Hedrick. (The listing metadata places it in Houston, but the form itself locates it in Fort Worth.)","why_significant":"The building is significant locally under Criteria A and C. It reflects the oil industry's influence on Fort Worth's commercial growth, housing oil-related firms for decades. It is also an early example of Hedrick's Commercial Gothic style, with stone owl carvings and vertical pilaster strips.","narrative":"Rising 14 stories at the corner of Throckmorton and Sixth streets in downtown Fort Worth, this 1927 office tower was built to house businesses tied to the region's oil industry. Wyatt C. Hedrick designed it with a brick-over-steel frame and stone ornamentation on its two street-facing sides, including narrow pilaster strips, stone owl carvings and shield-and-banner panels, giving it a Commercial Gothic character. The Dulaney-Johnston Investment Company financed construction, and over the following decades oil companies such as Gulf Oil, along with lawyers and other professionals, leased space, while shops occupied the ground floor. Later owners renamed it the Life of America, Schick, Finevest and Executive Plaza buildings. A 1968-69 remodeling removed the crockets, replaced the windows and swapped the stone base for concrete panels. A restoration that began in 2006 returned the base, windows and awning to their original look. It is recognized for its role in Fort Worth commerce and its architecture.","period_of_significance":"1927-1959","architect_builder":"Wyatt C.
