The B.L. Stone building cost $23,000 to construct in 1883. It stood at the corner of SW 1st Avenue and Market Street, where the Mercedes-Benz dealership is now. Hawkins’ “The Grand Era of Cast-Iron Architecture in Portland” states it was demolished in 1968 by the Portland Development Commission but I suspect it was earlier than that, as two 1964 aerial photos on this site show the building already gone. This photo dates to 1953.
