Description

Turnkey High Floor Park Avenue Perfection

Designed in 1927 by renowned architect Mott B. Schmidt, 1088 Park Avenue is among Carnegie Hill's most coveted full-service cooperatives. Perched on the entire 12th floor, Apartment 12A is a renovated eight-room residence (originally nine rooms) that offers rare full-floor privacy as well as exceptional light. This move-in-ready home combines classic architecture with contemporary finishes.

A private elevator landing opens to an elegant gallery foyer, setting the tone for the large and gracious proportions found throughout this apartment. Oversized windows on ALL four exposures - north, south, east, and west - fill the residence with natural light from sunrise to sunset. Additionally, there are tranquil views over the building's recently renovated and landscaped historic private garden.

The corner living room is centered around a wood-burning fireplace and framed by high ceilings and handsome herringbone floors. The adjacent formal dining room is ideal for both entertaining and everyday living. It is seamlessly connected to the heart of the home: a stunning custom eat-in kitchen.

Recently renovated, the kitchen features richly veined Calacatta marble countertops and backsplash, bespoke cabinetry, a substantial center island, banquette seating, and premium appliances. Equal parts showpiece and workspace, it is as functional as it is beautiful. A butler's pantry and in-unit washer/dryer add further convenience.

The private bedroom wing offers serenity and separation from the entertaining rooms. The primary suite is bright and peaceful, with excellent closet space including walk-ins and a beautifully appointed bath. Additional bedrooms are generously scaled and versatile, while a separate library/guest room and proper staff bedroom with bath provide rare flexibility for modern living, guests, office use, or service.

Throughout the home, original prewar character has been thoughtfully preserved and elevated by bespoke millwork, designer lighting, custom built-ins, and a sophisticated decorative sensibility.

Residents enjoy white-glove service from an exceptional long-tenured staff, 24-hour doormen, a live-in resident manager, two private fitness centers, bicycle storage, private storage, and Park Avenue's loveliest landscaped interior gardens. Ideally positioned moments from Central Park and Museum Mile, the building offers immediate access to the finest shopping, dining, and cultural institutions on the Upper East Side.
