Pioneer Building (Seattle)  The Pioneer Building is a Richardsonian Romanesque stone, red brick, terra cotta, and cast iron building located on the northeast corner of First Avenue and James Street, in Seattle's Pioneer Square District. Completed in 1892, the Pioneer Building was designed by architect Elmer Fisher, who designed several of the historic district's new buildings following the Great Seattle Fire of 1889. From Seattle's earliest days until the early 1880s, the corner of First and James was the site of Henry and Sarah Yesler's home and orchard, with his steam-powered sawmill located across the way. His home served as the center of social life and hospitality in early Seattle. As Seattle's business district began to grow rapidly in the early 1880s, Yesler moved to his new mansion, designed by architect William E. Boone, three blocks away at 4th and James in 1884. Rather than demolishing his old house and fully redeveloping his property, he moved the house to the back of the lot and filled his First Avenue frontage with displaced buildings purchased and relocated from across the street. He began planning an office block at First and James in late 1888 with the completed elevation drawings by architects Fisher & Clark put on public display that December. Local media proclaimed it would be one of the finest buildings in the country, and the largest north of San Francisco. While the lumber was being cut and contracts for the steel work and terra cotta were still being secured, excavation for the southern half of the building began in mid-February, 1889 with the temporary relocation of several existing structures on the site, followed by their demolition, including the original Yesler home, the following month. Yesler's plan was to construct the southern half of the building first, then finish the northern portion the following building season after payments for recently sold property would be secured. Grading was completed and construction began in May but was soon halted due to a shortage of rough stone that was plaguing the city; only 144 tons of the 800 tons of stone that were ordered for the building could be delivered. Several months after the Great Seattle Fire leveled 32 blocks of downtown and new grades and street widths had been firmly established, Yesler proceeded with the construction of the Pioneer Building. The Pioneer Building is a symmetrical block, measuring . The exterior walls are constructed of Bellingham Bay gray sandstone at the basement and first floor, with red brick on the upper five floors (with the exception of two stone pilasters which extended to the full height of the tower over the main entrance).
