Peep ‘Runway’ star Christian Siriano’s NYC penthouse pop-up

His creativity knows no bounds.

“Project Runway” winner Christian Siriano, who has dressed Michelle Obama, Victoria Beckham, Jennifer Lopez — and lots of single-name icons including Oprah, Zendaya and Rihanna — has taken the art of the pop-up to new heights.

The glam fashion and interior designer is transforming an Upper East Side penthouse into an interior design pop-up to launch this January. It will be at 1289 Lexington Ave. There, Siriano Interiors will drop its latest collection of bespoke furniture pieces in the $13.75 million skypad — a star in its own right.

The penthouse, Siriano told Gimme Shelter, “is filled with so much beautiful natural light, so I wanted to keep the space light and modern, but powerful and playful at the same time. I wanted the space to feel like a gallery where each piece has a chance to shine and will surely spark a conversation.”

Siriano added that the pop-up showcases his new furniture collection pieces, as well as French and Italian antiques “from the ’40s to the ’60s.” 

The five-bedroom, 5½-bathroom home was itself designed by award-winning firms HOK and SheltonMindel.

At around 4,000 square feet, the residence boasts a custom staircase to a 1,679-square-foot private corner terrace with an outdoor kitchen. The home opens to a double-height gallery with a large skylight and a corner great room with window walls showcasing city views.

An open entertaining/dining area is divided by a marble-clad, double-sided fireplace.

There’s also an open chef’s kitchen and a den that can serve as a guest bedroom.

“We are thrilled to be collaborating with Christian. The installation promises to be a testament to his versatility as an interior designer and his ability to enliven this incredible home with his signature flair,” said Brown Harris Stevens’ Jill Bernard, who heads the building’s sales.

As the latest Zeckendorf building, 1289 Lexington joins 520 Park Ave., 18 Gramercy Park South and 15 Central Park West in the collection. Building amenities include a lounge with a billiards table and outdoor space, a roof terrace with fireside seating and a grill, a windowed gym designed by the Wright Fit, a playroom, a music room, a conference room and private tutoring/study pods. 

Founded in 2019 — the same year that the building launched — Siriano Interiors is a full-service interior design studio. Projects range from “chic Tribeca penthouses to boutique hotels around the US.” The collection is available on its website and 1stDibs.
