We normally associate the Commonwealth Building with the Pietro Belluschi-designed Equitable Building on SW 6th between Washington and Stark Streets. This Commonwealth Building stood on the southwest corner of SW 6th Avenue and W Burnside. I’m guessing this was demolished during the Burnside widening project of the early 1930s. I believe that’s the Broadway Hotel (now Helen M. Swindells Building) across Burnside reflected in the window.
