A penthouse duplex that was formerly owned by the late John Casablancas — the founder of Elite Model Management who is credited with creating the “supermodel” concept — is on the market for $4.25 million.
The 2,455 square-foot unit at 205 E. 22nd St. has two bedrooms, 2½ bathrooms and comes with a 350-square-foot landscaped terrace. The building, known as The Gramercy Habitat, was originally a 1920s brewery and has retained its original wood-beamed ceilings and exposed brick walls. Douglas Elliman’s Jared Seligman has the listing.
