In 2009 Lohan Anderson was commissioned by the Public Building Commission of Chicago to develop design guidelines and a building program for the design of prototype branch libraries to be located throughout the city. The primary objectives were to establish standards for egalitarian representation of the Library throughout the city; set standards for practical and economical means and methods of operation of the library facilities; and the incorporation of sustainable design.

Three library prototypes were developed:  Prototype A is a single story public library branch of 16,000 to 18,000 sf; Prototype B is a single story public library branch of 8,900 sf; and Prototype C is a two story public library branch of 17,000 sf. Design guidelines include space programming, site design, building systems, interior design, and sustainable design criteria.
