Description

This rare, captivating Park Avenue penthouse, the residence of the late Maurice Tempelsman, is defined by extraordinary landscaped terraces and an effortless, inviting flow between indoor and outdoor living. At the center of this light-filled home is a remarkably private outdoor space. Multiple flowering terraces wrap the residence, anchored by an exceptionally large main terrace that reads more like a private rooftop garden than a typical city terrace. Beautifully designed with an eye toward elegance and harmony, comfort and calm, this aerie features a variety of distinct areas for dining, lounging and entertaining, again with unparalleled privacy and peace. Views extend toward Central Park and the East River, along with a breathtaking cityscape beyond. The home offers a unique combination of natural beauty and serenity amid vibrant city living. A gracious staircase leads to the residence, opening directly into the Dining Room and setting the tone for the home, with natural light throughout. The Dining Room flows seamlessly onto the terrace, creating an ideal setting for indoor and outdoor entertaining. The generous Living Room is centered around a wood-burning fireplace. Every room enjoys access to the terrace and is bright and well proportioned. A hallway separates the private quarters. The Primary Bedroom is generously scaled and quietly situated, with excellent closet space and a windowed Bathroom. The Library, positioned just beyond, easily converts to a second Bedroom. It opens to the terrace and offers an ensuite Bath. Completing the apartment is a windowed Kitchen, separate Staff Room and Bath. Built in 1915 by Bing & Bing, 1155 Park Avenue is a highly regarded prewar cooperative designed by Robert T. Lyons, ideally situated in the heart of Carnegie Hill. Residents enjoy a full-time doorman, live-in Resident Manager, fitness center, bicycle storage, laundry facilities, and private storage. The building permits pets, allows up to 40% financing, and there is a 2.5% flip tax.
