Johnson.","why_significant":"The house is a surviving example of the limecrete concrete construction developed in Seguin by Dr. Richard Parks, and it demonstrates the method's durability. It was also the home of Johnson, an early settler, townsite developer, mill builder and briefly mayor of Seguin. Originally Greek Revival in style, it is one of about twenty-five extant early concrete buildings in the town.","narrative":"Built of poured lime-and-gravel concrete, this two-story house at 761 Johnson Avenue in Seguin was begun in 1847 by Colonel Joseph F. Johnson, who had come from Virginia in 1844. Slave labor built it at a reported cost of $10,000. The walls were formed in boards and raised about a foot at a time, using gravel and lime from the Guadalupe River bottom, a method developed in Seguin by Dr. Richard Parks. Tobias Meineger is credited as architect. The house originally showed Greek Revival features, including a two-story columned portico, which were removed or altered after World War II when it became apartments. Inside, a central hall plan, walnut woodwork and a fine stairway survive. Johnson laid out the townsite of Guadalupe City, built Seguin's first grist mill, flour mill and cotton gin, and served as mayor before dying in office in 1856. The house stands as one of Seguin's surviving early concrete buildings.","period_of_significance":"1847-1854","architect_builder":"Tobias Meineger (attributed architect); Dr. Richard Parks (contractor for many Seguin concrete buildings)","architectural_style":"Greek Revival (original facade influence)","criteria":[],"status_note":"Described as in good condition and unaltered on the form; converted to apartments after World War II, with later efforts by owners to preserve and restore it.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:18.786829-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/23/9722/40972223/content/electronic-records/rg-079/NPS_TX/78002940.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40972223","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110002090"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/guadalupe-county/johnson-joseph-f-house-78002940/"}
