The spacious terrace on this $18 million Manhattan penthouse rivals the size of the average home in America.

Measuring a whopping 2,725 square feet, the wraparound terrace at the unit atop Park Avenue Court is an outdoor oasis in the heart of the city.

For context, the average size of an American home is about 2,500 square feet.

“This is an amazing terrace with spectacular city views and views of Central Park. In these times and with urban living, people really love the opportunity to be outside,” says listing agent Cathy Taub, with Sotheby’s International Realty.

Architect Steven Harris combined three apartments to create this supersized 4,775-square-foot condo with 12-foot ceilings and huge windows throughout.

Supersized views

“The views every time of day, including sunrise and sunset, are really awesome,” Taub says. “The light is extraordinary as well, a sun-drenched apartment. We like to say a sun-flooded apartment throughout the entire day because we’ve got southwest and north exposure. Really, every room enjoys a sun bath.”

The interior space is also a huge plus.

The space “is extraordinary in Manhattan,” says Taub. “It is a six-bedroom apartment with the kind of space you’d be lucky to find in the suburbs, and here it is in Carnegie Hill, which is an ideal location on the Upper East Side of Manhattan.”

The terrace can be accessed from a number of rooms, offering indoor-outdoor living. The unique floor plan also features two distinct workspaces away from the bedrooms as well as a breezy flow between the kitchen and living space.

“You’re just sort of awestruck by the volume of space,” she says. “There’s an enormous chef’s kitchen, which adjoins a great room. There’s an integration there, and the communication between the kitchen and the great room is really special. Oftentimes, you’ll have a closed kitchen or a much smaller kitchen where someone might not be able to speak with or be with their family and friends while in the kitchen.”

The building comes with a range of amenities, including an indoor pool, indoor storage, a gym, community terraces, and a door attendant.

This unit also comes with a feature high net worth buyers always crave: privacy.

“There’s a private landing, which is another special aspect to the apartment,” says Taub. “You have an elevator open to your own private landing so you don’t have to share any hallway space or elevator landings with any neighbors. It’s quite luxurious.”

Camera-ready location

The space has been a filming location for several movies and TV shows, including “The Other Woman” with Natalie Portman and Lisa Kudrow, “Law and Order: SVU,” and “Damages.”

“A location scout has been familiar with the property,” says Taub. “The space is really unique and gorgeous”

The building is located near schools, shops, restaurants, and transportation.

“There are a lot of different demographics that would love living in this apartment. We have interest from families because it’s a very large apartment with six bedrooms. Or empty nesters who want to have sort of an urban compound for their children and grandchildren to visit,” Taub explains. “Whoever gets to live here is someone very lucky.”
