It was designed and built by Sanguinet and Staats for Dr. Bacon Saunders.","why_significant":"The nomination presents it as Fort Worth's version of the large Flatiron buildings in New York and Chicago. It is a good example of the work of the architects Sanguinet and Staats, who were prominent across the Southwest. It also shows characteristics of the Chicago School and is regarded as a local landmark.","narrative":"Rising seven stories above a basement at 1000 Houston Street in Fort Worth, this commercial building follows the wedge shape of its lot, giving it the flatiron form. Built in 1907 of reinforced concrete over a steel frame and faced with brick, it has a two-story base, a five-story body and a heavily ornamented cast-iron cornice. Piers rise through six bays on each wide facade to arches at the top, in the manner of Louis Sullivan, and contrasting brick lozenges decorate the walls. Sanguinet and Staats, a firm that designed courthouses, schools, banks and department stores across Texas and beyond, built it for Dr. Bacon Saunders, a surgeon and medical educator, who wanted offices for himself and other doctors. The building was listed because it is Fort Worth's answer to the flatiron towers of New York and Chicago, shows Chicago School traits, and is a good example of the firm's work. It was also recorded as a Texas Historic Landmark in 1970.","period_of_significance":"20th Century (specific date 1907)","architect_builder":"Sanguinet and Staats (Marshall R.
