Description

This newly renovated one bedroom residence on the 14th floor of 870 United Nations Plaza combines an optimized floor plan, generous proportions, and a grand sense of arrival. A welcoming vestibule with a custom display divider and coat closet introduces a home defined by substantial rooms and thoughtful separation of the living room, bedroom, and kitchen. The oversized living room offers exceptional flexibility for distinct seating and dining areas, complemented by views of the East River. The primary bedroom accommodates a seating area and a built-in desk overlooking the East River. Storage includes a fully customized, enlarged walk-in closet and an additional wall of closets. The marble bathroom features an elegant console vanity, a rain shower, and a soaking tub. Completed in 1966, 870 United Nations Plaza is a 38-story residential tower distinguished by its bronze and aluminum framed glass facade and an enduring emphasis on light, views, and architectural design. Residents enjoy doorman and concierge services, a fitness center, a roof deck, and central laundry facilities. The pet friendly building also features a private motor court and onsite parking, offering a rare level of convenience in Manhattan. Financing of up to 75 percent is permitted. Subleasing requires board approval through a formal application process, beginning with a letter from the shareholder explaining the reason for the proposed sublet.

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
