It also reflects the city's economic and industrial growth, through the Armor Auto Company and Great Southern Life Insurance Company. Its original design combined industrial glass windows, brick and Art-Deco trim with a traditional penthouse.","narrative":"Rising at the corner of Louisiana and Preston in downtown Houston, this complex was built in 1920-21 for the Hogg family. It has three stair-stepped blocks of reinforced concrete: a seven-story corner building, a three-story center section and a one-story garage on Prairie. Industrial-style windows, red brick and white cast stone trim gave the original design a geometric, Art-Deco character. On the roof sits an 18-room penthouse used as offices for Will Hogg and his family, with a separate oval solarium. The lower floors housed the Armor Auto Company, and Great Southern Life Insurance Company occupied the upper offices for decades. The buildings matter because of William Clifford Hogg, whose work in city planning, conservation, art and civic reform shaped Houston. A 1963 renovation covered most of the exterior with enamel panels, but the original walls survive behind them. The penthouse remained largely unchanged, and restoration was planned.","period_of_significance":"1900-","architect_builder":"Charles E. Barglebaugh and Lloyd R.
