Upon entering the Penthouse from the private keyed elevator you are greeted by an expansive 40+ foot long living/dining room flooded with light from striking skylights and north and south-facing windows with dramatic architectural views; it showcases a working gas fireplace with a 12 foot high feature wall visible as soon as one arrives from the private elevator, 15 foot ceilings, walnut-stained wide plank solid white oak floors, and a Juliet balcony. It feels more like the great room of a Hamptons house than a New York apartment.

The brand new oversized windowed eat-in kitchen features a large center island, snow quartz counter tops, floor-to-ceiling white Bilotta cabinets, and a large walk-in pantry. Top of the line appliances include a Sub-Zero side-by-side refrigerator/freezer, a Viking Professional 6 burner stove with a hood that vents out, and both Fisher Paykel and Bosch dishwashers. Directly adjacent to the kitchen is a home office/staff room that contains a full bathroom and is an ideal home gym or sauna A stone paved powder room ideally located for guest access completes the public wing of this truly spectacular home.
The private domain of this vast home is reached by a breathtaking gallery with 12 foot high, exceptionally bright, floor to ceiling glass panes, peaked by an expanse of soaring skylights.

The great hall leads to the private wing where you first encounter an enormous media/family lounge, the much coveted and impossible to find additional gathering place for movie nights, cocktails for guests in the fully stocked bar, or a massive home office or boardroom that is truly the height of elegance and style.
To the south is the immense and opulent primary bedroom domain, sun-flooded from soaring ceilings and expansive skylights that perfectly frame stunning panoramas of spires, architecture and sky. This decadently large oversized suite is whisper quiet and features a southern-facing bank of windows with electric blinds, custom walk-in closet, second fitted closet, and a luxurious en-suite marble bathroom with a double vanity, deep soaking tub, and a separate walk-in shower. There are two additional queen sized bedrooms - both of ample proportions - with one containing an en-suite windowed bath.

Finally, off the gallery, there is a full bathroom with a Miele washer and potentially vented dryer that serves the third bedroom; both bedrooms offer generous custom closets.
This grand apartment has three zone central air conditioning and private elevator access from two key locked elevators. Pristinely painted, finished and maintained to the highest standard.
The piece-de-resistance is the private outdoor oasis. Over 700 square feet of private, landscaped, irrigated terracing - 25’ wide by 47’ long - with a three season cabana for luxurious lounging, and decked in exotic weather-proof solid hardwood that requires no maintenance and begs for grand-scale entertaining, equally inviting for intimate gatherings, with glorious views of the Met Life Tower and the Empire State Building.

It is the ideal quiet refuge - insulated from the sounds of the city - and you will feel as if you’re on vacation without ever having to leave the city.
