Argentinian-born designer Carlos Otero, whose work has appeared in Architectural Digest, Elle Decor and other shelter magazines, is listing his Chelsea duplex at 444 W. 23rd St. for $3.1 million.
The gut-renovated two-bedroom, two-bathroom co-op is in a six-story, 1857 building known as part of the Fitzroy Townhouses.
It is currently configured as a one-bedroom with a home office or lounge.
The main floor features a living and dining room, galley chef’s kitchen, 13-foot ceilings, two woodburning fireplaces and double-height windows.
There’s also floor-to-ceiling custom cabinetry, built-in desks, a walk-in closet and marble bathroom.
The second floor also boasts French doors that lead to a terrace overlooking landscaped gardens.
The main bedroom — with soundproof windows, blackout shades and lots of storage — is on the lower level.
The listing brokers are Jerrie Butler and Alex Guidera of Corcoran.
