It is also an important work of the architectural firm Starrett & Van Vleck. Its tenants included shipping-related businesses and the maritime architects Gibbs & Cox.","narrative":"Rising 32 stories near the lower tip of Manhattan, 21 West Street is an Art Deco skyscraper built in 1929-31 and designed by Starrett & Van Vleck. It is a steel-frame building faced in yellow, orange and red ironspot brick laid in geometric patterns, with ziggurat setbacks, glazed corner windows and a street-level loggia with bronze panels. Inside, the vestibule, lobby and elevator banks keep travertine walls, terrazzo floors, decorative metalwork and nautical motifs, including a marble mosaic map of lower Manhattan. It was built as a speculative office tower by the 21 West Street Corporation during the downtown redevelopment of the period, drawing tenants from shipping-related trades such as importers, exporters, shipping companies, maritime lawyers and the architectural firm Gibbs & Cox. It is valued as an example of the skyscraper boom and of Art Deco commercial design. The exterior retains a high level of integrity, while the upper floors have been gutted and are being converted to apartments.","period_of_significance":"1929-31","architect_builder":"Starrett & Van Vleck","architectural_style":"Moderne Movement: Art Deco","criteria":["A","C"],"status_note":"Exterior has a high level of integrity and the Art Deco lobby remains; the upper floors were gutted and are being renovated as apartments.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.050747-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/99000316.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/99000316/9102403f09-800.webp","url_1600":"https://nationalhistoricalregister.com/media/99000316/9102403f09-1600.webp","licence":"CC BY-SA 3.0","author":"Gryffindor","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:20_West_Street_001.JPG\" rel=\"noopener\">Gryffindor</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:20_West_Street_001.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75319321","wikipedia":"https://en.wikipedia.org/wiki/21_West_Street","wikidata":"https://www.wikidata.org/wiki/Q8772080"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/building-at-21-west-street-99000316/"}
