It was designed by Vertner Tandy, the first African American licensed as an architect in New York State, and it embodies the characteristics of mid-20th century Moderne design.","narrative":"Rising six stories above a basement on a steep Harlem hillside, this apartment building at 17-19 Hamilton Terrace was designed in 1948 by Vertner Tandy and opened in 1951. Beige brick and concrete form its three bays, and curved, projecting concrete balconies mark the center. Dr. Walter Delph and his wife Minette developed it to ease the post-World War II housing shortage for middle-income African American families. It was the first large-scale project by African Americans in New York State to use a Federal Housing Administration mortgage commitment, with the Bowery Savings Bank supplying the loan. Amenities uncommon in the neighborhood included an elevator, basement laundry and a recreation room. Tandy, the first African American licensed as an architect in New York State, died in 1949 before completion, and this was among his last designs. The building still has most of its original character, though doors, windows and roofing were replaced in 1984. Tenants included several prominent Black broadcasters, actors and musicians.","period_of_significance":"1948-51","architect_builder":"Tandy, Vertner","architectural_style":"Modern Movement/Moderne","criteria":["A","C"],"status_note":"Retains a high degree of period integrity and is in good physical condition; still used as a multiple dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:52.563026-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/04001531.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04001531/4dee365377-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04001531/4dee365377-1600.webp","licence":"CC BY-SA 3.0","author":"Americasroof","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Ivey-apartments.jpg\" rel=\"noopener\">Americasroof</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:Ivey-apartments.jpg"},"district":{"nrhp_refnum":"83001727","name":"Hamilton Heights Historic District","url":"https://nationalhistoricalregister.com/districts/new-york/hamilton-heights-historic-district-83001727/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75319650","wikipedia":"https://en.wikipedia.org/wiki/Ivey_Delph_Apartments","wikidata":"https://www.wikidata.org/wiki/Q6098895"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/ivey-delph-apartments-04001531/"}
