Description

Located in one of Carnegie Hill's most coveted Fifth Avenue cooperatives, 1107 Fifth Avenue, once home to Marjorie Merriweather Post, is a unique and majestic five-bedroom residence offering grand proportions, timeless elegance, and breathtaking views of Central Park and the Reservoir. A private elevator vestibule opens to an impressive 24-foot gallery, from which the apartment's principal rooms unfold. The magnificent 36' x 29' double living room features a wood-burning fireplace and four oversized windows framing sweeping views across Central Park. To the north, a gracious formal dining room is distinguished by beautiful hand-painted murals. The corner primary suite enjoys spectacular park views, as well as views of the Museum's striking Châteauesque facade. A generous primary bath connects to a dedicated dressing room, complemented by extensive custom built-ins. Four additional well-proportioned bedrooms offer charming views of the Museum and the historic townhouses along 92nd Street. At the rear of the gallery, a spacious eat-in chef's kitchen features custom cabinetry, abundant storage, and a separate dining area comfortably accommodating six to eight guests. Adjacent to the kitchen, a sun-filled library/media room enjoys beautiful morning light. A separate laundry room and full staff bath complete the thoughtful layout. Built in 1925, 1107 Fifth Avenue offers an exceptional standard of full-service living. Residents enjoy a rooftop terrace overlooking Central Park and the Reservoir, a fitness center, 24-hour doorman, elevator operator, and private storage. The building is also pet-friendly.

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
