Description

The Admaston, located at 251 West 89th Street, is a classic pre-war condominium designed by architects George and Edward Blum. The building is characterized by its tapestry brick and terra cotta exterior, while the lobby retains original details including stained glass, iron ornament, and twin Carrara marble staircases. Unit 11D is an expansive three-bedroom, 2.5-bathroom residence that balances pre-war proportions with the comforts of modern city living. High ceilings and a thoughtful layout create a rare sense of openness from the moment you cross the threshold. The living and dining areas serve as a sophisticated backdrop for both quiet evenings and lively gatherings, bathed in natural light that highlights the rich hardwood floors and elegant original moldings. For casual mornings, the spacious eat-in kitchen provides a functional and inviting heart to the home, complemented by the everyday convenience of an oversized washer-dryer. The primary suite offers a serene retreat with generous closet space and a classic ensuite bathroom that echoes the building’s timeless aesthetic. Two additional bedrooms are equally well-proportioned, providing versatility for a variety of needs, alongside a secondary full bathroom and a convenient powder room for guests. Beyond the apartment, The Admaston offers a beautifully landscaped roof deck with sweeping views, as well as storage and a bike room. The building is impeccably maintained by a full-time doorman and a dedicated live-in Resident Manager. Positioned in the heart of the Upper West Side, this home puts you moments from the lush greenery of Riverside and Central Parks, the express 1/2/3 trains, and the neighborhood's premier cultural and dining institutions.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
