OPEN HOUSE BY APPOINTMENT If you are seeking an exquisite, truly spectacular, one-of-a-kind home, imagine living in the only penthouse that juts out over the High Line. With generous outdoor space and open views, this duplex residence is perched atop HL23, the architectural sensation by Neil Denari, called sleek as an Italian sports car by the New York Times.The minute you step off the elevator, your breath is taken away by the glass-enclosed Great Room and its wrap around terrace. At the touch of a button, two retractable, floor-to-ceiling walls open and slide away, allowing the ultimate in indoor/outdoor living. Walk out from your pin-drop quiet entertaining space onto the 1,173 sqft (109 sqm) wrap terrace. Look south towards the Standard Hotel, the Whitney Museum all the way downtown to the Freedom Tower and beyond. Walk along the eastern deck and take in the juxtaposition of the classic bricks of the famed London Terrace residential complex against a postcard-like, twinkling view of the Empire State Building and Times Square. Continue north and magically reconnect with the green band of trees and grass of the northern section of the elevated park. Downstairs, the elevator opens onto the grand entry foyer, towards the light-filled living and dining space. Expansive and at the same time intimate, this dramatic room is embraced by interlocking, slanted white steel beams wrapped in floor-to-ceiling glass allowing for endless unobstructed eastern and southern views. Three well-proportioned bedrooms offer stunning light, air, and completely different views from each window. They are complimented by three full baths, and one half bath, all lined with magnificent slabs of Statuario marble. The sumptuous master suite features a wall of fully outfitted closets, as well as an over-the-top bathroom with a deep soaking tub, steam shower, heated floors, dual vanities, and an over-sized picture window. A second bedroom and third bedroom offers the same dramatic views as well as en suite baths. Add a master suite upstairs if you desire to create a generous 4 bedroom 4.5 bath home. Top-of-the-line audio visual system, motorized shades and openable windows, a multi-zoned central air conditioning and heating system are concealed throughout the apartment. Building amenities include a fitness center outfitted with TechnoGym equipment, a full-time doorman, storage, and bike room. Not to be missed.
