Its main building is a one-and-a-half-story frame house with a T-shaped plan, intersecting gables, a corbeled brick chimney and a shed-roof porch with turned posts and jig-cut brackets. A small rear addition is the only noted change. A one-room stone structure, believed to have been a smokehouse, stands just north of the house, and two barns, one board-and-batten and one metal-covered, add to the farm's historic character. The property occupies one of the oldest farmsteads in the Norwegian Settlement and was described as one of the most outstanding late 19th-century farmhouses in the area. A grandchild reported that Norwegian carpenter Johan Nordahl built it after an 1892 fire destroyed the old stone house of Berger and Ann Rogstad, whose foundation is said to remain. The house was unoccupied and in fair condition when documented.","period_of_significance":null,"architect_builder":"Johan Nordahl, Norwegian carpenter (according to a grandchild)","architectural_style":null,"criteria":[],"status_note":"Listed as unoccupied and in only fair condition; the house is virtually unaltered and retains its integrity to a remarkable degree.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:18.648846-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/91/9683/40968391/content/electronic-records/rg-079/NPS_TX/83003123.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40968391","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110000392"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/bosque-county/rogstad-tom-and-martha-farm-83003123/"}
