Description
Perched among the trees and meticulously renovated, Residence 3B brings the serenity of nature to the heart of the city. Bathe in golden afternoon light as it floods the living room and adjoining library, then settle in by the wood-burning fireplace and watch the Autumn sun set over Central Park "when every leaf is a flower." Designed by renowned architects Schwartz & Gross in 1925, this eight-room residence captures the timeless elegance of prewar architecture in New York. The triple-mint renovation pairs 10' ceilings and hardwood floors with period architectural details that bring warmth and distinction to the rooms. A main foyer opens to a vast central gallery, a stately prelude to the home's classicly proportioned rooms. Beyond, the generous living room is equally suited to entertaining or quiet evenings at home. The adjoining park-facing library, once configured as the primary bedroom, now serves as a second living room-an inviting retreat framed by treetops and open views. The expansive primary suite includes a luxuriously appointed marble bath and custom spacious wrap-around dressing room. The secondary en-suite bedroom is beautifully proportioned with finishes that echo the primary suite including a beautifully outfitted marble bath. The formal dining room provides a gracious setting for hosting, while the eat-in chef's kitchen with ample custom cabinetry offers a more relaxed place to gather over everyday meals. A rear staff bedroom with full windowed bath, a separate laundry closet and a powder room tucked off the entry gallery completes the layout. Nestled between 72nd and 73rd Streets, 912 Fifth Avenue is an intimate, full-service cooperative offering just 24 residences. Minutes to The Frick Collection, Madison Avenue's shops and cafes and the best of the Upper East Side. Residents enjoy a fitness center, private storage and a bike room. Pied-à-terre, trust and LLC ownership are permitted subject to board approval. Pets are permitted. Financing is not permitted. There is a 2% flip tax.

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
