Caples, Richard, Building

300 E. San Antonio Ave., El Paso, TX

When completed in 1910, the Richard Caples Building held the distinction of being the first reinforced concrete structure in downtown El Paso. Prior to the widespread use of the new material, Trost exhibited an interest in its structural capabilities with a series of buildings in the early 20th century. This new construction mode, of great interest to the public, was described in detail in local newspapers. A framework of posts and lintels formed of poured concrete reinforced with steel rods was infilled with tile blocks and faced with brick. The decorative trim was executed in what appears to be cast concrete. When completed, the building was claimed to be fireproof. It is speculated that Caples' extensive experience as a masonry contractor may have been a factor in the selection of concrete as a structural material as well as the decision to face the building with brick.

Prominently sited on a corner lot, the original structure rose five stories and provided prime retail and commercial space. A historic photograph shows the ground floor to be occupied by F. W. Woolworth Company. Today the ground floor serves a retail establishment while much of the upper space appears to be unused.

In 1910 Caples announced plans to construct a second building designed by Trost, known as the Posenor Building. The entire multi-storied building was leased to Max Posenor who operated a millinery business from it. The only remains of this structure, which was located diagonally across from the existing Caples Building, are historic photographs; the structure was razed in 1941.
