Its height and form directly reflect changing city zoning rules, from the 200-foot cap to the 1922 addition and the 1925 tower. It also shows Sullivanesque design with distinctive low-relief terra cotta ornament.","narrative":"Rising thirty-six stories at 11 South LaSalle Street in Chicago's Loop, this office skyscraper was built between 1913 and 1915 by Holabird and Roche, with five stories added in 1922 and a slender tower added in 1925. Its buff brick and glazed terra cotta facades carry low-relief ornament in the Sullivanesque manner, including grotesques, lions, cherubs and scallop motifs, while the tower's upper floors show Art Deco influence and house a bell tower. The building was commissioned by the estate of Leander McCormick as a speculative office venture. Its stages of growth track Chicago's changing height and zoning rules: a 200-foot limit, added stories in 1922, and a tower permitted after the cap was lifted in 1923. These qualities led to its recognition as an excellent local example of early twentieth-century skyscraper design. The exterior is sooty and its ornament has deteriorated in places, and the ground floor and lobby were remodeled in 1984.","period_of_significance":"1914, 1925","architect_builder":"Holabird and Roche and Rebori, Dewey, Wentworth, and McCormick","architectural_style":"Late 19th and Early 20th Century American Movements: Sullivanesque","criteria":["C"],"status_note":"Still in commercial office use; the exterior is described as in poor condition, sooty and with deteriorated terra cotta ornament, and the ground floor and lobby were remodeled in 1984.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.186404-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/35/8921/28892135/content/electronic-records/rg-079/NPS_IL/07001238.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07001238/d2cc3d626d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07001238/d2cc3d626d-1600.webp","licence":"CC BY-SA 3.0","author":"TonyTheTiger (t/c/bio/WP:CHICAGO/WP:LOTD)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:20080402_Roanoke_Building.JPG\" rel=\"noopener\">TonyTheTiger (t/c/bio/WP:CHICAGO/WP:LOTD)</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:20080402_Roanoke_Building.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892135","wikipedia":"https://en.wikipedia.org/wiki/Roanoke_Building","wikidata":"https://www.wikidata.org/wiki/Q7339772"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/lumber-exchange-building-and-tower-addition-07001238/"}
