Design of the Marathon County Main Public Library involved the preservation and expansion of an existing facility. The 43,000 sf addition wraps around and incorporates 26,000 sf of the 1968 portion, which totally disappears in the final design. Details recalling historic Wausau buildings, such as the red brick and concrete masonry bands, are featured. The windows, which form a hierarchy of larger to smaller pieces of glass from the lower level to the attic level, each have a stone head and a sill detailed in stone and red granite native to the area. The Marathon County Library was awarded the “Library of the Year” by the Wisconsin Library Association.
