The building once known as the Finger Building, the new development at 144 North 8th Street in Williamsburg, sold out last summer, and shortly before the official sell-out date, penthouse 1B closed for $1.12 million. Apparently its buyer, an LLC, saw massive profit potential in the place. It is already back on the market for a frankly ridiculous-sounding $2.1 million. Why ridiculous? The oak flooring, views, and custom bathroom fixtures certainly sound lovely, but the penthouse is a 1BR?and going by the floorplan, it's technically more of a large studio.
