At 1158 Fifth Avenue, one of Carnegie Hill's storied park-front cooperatives, Residence 4A offers grand prewar proportions, sweeping park views, and a layout made for both entertaining and everyday life. Set directly across from Central Park on the Upper East Side, this expansive eight-room, threebedroom residence of approximately 2,500 square feet carries the scale and stature of a true prewar home. From four major rooms, Central Park unfolds in treetops, sky, and changing seasons—a view that becomes part of the home's daily rhythm. Arrival sets the tone. A semi-private elevator landing opens to a gallery of nearly twenty feet, an introduction full of procession and quiet drama. From there the rooms unfold with the proportion and flow that define New York at its most elegant. The living room is grand yet deeply inviting, anchored by a wood-burning fireplace and framed by oversized windows that place Central Park front and center, light pouring across its generous volumes. The formal dining room continues in the same spirit, equally suited to large gatherings and intimate evenings at home. Throughout, the interiors honor the home's prewar pedigree: rich dark floors, custom millwork, and crisp, considered detailing that feels timeless rather than tied to any one moment. The renovated eat-in kitchen is warm and highly functional, with custom cabinetry, substantial pale stone, and a large center island for prep, seating, and gathering. The appliance suite is exceptional, anchored by a Sub-Zero refrigerator and Miele appliances, including built-in wall ovens and an integrated coffee system. The layout is uncommonly flexible. Beyond the three principal bedrooms and three baths, a versatile fourth room adapts easily as a den, library, guest room, or media room, while a separate office or staff room sits discreetly apart. Set away from the entertaining rooms, the private quarters have a serene, removed quality: the primary suite is spacious and tranquil, the additional bedrooms well proportioned and filled with soft light, several with open or leafy outlooks. The baths are understated and timeless, with stone finishes, glass enclosures, and clean lines. What makes 4A memorable is how rarely its essential qualities coexist: Fifth Avenue scale and architectural stature alongside genuine comfort and flexibility. Central air and an in-unit washer/dryer add everyday ease, while the generous, well-proportioned rooms offer a rare foundation—a home to enjoy as it is today, with room to make it your own over time. Through it all, Central Park remains its defining luxury. Built in 1924 and designed by C. Howard Crane and Kenneth Franzheim, 1158 Fifth Avenue is among Carnegie Hill's enduring addresses, distinguished by its French Renaissance façade and dramatic octagonal, double-height lobby. This full-service prewar cooperative offers a full-time doorman and concierge, resident manager, fitness center, bike storage, and private storage. Just beyond its doors are Museum Mile, the Central Park Reservoir, Madison Avenue shopping, and the Upper East Side's most beloved cultural and culinary destinations. Financing permitted up to 40%.
