Marshall. It was the third unit of the Edgewater Beach Hotel complex.","why_significant":"The nomination argues the building is significant for its architecture under Criterion C. It is an example of Marshall's work, combining luxury apartment and hotel features in an X-shaped plan with an eclectic Italian Villa/Renaissance treatment. Marshall is described as the designer who set the standard for Chicago's luxury hotels and apartment buildings.","narrative":"Completed in 1928 at 5555 North Sheridan Road in Chicago, this nineteen-story building offered 307 apartments with 1,517 rooms, planned as high-class transient and residential homes that mixed apartment and hotel features. Architect Benjamin H. Marshall gave it an X-shaped plan with forked wing ends to maximize light and lake views. Its reinforced concrete frame is faced with limestone on the lower floors and pink stucco with terra cotta trim above, topped by an octagonal tower. The design blends classical details in an informal Italian Villa and Renaissance manner, echoing the Mediterranean look of 1920s beach hotels and the neighboring Edgewater Beach Hotel. Inside, a two-story butternut-paneled lobby, an indoor pool and a ground-floor shopping arcade survive. Alterations in 1955 removed the exterior urns and colonnades, but most original features remain. It was listed for its architecture as a notable work by Marshall, a leading designer of Chicago luxury apartments and hotels.","period_of_significance":"1928","architect_builder":"Marshall, Benjamin H., Architect","architectural_style":"Classical Revival","criteria":["C"],"status_note":"Still used as multiple dwellings, with some alterations, including 1955 changes by Holabird, Root and Burgee that removed exterior urns, columns and entablature.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.520132-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/66/8919/28891966/content/electronic-records/rg-079/NPS_IL/94000979.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94000979/da2ae4c354-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94000979/da2ae4c354-1600.webp","licence":"CC BY-SA 3.0","author":"Alanscottwalker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Edgewater_Beach,_Chicago.jpg\" rel=\"noopener\">Alanscottwalker</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:Edgewater_Beach,_Chicago.jpg"},"district":{"nrhp_refnum":"95000482","name":"Bryn Mawr Avenue Historic District (Additional Documentation)","url":"https://nationalhistoricalregister.com/districts/illinois/bryn-mawr-avenue-historic-district-additional-documentation-95000482/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891966","wikipedia":"https://en.wikipedia.org/wiki/Edgewater_Beach_Hotel","wikidata":"https://www.wikidata.org/wiki/Q3047559"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/edgewater-beach-apartments-94000979/"}
