On the corner of Broadway and 11th Street in downtown Oakland is the Key System Building, a seven-story classic Beaux-Arts building built in 1911 that’s been vacant since the 1989 Lomo Prieta earthquake. This building first housed Amadeo Giannini's Bank of America, and later became the headquarters for Key Systems. In 1981, the building was placed on the National Register of Historic Places.
The new 18-story tower reflects an overall architectural composition between the old and new. The thoughtful design, in which the new tower is cantilevered over the Key System Building, is the result of close collaboration and careful planning with the Oakland Historical Alliance, Office of Historic Preservation, and City Planning committees. Neutral glass fins on the outer envelope are embedded with metallic fabric, providing the new tower with a rich, textural façade that responds to the ornate, yellow-brick exterior of the Key System Building, and adds another dynamic dimension to the Oakland urban fabric.Slated for completion in 2020, 1100 Broadway marks an exciting, new turn in Oakland's thriving downtown landscape, and sets a bold, new standard for the seamless integration of old and new architecture.
