The new building houses four other community organizations (MCAT, Families First Learning Lab, the University of Montana SpectrUM Discovery Area, and the University of Montana Living Lab) to create a library, museum, and science and community center that blends Missoula’s rich heritage with world-class innovations all under one roof. The design process involved an intensive week-long visioning session with leadership from the library and partner organizations to establish project goals and guiding principles. The main floor offers a marketplace with a cafe, retail store, new library materials, and the audiovisual collection; a makerspace; MCAT’s high tech production studio, equipment check-out services, and sound booths; a teens’ area; and the University of Montana Living Lab. Focused on children, families, and play, the second floor houses the Hank and Nancy Harrington Children’s Library, Families First Learning Lab, University of Montana SpectrUM Disovery Area, and a mix of collaborative learning spaces shared by the partner organizations. The third floor includes a demonstration kitchen, reference services, fiction and nonfiction collections, a business center, and genealogy center. The top floor provides spaces for public engagement and gathering and access to an exterior patio.
