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.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
