Two floors of the W. K. Hancock Library at the Australian National University (ANU) were refurbished in 2011 as part of a cooperative project between the library and the College of Science. The refurbishment, costing $5 million, was part of a much larger exercise involving the construction of four new science buildings around the Hancock Library. The project was designed to add small group teaching rooms to the university's stock, as well as student learning and network spaces, together with group and individual study areas, laptop facilities, and videoconferencing rooms. Emphasis was given to flexibility in use of the space, a mix of study areas and furniture, use of "milling" space, ease of access, and security.
