An abundance of Austin limestone, Texas flagstone and other materials such as round river rocks, were employed for some of the buildings to help create this "old-fashioned" look. A total of 85,000 tons of stone were used to complete the project. It was important that the project implement stone and all other resources, such as plant and wildlife, indigenous to the state of Texas. Austin limestone, quarried in large blocks, was used for the building facades of the Wells Fargo Bank and part of the General Store. The blocks had a nominal height of 8 to 10 inches and varied in length. The stones were irregularly laid in a brick pattern for one building, and were randomly laid in various size pieces for the other building's exterior.
The techniques involving the placement of the stone and the detailing and mortaring, depict an old-fashioned style of masonry. Struck joints, tool joints and slop joints were all used in various areas on the project.
