About this home
Single Family · Built 1927 · Historic
Welcome to 206 Knollwood Avenue, a charming Tudor home tucked away on a quiet cul-de-sac in Mamaroneck’s highly sought-after Harbor Heights neighborhood, offered for the first time in 35 years.

The sun-filled kitchen flows seamlessly into a cozy breakfast area and a formal dining room with French doors that open to an outdoor deck, perfect for effortless indoor-outdoor entertaining. The main level also includes a warm and inviting den, along with a versatile bedroom or home office situated across from a full bath adorned with the home’s original tilework. Upstairs, the spacious primary suite offers a beautifully appointed ensuite bath, complemented by two additional bedrooms and a shared full hall bath. The finished lower level provides flexible living space with a recreation room, laundry area, generous storage, and direct access to the driveway and backyard. Ideally located just moments from Mamaroneck’s vibrant village amenities, including dining, boutique shopping, schools, library, Emelin Theater, Harbor Island Park and beach, and Metro-North for a convenient commute to NYC. This is a rare opportunity to own a lovingly maintained home in a premier community.
