room is sun-drenched and perfect for entertaining and everyday enjoyment.
The first floor also includes a convenient bedroom and a full bath adorned with floor-to-ceiling imported Spanish tile and designer finishes.
Upstairs, the luxurious primary suite boasts a spa-like bathroom with Restoration Hardware double vanity, Carrera marble shower, and a custom walk-in closet. Two additional bedrooms and another fully renovated designer bath complete this level.
The third floor offers a finished bonus space of 248 square feet with a charming barn door entry — ideal as a creative studio or guest retreat — plus a large walk-in attic for storage. The 475 square foot lower level adds even more functionality with a bonus area, full laundry room, workbench, and direct access to the 2-car garage.
This home is a rare blend of timeless character and top-tier renovation in a prime location close to parks, schools, the train, and all that Mamaroneck has to offer — all while feeling like you're living in the Hamptons, right here at home.
