In 1911, Rockwell Brothers and Co. purchased land from the Pecos and Northern (part of the Santa Fe) Railway for the construction of a lumberyard to serve the new town of Slaton. This two-story vernacular structure was then erected as an office, with living quarters above for the manager and his family. Robert W. Parker was the first manager to occupy the building, which served as the main office until Rockwell closed its Slaton operation in 1941. Recorded Texas Historic Landmark - 1986
