Roquemore.","why_significant":"The house is significant locally under Criterion C in the area of Architecture as a well-crafted American Four Square dwelling with Prairie School and Classical Revival influences. It reflects the early 20th-century shift away from Victorian design and the vernacular Prairie School trend in Amarillo. It also has ties to the work of early Amarillo architect Otho G. Roquemore and to later owner John B. Gilvin, a prominent local real estate figure.","narrative":"Built in 1907 at 1500 South Buchanan Street in Amarillo, this 2 1/2-story frame house follows an American Four Square plan with a low hipped roof, weatherboard siding and a cast concrete block foundation. A wide one-story porch wraps from the east front to the north side, carried by grouped Doric columns, with a pediment over the entrance and gable dormers with fanlight windows. Inside, the house keeps an elaborate stairway, fine tracery and detailed fireplace mantels. William F. and Mary Jons, a realty company owner and his wife, had it built, and Otho G. Roquemore designed it, with William C. Townes as contractor. Roquemore was one of Amarillo's first established architects. The house reflects the move from Victorian ornament toward simpler early twentieth-century design, blending Prairie School horizontality with modest classical details. Later owners included John B. Gilvin, a real estate developer involved in reviving the Tri-State Fair, whose family held the house until 1962.","period_of_significance":"1907","architect_builder":"Roquemore, Otho G.
