Dine in a gold-domed cupola in this $13.5M Chelsea penthouse

In the landmarked O’Neill Building at 655 6th Avenue, this duplex penthouse condo is a 21st-century luxury home that pays homage to the Gilded Age. The building dates to 1887, when it was built as a Ladies’ Mile department store. Asking $13,495,000, the penthouse is a 4,819-square-foot residence that was, until 2008, home to “Law & Order: SVU” star Mariska Hargitay. Anchoring the home’s 2,500 square feet of outdoor space is a paved terrace with a view of the gold Neo-Grec-style cupola.

On the lower floor of the penthouse, a vast 53-foot-long great room is wrapped by 220 linear feet of windows with Manhattan skyline views.

An open kitchen is anchored by a dining island, surrounded by Viking and Sub-Zero appliances and custom wood cabinetry. The kitchen is served by a butler’s pantry and a separate breakfast room.

The most memorable part of this unique living and entertaining space is the home’s historic gold-coated Neo-Grec cupola. Beneath a 43-foot high belfry, the 360-degree room can serve as a dining nook, home office, or one-of-a-kind media lounge.

The three-bedroom home’s upper level holds the primary suite. This ultra-private sanctuary has two large dressing rooms and a large mirrored bath. The suite opens onto its own private terrace.

The duplex also has a private service entry, a dedicated next-door storage unit and a laundry room. The full-service condominium building offers residents a 24-hour doorman, a concierge, and a 4,000-square-foot roof terrace with an outdoor kitchen.
