A Warm, Luxurious New York City Duplex with a Dramatic Catwalk

An onyx "hearth" and a French limestone banquet form the perimeter of the warm living room. The carpet is from Tai Ping.

SPAN Architecture recast this two-level space in New York City—previously a photography studio—as a loft-like residence that is rich in materials. A blackened steel staircase, executed by general contractor Richard Kaleta, leads to the private quarters on the duplex's second floor. The walkway is composed of custom etched glass, stretched across an open atrium to below.

Sliding doors partition a cozy screening room, where the resident can enjoy films and television in the comfort of custom designed furniture.

Envisioned as "an apartment within an apartment," the master suite is secluded from the rest of the home, accessible via the steel-and-glass catwalk. The owner's sanctuary features a built-in bed and credenza by City.

Wrapped in Anne Sacks tile, the master bathroom is outfitted with fixtures by Kohler.
