Artist James Turrell’s former home and studio at 26 Gramercy Park South has hit the market for $1.95 million.

That’s less than the $2.1 million the current owners paid for it in 2014, when Turrell sold it to them.

Turrell is known for his work with light as well as a large-scale artwork within the extinct Arizona volcano, Roden Crater, which he’s devoted some 40 years to making.

There, Turrell created winding paths and a 44-foot-wide concrete ring surrounding the volcanic hole that, from the sky, looks like a “giant, unblinking eye,” according to one description. Turrell is also known for his popular 2013 Guggenheim exhibit, which reimagined the building’s rotunda with various colors.

Turrell’s old one-bedroom, two-bathroom apartment is a combination of two separate units. (There is space for a second bedroom.)

It features Gramercy Park views through four living room windows and comes with a coveted key to the park. The current owners say that Turrell was a “perfectionist” who obsessively worked with architect Annie Kwon to make sure that the apartment’s light was maximized.

He sent back the floor of the shower four times until it could be installed in one piece without a crack.

Corcoran’s Paul Kolbusz, Melissa Sargeantson and Sara Gelbard have the listing.
