400 SW Sixth Avenue is an eleven-story office building in Downtown Portland in the U.S. state of Oregon. Originally known as the First National Bank Building, it opened in 1960 as a six-story bank building. The 139-foot (42 m) tall mid-rise contains 216,108 square feet (20,077.1 m2) of space, with retail on the ground floor. From 1995 to 2016 the primary retail tenant was Camera World.
First National Bank of Oregon announced it would build a new headquarters building in 1957, with the contract to build the structure going to Hoffman Construction Company. The planned $3.5 million, five-story building was designed by Stanton, Boles, Maguire & Church and was to have 100,000 square feet (9,300 m2) of space. The building was to be on the site of the Century Theater and Lafayette Building, and would also require the demolition of part of the bank's existing headquarters.
Construction began in December 1957 on what was to be a two-phase project, in which an initial five-story building would be built to allow the bank to move before its existing 1923 structure was demolished. A second five-story building would then be built in the footprint of the old bank building at SW 6th and Stark. In March 1958, erection of the steel frame began, with plans to have the entire project completed in August 1960. The curtain wall began going up in November 1958, and consisted of glass mosaic squares, becoming the first building in the Northwest to use this new type of panel.
In September 1959, the first of the two buildings opened. The exterior mosaic squares were Italian blue and mounted in wall sections made of aluminum. The interior utilized walnut and light marble trim, and included what was believed to be the largest piece of carpet ever laid in the Pacific Northwest at that time, which was installed by Meier & Frank. Construction then commenced on the second structure, and the combined building opened in September 1960. On the ground floor, the plans called for the new building to be connected to First National's former headquarters building, a three-story structure built in 1916, which continued to house the main public branch, facing SW 5th Avenue. That building still stands and is listed on the National Register of Historic Places as the First National Bank.
