It is historically significant for its link to Haverhill's 1889 building boom and its long use as one of the city's largest box factories.","narrative":"Built in 1889 at the corner of River and Swain streets in Haverhill, this three-story brick factory was erected for shoe manufacturing and designed by the local architectural firm of Perkins and Bancroft. It was one of five brick shoe factories raised beside one another between 1889 and 1892 as River Street opened to development. The building uses heavy timber, slow-burning mill construction, with separate stages of shoe production arranged on different floors and linked by a small freight elevator. Steam power came through an underground tunnel from the neighboring Chick Brothers factory. Its principal feature is a granite block inscribed \"Intervale Factory.\" Shoe makers Ellis and Connor first used it, but from 1893 it housed box making, first under John Owens and later the Emerson Box Company. It is considered locally significant for its architecture and its ties to Haverhill's industrial growth. Conversion to condominiums began in 1987, altering windows and interiors.","period_of_significance":"1889-1938","architect_builder":"Perkins and Bancroft","architectural_style":"Late Victorian","criteria":["A","C"],"status_note":"Conversion to twenty-four condominium units began in 1987; most windows were being replaced and the interior subdivided while the nomination was prepared.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:02.355471-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/41/7950/63795041/content/electronic-records/rg-079/NPS_MA/88000958.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000958/8773f73d9d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000958/8773f73d9d-1600.webp","licence":"CC BY-SA 3.0","author":"Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:HaverhillMA_IntervaleFactoryBuilding.jpg\" rel=\"noopener\">Magicpiano</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:HaverhillMA_IntervaleFactoryBuilding.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795041","wikipedia":"https://en.wikipedia.org/wiki/Intervale_Factory","wikidata":"https://www.wikidata.org/wiki/Q6057311"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/intervale-factory-88000958/"}
