I toured a $39.5 million triplex penthouse in an iconic NYC building that's beloved by celebs and musicians. From the futuristic lobby to the Elon Musk-inspired study, it was unlike anything I had ever seen.

Katie Warren/Business InsiderI had never seen anything quite like Zaha Hadid’s design.

Curving over the High Line park in New York City’s Chelsea neighbourhood is an 11-story residential building that looks like it belongs in the future.

The building, 520 W. 28th St., is one of the last designed by the legendary Iraqi-British architect Zaha Hadid, who was nicknamed “Queen of the Curve.” That seems particularly apt when you look at the 39-residence boutique building, the only one she designed in New York before her death in 2016.

The lavish residence has attracted celebrity residents such as Sting and Ariana Grande.

Marketing and sales for the building are handled by Related Sales and Corcoran Sunshine Marketing Group, and Charlie Attias is the listing agent.

If the 6,853-square-foot, three-story penthouse isn’t enough space for you, it can be combined with the neighbouring penthouse for a total of 11,121 interior square feet and a 3,892-square-foot terrace, according to Corcoran.

I toured the building’s penthouse and its 2,000-square-foot wraparound rooftop terrace. Here’s what it looks like.

On a recent spring afternoon, I got a tour of the building and its sprawling $US39.5 million triplex penthouse.

The doorman let me into the building only after I announced my name and the name of the person I was supposed to meet. I imagine the security is part of the draw for the building’s celebrity residents, who reportedly include the musicians Sting and Ariana Grande.

From the moment I stepped into the lobby, the space felt different from any other residential building I’d ever been in.

Hadid was nicknamed the “Queen of the Curve,” and during my tour of her building, I could certainly see why.

One of the upstairs rooms was set up as a study inspired by Elon Musk. Greg Gushee, the executive vice president of Related Companies, the building’s developer, told me he could see the Tesla CEO living in the penthouse.

To me, the penthouse’s standout feature was its massive wraparound terrace.

Like in the rest of the condo, the curves of the 2,218-square-foot terrace gave it a futuristic feel. I could imagine some seriously chic parties taking place up here.

Downstairs is the family level, which includes a master suite, three bedroom suites, and a utility room.

The building’s wellness level includes a 75-foot skylit swimming pool that wouldn’t look out of place in a luxury resort.

While screening rooms have become a somewhat predictable amenity in luxury buildings, 520 W. 28th St. has a private Imax theatre. Residents can also use the building’s automated robotic parking and storage vaults.

Hadid’s building includes a sculpture garden on the same level as the High Line for tourists and locals to enjoy. But I found the most interesting piece of art to be the building itself.
