London Terrace

London Terrace is an apartment building complex in the Chelsea neighborhood of Manhattan in New York City. It occupies an entire city block on Manhattan's West Side, bounded by Ninth Avenue to the east, Tenth Avenue to the west, 23rd Street to the south, and 24th Street to the north. Construction began in late 1929 and cost more than $25 million (equivalent to $457,800,000 in 2024) on what was to be the largest apartment buildings in the world.

London Terrace has about 1,700 apartments in 14 contiguous buildings of 17 to 19 stories, and an Olympic-sized swimming pool. The complex was built by Henry Mandel Companies and the architectural firm Farrar & Watmough. The building is operated by two entities: London Terrace Towers is a co-op and managed by Douglas Elliman Property Management; London Terrace Gardens is a rental building, managed by Rose Associates.
