It later housed the New World Foundation.","why_significant":"The nomination argues the house is an early twentieth century adaptation of the Federal idiom and an inventive solution for a long, narrow corner plot. It is also an unusual example of the work of architect Ernest Flagg, built for a descendant of the prominent Morris family.","narrative":"Built in 1914 at 100 East 85th Street, this brick townhouse with stone trim was designed by Ernest Flagg for Lewis Gouverneur Morris, a stockbroker descended from a family prominent in colonial New York and New Jersey. The lot is only a little over twenty-five feet wide on Park Avenue and eighty-two feet long on 85th Street. Flagg met the challenge by making the building look like two houses separated by an open court, joined by a rear wing holding a broad staircase with landings at each half-level. The exterior draws on Federal architecture through its plain brick walls, fan and quadrant windows, and steep gabled roof with dormers, while the gable ends recall Dutch examples. The split-level plan and tall, narrow massing mark it as twentieth century work. Interiors include paneled walls, fluted pilasters and rich moldings. The house later became the home of the New World Foundation with little change to its fabric.","period_of_significance":"1914","architect_builder":"Ernest Flagg","architectural_style":"Neo-Federal (early twentieth century Federal/Colonial Revival influence)","criteria":[],"status_note":"Occupied; the form says it was adapted without substantial change to a new public purpose as the New World Foundation building, with an altered interior and unaltered exterior.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:40.095594-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/77000960.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/77000960/4e3172554b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/77000960/4e3172554b-1600.webp","licence":"CC BY-SA 3.0","author":"Americasroof","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Morris-house-100e85.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:Morris-house-100e85.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75319742","wikipedia":"https://en.wikipedia.org/wiki/Lewis_G._Morris_House","wikidata":"https://www.wikidata.org/wiki/Q6536571"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/morris-lewis-g-house-77000960/"}
