London Terrace, 1929. London Terrace was a 19th century development of 80 residential buildings, stretching the full length of 23rd Street between Ninth and Tenth Avenues. The houses, designed to resemble London architecture, were built around 1845 by William Torrey, and demolished in 1929, upon the expiry of their 85-year lease. They were razed shortly thereafter, and the site was redeveloped as London Terrace Towers and London Terrace Gardens by the developer Henry Mandel. The land had been owned by Clement Clarke Moore, from whose “Chelsea” estate gave the neighborhood its name. A professor at the nearby General Theological Seminary (built on land donated by Moore), Moore is best known as the likely author of “A Visit from St. Nicholas,” first published in 1823.

London Terrance was an 1845-built housing development modeled on similar structures popular in London at the smae time. The homes were developed by Clement Clarke Moore, the author of 'The Night Before Christmas" when he divided up the land that had once been his family's large estate, 'Chelsea.' Designed by Alexander Jackson Davis, the 36 elegant Greek Revival brownstone townhouses became a very fashionable address for the 19th and early 20th century. The homes had considerable front yards, an oddity for Manhattan. In 1929 the descendants of Clement Clarke Moore leased the property to the Henry Mandel Companies, who demolished the 1845 structures and constructed a massive complex. The 10 central buildings and four corner structures were designed with Tuscan influences by the firm of Farrar & Watmough. The completed buildings were the largest apartment building in the world with 1665 apartments.

(1930-34; Farrar & Watmough) London Terrace Apartments comprises 14 connected 16- and 20-story buildings occupying the perimeter of an entire city block around two generous courtyards. Developed by Russian-born real estate magnate Henry Mandel, they were built in just two years at a cost of $6 million, included 1,670 units, and boasted an indoor pool, gymnasium, dining room, children’s play area, and roof terrace simulating the deck of an ocean liner, from which residents could see actual passenger ships docking at the Hudson River piers just blocks away. Of main appeal were the courtyards, a garden oasis in the middle of the city. Farrar & Watmough designed the buildings as a unified whole, enlivening the monolithic brick and terra-cotta facades with fanciful gargoyles and motifs from North Italian Romanesque, Gothic, and Renaissance architecture. “London Terrace” was borrowed from the row of 36 Greek Revival-style brownstone rowhouses demolished to make way for the new development. According to Mandel’s 1942 obituary, London Terrace “was hailed as the largest multifamily building unit in New York” at the time of its completion.

The early fight against fascism in the United States predates WWII and started in the city with a huge march for May Day in 1934. The Forward was there to march, and also to cover it in all its excitement and color.

In 1750, British naval officer Thomas Clarke bought a Dutch farm to create his retirement estate, named “Chelsea” after the Royal Hospital Chelsea in London. His property extended from approximately Eighth Avenue to the Hudson—its shore ran roughly along today’s Tenth Avenue—between 20th and 28th Streets. The estate was subdivided in 1813 between two grandsons; Clement Clarke Moore received the southern half below 24th Street while his cousin, Thomas B. Clarke, inherited the northern section. The two halves developed distinctly different characters due to the split. Today, Chelsea contains a variety of historic architecture, including some of the city’s most intact nineteenth-century residential blocks, significant commercial buildings, and industrial complexes near the Hudson River.

Three examples of very dense high-rise housing developments suggest how the private market might have rebuilt parts of Manhattan for the middle class if the real estate boom of the late 1920s had not ended in the Great Depression. Two were created by the visionary developer Fred French: Tudor City (1927), a 14.5-acre enclave of a dozen towers on E. 42nd Street, and Knickerbocker Village (1934) on the Lower East side, which replaced some of the district’s oldest tenements with modern, but extremely dense, multifamily housing. The other, London Terrace (1930), packed 1,665 units into an avenue-long apartment block in Chelsea. The density of these middle-class developments averaged 463, 800, and 931 persons per acre, respectively. This story is adapted from an exhibition at the Skycraper Museum. The original version can be seen here.

Real estate developer Henry Mandel used high-rise density and collective amenities as a strategy for London Terrace, which stretched between Tenth and Eleventh avenues on W. 23rd Street. To create his behemoth block, Mandel demolished 80 historic row houses and multiplied the stories to 22, with 67 percent land coverage. With this strategy, Mandel housed a comparable density of turn-of-the-century tenements in modern apartments at an average of nearly 931 people per acre. London Terrace became the densest multifamily housing in the city, and garnered rents of $52-$130 per room.
