520 West End Avenue, also known as the John B. and Isabella Leech Residence, is a landmarked mansion on the northeast corner of West End Avenue and 85th Street, on the Upper West Side of Manhattan.
The house, built as a single-family residence, was built in 1892 as the residence of Isabella and John B. Leech. Leech was a prosperous cotton broker. The architect was Clarence F. True. At the time the Leech residence was built, West End Avenue was lined with homes belonging to prosperous families.[1]
520 West End Avenue is a Romanesque Revival building, built of blocks of rusticated limestone on the first two floors with tan-colored Roman brick above. The detailing draws on Gothic Revival and Elizabethan Revival styles.[1] Built on a corner lot, it was one of the largest homes on a street of townhouses.[2] For a time it housed the Gordon-Winston School. It is now an apartment building.[1]
The house was declared a New York City landmark in 1987.[3] [4] [5]
