Located on a beautiful tree-lined block in the heart of Kips Bay, this two-family double-duplex townhome is in outstanding structural and mechanical shape and offers tremendous versatility to the discerning buyer. Currently, both duplexes are configured as 3BR/2.5ba apartments. The lower level features a glass wall formed of pivoting panoramic panels, creating a seamless transition for indoor-outdoor living--providing exceptional natural light--and a four-season view of the enormous and graciously landscaped stone terrace with planting beds hugging the perimeter. It also has exclusive access to the full-size unfinished basement. The upper level features an upgraded kitchen and offers a cohesive interior stairway directly to a (currently unfinished) roof with open views. There's lovely northern and southern light throughout, terrific storage, and a total of five usable floors. Perched on a 17 x 98.75 lot, 217 East 31st Street is a gorgeous property that boasts over 1,700 square feet of FAR/buildable SF and can easily be turned into a gargantuan stunner of a single-family if you desire. Alternatively, you can keep it as is and live in one while renting out the other, or simply rent both units out and achieve tremendous income without the burden of common charges/HOA's. Will be delivered vacant. The 6 train is three blocks away. Don't miss your shot at this one-of-a-kind opportunity! Contact us today to schedule your private showing.
