451 Washington Street

Designed by prominent New York City architect Stephen Decatur Hatch, the six-story building at 451 Washington Street was constructed as a warehouse in 1891 and converted to co-ops in the 1970s. Citing its striking combination of neo-Flemish and Romanesque Revival architectural styles, the city's Landmarks Preservation Commission designated the Fleming Smith Warehouse as a landmark in 1978. One of the 19th-century building's six co-op apartments hit the market recently, asking $3,495,000 for a three-bedroom corner loft.
