It is faced in red brick and white limestone.","why_significant":"The building is significant under Criterion C as a notable example of turn-of-the-century French-inspired architecture and as work of architects George C. Palmer and Henry Hornbostel. It was the first building on Morningside Heights erected specifically for student residential use. It is one of only three custom-built fraternity houses in the area and the only one still used as a fraternity.","narrative":"Built in 1898-1899 on Riverside Drive in Morningside Heights, this five-story fraternity house was designed for the Alpha Chapter of Delta Psi, a fraternity founded at Columbia College in 1847. The firm Wood, Palmer and Hornbostel produced the design, likely because George C. Palmer was a fraternity alumnus. Red brick with white limestone trim, a steep slate hip roof, French windows, iron balconies and carved brackets reflect the Early French Renaissance style, enlivened by Beaux-Arts cartouches. Columbia had opened its new campus in 1897, and almost no student housing existed nearby. This was the first building on Morningside Heights built specifically for student residence, and it remains one of only three custom-built fraternity houses in the area and the only one still used as one. Inside are a parlor with a marble fireplace, a dining room, a billiard room and a memorial library. The building is largely unaltered and still serves as a fraternity house.","period_of_significance":"1898-1899","architect_builder":"Wood, Palmer and Hornbostel","architectural_style":"Late Nineteenth and Twentieth Century Revivals (Early French Renaissance style with Beaux-Arts sculptural detail)","criteria":["C"],"status_note":"Still in use as a fraternity house and described as largely unaltered, retaining a very high degree of integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.40721-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/96000484.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96000484/703dbf6ded-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96000484/703dbf6ded-1600.webp","licence":"CC BY-SA 3.0","author":"Americasroof","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Delta-psi-alpha-434-riverside.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:Delta-psi-alpha-434-riverside.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75319443","wikipedia":"https://en.wikipedia.org/wiki/Delta_Psi,_Alpha_Chapter_building","wikidata":"https://www.wikidata.org/wiki/Q5254721"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/delta-psi-alpha-chapter-96000484/"}
