This duplex apartment, located within a historic Upper East Side carriage house, offers a private garage and outdoor space. Built in 1884 by architect William Schickel, the Romanesque Revival carriage house was once part of a "stable row" for Upper Fifth Avenue’s elite. Later, it became the studio of famed artist Mark Rothko before being converted into its current configuration of two units. The residence is accessed through the entrance at 155 or from your private one car garage. Ascend the staircase to the lower level of the duplex where you are welcomed by a spacious living area with a working fireplace and a glass enclosed terrace that allows light in from above. Across from the open living area is a formal dining room, which is adjacent to the eat-in kitchen and has access to the enclosed terrace. In the front of this level are three bedrooms (one with a working fireplace), three bathrooms as well as a laundry room. The upper level of the duplex features an atrium at the top of the stairs with tall skylights that flood the area with light. Down the hall is the primary suite which has a bedroom lined with windows that look out to the sun-filled roof terrace and a working fireplace. There is also an office on this floor, a tea room, storage, as well as access to a landscaped roof terrace. An elevator services both floors of the residence as well as the garage. Additionally there is a mezzanine with storage and a wine cellar.
