The Glass Pavilion is an annex to the Toledo Museum of Art, and contains a world-renowned glass art collection, as well as glass making facilities. Designed by Sanaa of Tokyo, it is the first project built by the firm in the USA. The challenge was to design the gallery layouts, the permanent casework, display systems, and a study storage gallery within the simple architecture of the building. Built almost exclusively of glass, the transparent walls are shaped to gently separate and fluidly connect the museum’s spaces.
