Sanborn in Amarillo, Potter County, Texas. It was moved in 1922 to its present corner lot at 1311 South Madison Street in the Plemons Addition.","why_significant":"The house is tied to Henry Sanborn, a major early developer known as the \"father of Amarillo,\" and is the only surviving Amarillo property directly associated with him. It is also a late and rare local example of Italianate architecture with some classical detailing. Because it was moved, the form applies the criteria consideration for relocated properties.","narrative":"Built in 1902, this 1 1/2-story frame house in Amarillo, Texas, was the home of developer Henry B. Sanborn and his wife Ellen until his death in 1912. It has a center-passage plan, a low pyramidal roof with wide bracketed eaves, dentils and modillions, and a full-width porch with slender Ionic columns. The house originally stood on a full block near 5th and 6th avenues. After auction in 1922 it was moved to South Madison Street, where the cupola, a chimney and a weather vane were removed. Sanborn, a barbed wire promoter and ranch partner of Joseph Glidden, promoted the townsite that became Amarillo's central business district. This is the only surviving Amarillo property directly tied to him. It is also considered a late and rare local example of Italianate design. A rear outbuilding is noncontributing.","period_of_significance":"1902-1912","architect_builder":null,"architectural_style":"Italianate; Classical Revival","criteria":["B","C"],"status_note":"Described as in good condition and retaining integrity, though the central cupola, a chimney and a weather vane were removed in 1922.
