Made of native sandstone hauled from a nearby creek, this house was built in 1886 for the manager of the LS Ranch owned by W. M. D. Lee and Lucien B. Scott. Stonemason Tom Nolan designed it, and the twin bunkhouse facing it, from a picture on the Arbuckle Coffee sack. Former Tascosa Sheriff Jim East was first ranch manager to live here. In 1939 Jack Mansfield bought the property and in 1950 enlarged the house, which is still owned by the family.
