The building, located at 350 South Fifth Street, is an example of Richardsonian Romanesque architecture. The design is based upon Henry Hobson Richardson‘s Allegheny County Courthouse in Pittsburgh, Pennsylvania. Washington School, the first schoolhouse in Minneapolis west of the Mississippi River, was demolished to make way for the new building. Groundbreaking took place in 1889, and the cornerstone was laid (a story off the ground) in 1891. Construction did not officially end until 1906, although the structural exterior was essentially complete by the end of 1895. The county began moving in to its side (4th Ave.) in November 1895, while the city (3rd Ave.) side was not occupied until December 1902. Cost was about $3,554,000, which works out to 28¢ per cubic foot ($10/m³).
