Businessman Tye Yates Hill built this diminutive Mission-styled building to house the offices of a company dealing with a rare deposit of high-quality granite. The Alamo parapet on the facade and the two-stage bell-cote ( espadaña), modeled after San Juan Capistrano, are an implicit architectural lesson in Texas history at a time when the Californian mission had displaced the authentic Spanish Colonial heritage as an architectural precedent in Texas.
The block of buildings on Bessemer Avenue to the north of the Cassaday Building illustrate Llano’s growth north of the river, stimulated by the construction there of the railroad.
