A rarely available, extra-wide townhome that combines elbowroom elegance and fine detail with a wealth of layout options. Upgraded and thoughtfully renovated, the 6,500 sq. ft. home is currently configured as a double duplex with an 1,800 sq. ft. medical office on the ground floor, providing the potential for substantial monthly income flow. 166 Clinton Street can easily be re-converted to its original, gracious, single-family layout or quadraplex with professional or residential garden rental. There is plenty to appreciate in this airy, 25+ foot wide home right now. The owner's duplex occupies the building's "best cut." Its living room, formal dining room, eat-in kitchen, powder room, laundry room and large west-facing deck occupy the parlor level. An elegant internal staircase leads to the third floor, where there are two master bedroom suites plus a possible third bedroom now used as a study. The top two floors are currently configured as a separate rental unit, with three bedrooms plus a family room, a west-facing deck and tons of storage. Surrounded by other landmark townhouses, 166 Clinton Street is close to the Heights' best shopping, dining and amenities. Nine subway lines are a few blocks away including the Jay Street-Borough Hall mega-transportation hub. Built in the late 1800s and well maintained, 166 Clinton Street is a home for today with the irreplaceable graciousness of the neighborhood's historic past.
