Hedrick.","why_significant":"The nomination argues local significance in Commerce, because the building was financed to house oil-industry tenants during Fort Worth's early twentieth-century growth. It also argues significance in Architecture as an early example of Hedrick's Commercial Gothic style, with vertical pilaster strips and stone ornamentation including owl carvings.","narrative":"Rising 14 stories at the corner of Throckmorton and Sixth streets in downtown Fort Worth, this 1927 office tower was designed by architect Wyatt C. Hedrick and financed by the Dulaney-Johnston Investment Company to house companies tied to the booming oil industry. Brick over a steel frame, it carries Gothic-inspired stone ornamentation on its two street-facing elevations, including narrow pilaster strips, shield-and-banner panels and carved owls with spread wings, while the other two sides are plain brick. For decades it held oil firms such as Gulf Oil, along with lawyers, other professionals and ground-floor shops. It later carried the names Life of America Building, Schick Building, Finevest Building and Executive Plaza Building. A 1969 modernization removed crockets, original stone and windows, but a restoration begun in 2006 returned a stone base, double-hung windows and a copper awning. It was listed for its local importance in commerce and architecture.","period_of_significance":"1927-1959","architect_builder":"Wyatt C.
