In 1907, William G. Kerckhoff, one of the most important industrialists and financiers in California, commissioned the prominent Los Angeles architecture firm of Morgan and Walls to design the William G. Kerckhoff Building, a Beaux-Arts style commercial building located at the northeast corner of Main and Sixth Streets in downtown Los Angeles.

In 1916, an annex was added. In 1933 the Santa Fe Railroad purchased the building and became the major tenant for over 50 years. The adaptive reuse project includes 132 loft apartments and ground floor retail. The project meets criteria for the National Register of Historic Places.
