Renovations were undertaken from 2009 to 2014, which saw the building expanded to its present size with a transparent glass cube built onto the structure; the glass cube holding an expanded lobby that included a shop and café. The design of the cube is reminiscent of the original proposal submitted by Moriyama in 1973. Several social spaces were built into the library during the renovations, including an event centre and the special collections rotunda. The revitalization efforts were led by Moriyama & Teshima Architects, the successor architectural firm to Raymond Moriyama Architects.
