This is a quirky New York apartment if we’ve ever seen one. It occupies a former Chelsea parking garage at 239 West 18th Street that was later used as a warehouse to store vinyl records. At some point down the line it was converted to a four-unit condo. And this particular unit encompasses much of the building: a third floor loft, a commercial space on the ground floor, storage in the basement and garage, exclusive use of building’s roof, 7,500 square feet of air rights, and indoor parking. (All that space covers 6,143 square feet total.) The architect-designed interior retains the grittiness of the parking garage, awash in concrete finishes from the floor to the bathtub. The whole shebang is asking $11 million.
