Its clapboard walls rise to a gable roof, and the symmetrical central block is fronted by a Classical portico with paired, monumental Ionic columns on pedestals beneath a triangular pediment. Behind the portico, a full-width one-story porch with Tuscan columns and a simple stick balustrade supports a second-floor balcony. Windows are eight-over-one, and the main entry has side lights and a transom. One-story wings were added after 1931, set back from the front facade and detailed to match the main house. The house is considered a good example of upper-class housing in the Classical Revival style. It stands in a neighborhood near downtown that was fashionable after the turn of the century and now supports commercial uses. Since the additions are sympathetic, the building remains a significant local architectural resource. Its condition is described as good.","period_of_significance":null,"architect_builder":null,"architectural_style":"Classical Revival","criteria":["C"],"status_note":"Physical condition is listed as good, with the site original and sympathetic additions; the residence sits in a residential area zoned commercial.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:21.107011-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/51/9701/40970151/content/electronic-records/rg-079/NPS_TX/88002602.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40970151","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q31818337"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/tom-green-county/monogram-square-88002602/"}
