“When we bought it, the apartment felt rather uninspired and confined, but it had such great potential,” resident Bart says. The building, on Sixth Avenue, is part of the Ladies' Mile Historic District, which once housed the city’s most famous department stores. The building was commissioned by Irish merchant Hugh O’Neill to house his dry-goods emporium. It now houses a mix of commerce and condos.  Photo 1 of 7 in Luminous Apartment in a Historic NYC Building
