Located adjacent to a historic house and landscape, Louisville Free Public Library’s third regional library brings service to an outlying region of the city. Conceived as a pavilion in a park, the building offers sweeping views of the park and historic site. It features a special technology-driven classroom, highly flexible reading room, makerspace with audiovisual lab and demonstration kitchen, and a college corner in the teens’ area. A column-free interior, multi-function access flooring, and rooms enclosed by movable furnishings support adaptability to meet perpetually evolving library demands and ambitions. Sustainable design strategies contributing to the building’s LEED-NC v.3 Gold certification include siting the building to take advantage of natural daylight and a geothermal mechanical system, among numerous others. Circulation for the first month of operation broke the library system’s previous record by 25%.
