though mies had emphasized his wish to complete the campus he had begun, commissions from the late 50s onward were given to skidmore, owings, and merrill (som), prompting mies to never return to the campus that had changed architecture the world over. som architect walter netsch designed a few buildings, including the new library that mies had wished to create, all of them similar to mies's style. by the late 1960s, campus addition projects were given to som's myron goldsmith, who had worked with mies during his education at iit and thus was able to design several new buildings to harmonize well with the original campus. in 1976, the american institute of architects recognized the campus as one of the 200 most significant works of architecture in the united states. the new campus center, designed by rem koolhaas, and a new state-of-the-art residence hall designed by helmut jahn, state street village, opened in 2003. these were the first new buildings built on the main campus in 32 years.
