1000 K Street (Woolworth Building Renovation)

Sacramento, CA

The Woolworth store at 10th and K opened in 1959 to much fanfare during the heyday of the J and K Street commercial corridor. The building was Woolworth’s home in Sacramento for many years.  Some years later the building was renovated into the Cosmopolitan. This modernization and update included a cabaret theater, an upscale restaurant and nightclub, office space and parking. Large expanses of the perimeter walls and roof were removed to increase the natural lighting in the building and extensive work was required to remove two of the 22” square concrete columns that interfered with the cabaret theater seating. The building continues to change with the Sacramento landscape and is currently serving downtown diners as a restaurant and offices.
