Description

This very glamorous duplex residence is defined by its glorious and cinematic views of the Hudson River, the High Line, and the New York skyline. Comprising the top two floors of HL23, this exceptional condominium residence offers an abundance of space and style and with wide, gorgeous terraces, it invites true indoor-outdoor living. The apartment is flooded with natural light during the day and with outlooks to the shimmering city lights at night. This is penthouse living at its very finest and is truly divine. Upon entry, the elevator opens directly into a spectacular 40-foot Great Room with distinct areas for seating and dining, and a chicly modern kitchen with a host of state-of-the-art appliances by Wolf, Miele, and Subzero. With three exposures,10-foot ceilings, and floor-to-ceiling glass walls, the Great Room is surrounded by gorgeous planted terraces with ample space for dining and lounging, as well as an outdoor shower and an irrigation system. An urban oasis, the terrace is always welcoming and beckons from just beyond the interior of this glamorous entertaining space. Sunshine and glorious views are ever-present as well. A Powder Room and an ample pantry complete this floor. The downstairs private quarters benefit from the same magnificent views. With a ceiling height of over 11 feet and a lofty sensibility, this space is ample and elegant. The Primary Bedroom is striking, with a full wall of windows with views towards Midtown’s iconic skyscrapers. It is complemented by a spa-like marble Bathroom. There are three Bedrooms, each with an ensuite Bath. Completing this floor is the delightful addition of a Den and Media Room, open to one another and with south-facing views and sunlight, as well as a wood-burning fireplace. Nearby is a convenient Powder Room, as well as laundry. 515 West 23rd Street, or HL23, is a visually stunning, reverse taping tower cantilevered over the celebrated High Line elevated gardens and walkways. Designed by award-winning California architect Neil Denari, the north and south facades of the building consist of some of the largest single-pane windows ever used in residential high-rise construction, which is juxtaposed by stainless steel sculpturally-formed panels along the eastern façade. Residents in this 2008 boutique condominium benefit from the utmost in discretion, privacy, and service. The location is ideal, close to Hudson River Park, the city’s best galleries and boutiques, the Whitney Museum, and ample dining. The building has 24-hour doorman, a private fitness center, and the apartment transfers with a sizable private storage unit. Pets are welcome.
