Description
Extraordinary one-of-a-kind duplex Condo in the sky! No expense was spared in the meticulous renovation to customize this 3-bedroom 2,710 square foot penthouse with an additional 950 square feet of exceptional outdoor space. The keyed elevator opens directly to the lower and upper levels of this sun filled home with unobstructed panoramic views with southern, northern and eastern exposures through floor to ceiling windows. A spectacular wrap around terrace awaits just outside the living room offering unparalleled views of the Freedom Tower to the Empire State Building. Seamlessly designed by world renowned landscape architect Edmund Hollander, this terrace is truly a masterpiece to behold. This outdoor oasis boasts a six-person hot tub, private outdoor shower, gas fireplace, full outdoor sound system, a weather resistant 4K television, full outdoor kitchen and dining area with gas BBQ, and a retractable canopy. The terrace can also be enjoyed year-round by a self-irrigation system servicing the lush greenery during the warmer months and snow-melting heated floors & heat lamps for those colder months. The possibilities for outdoor entertaining all year round are endless here! This home has an equally impressive indoor living area outfitted with the highest quality finishes and stunning upgrades throughout. Returning into the living room, you will find high-end audio, lighting, and a top-of-the-line Sony 4K projector with a custom motorized screen that easily transforms this room into your own home theater. The impeccably designed chef's kitchen is a masterful work of art with custom cabinetry featuring a complete Miele appliance package along with a most perfect wine fridge that would cater to any wine enthusiast's dream. The back area of the first level features two sunny guest bedrooms, full bathroom and washer/dryer. You will also be pleased to find a new air filtration center that cleverly uses ultra violet lights to sanitize all incoming air. On the upper level lies a meticulously designed, full floor master suite boasting magnificent views of the Freedom Tower and the Empire State through floor to ceiling glass windows. The custom windowed dressing room features a custom center island, and shelving while a second walk in closet sits right across. The primary bath offers the same iconic Empire State views and is outfitted with a LaCava soaking tub, steam shower, rain showerhead, double limestone vanities, and radiant heated floors. On the opposite wing of the primary suite is a home office with a second spectacular planted and self-irrigating terrace. Virtually every room in the house has been thoughtfully designed with hidden in-wall speakers. Other special features include Venetian plastered walls, a Savant home control center, multi zoned heating and cooling, air filtration center and motorized shades. Transferred with the sale is a large double unit storage cage. 21 West 20th is a WELL and LEED certified building offering a multitude of amenities including a 24 doorman, resident lounge, outdoor garden, cold storage, bike storage and pet wash room. Conveniently located between 5th and 6th Avenue, you will enjoy some of the finest restaurants, shopping and entertainment that NYC has to offer.
