This massive 4,000SF duplex penthouse loft is bathed in light from 4 exposures and offers unobstructed views of midtown Manhattan that are guaranteed to take your breath away! Step off the key-locked elevator where a private landing leads to a spectacular 4-bedroom penthouse residence and a dramatic sky-lit studio offering the perfect separation between live and work. Enter the residence to find an expansive 40-foot wide Living/Dining room with 11-foot beamed-ceilings, a working fireplace and iconic views of the Chrysler Building and the city beyond from a wall of double glazed picture windows. Nearby, you'll find the large windowed chef's kitchen and adjacent lounge. Just beyond, a hallway leads to 3 bright bedrooms and 2 full bathrooms. Off the living room, a wide curved staircase leads up to the sun-blasted penthouse level currently used as a primary bedroom suite with access to a large, fully irrigated private roof terrace with multiple seating areas and sweeping city views. Separated from the residence is a large working studio with its own kitchen and bathroom. This wonderful space is completely independent, or can be joined with the main residence to create a magnificent six bedroom home. The options are endless! Additional amenities include multi-zoned central air-conditioning, a vented washer-dryer, tons of storage and custom lighting on dimmers throughout. Built in 1912, and converted to cooperative in 1981, the 12-story steel and concrete building features a dramatic lobby, a key-locked passenger elevator, separate freight elevator, an on-site superintendent Monday-Friday and a Butterfly virtual doorman system compatible with your smart phone, allowing you to communicate remotely with vendors, accept packages and provide access for guests. And of course there's the convenient location right off of Park Avenue, in close proximity to the neighborhood's best restaurants, shopping, Eataly, Madison Square Park and all modes of public transportation. A unique and flexible offering with the best that New York has to offer right at your doorstep. Shown by appointment only
