Ceiling heights soar throughout the entire townhouse. Designed to bring light inside by premier architects George Nemeny and Debra Reiser. The townhouse has a rooftop terrace and a full 20'x30' garden. There is central air throughout the townhouse, multiple zones, and there is a finished basement. The original 1877 stoop and staircase are intact. Currently converted to a two-family house, the owner's triplex is unique. A double-height living room with a wood-burning fireplace is anchored by a sensational wall of glass overlooking the garden. Light permeates throughout at all hours of the day, giving one a breathable and airy feel when inside. The single-car garage can be expanded to accommodate more and larger vehicles as well as EVs.
