###Input: From the mid-2000s, the university began a number of multimillion-dollar expansion projects. In 2008, the University of Chicago announced plans to establish the Milton Friedman Institute which attracted both support and controversy from faculty members and students. The institute will cost around $200 million and occupy the buildings of the Chicago Theological Seminary. During the same year, investor David G. Booth donated $300 million to the university's Booth School of Business, which is the largest gift in the university's history and the largest gift ever to any business school. In 2009, planning or construction on several new buildings, half of which cost $100 million or more, was underway. Since 2011, major construction projects have included the Jules and Gwen Knapp Center for Biomedical Discovery, a ten-story medical research center, and further additions to the medical campus of the University of Chicago Medical Center. In 2014 the University launched the public phase of a $4.5 billion fundraising campaign. In September 2015, the University received $100 million from The Pearson Family Foundation to establish The Pearson Institute for the Study and Resolution of Global Conflicts and The Pearson Global Forum at the Harris School of Public Policy Studies.

The first buildings of the University of Chicago campus, which make up what is now known as the Main Quadrangles, were part of a "master plan" conceived by two University of Chicago trustees and plotted by Chicago architect Henry Ives Cobb. The Main Quadrangles consist of six quadrangles, each surrounded by buildings, bordering one larger quadrangle. The buildings of the Main Quadrangles were designed by Cobb, Shepley, Rutan and Coolidge, Holabird & Roche, and other architectural firms in a mixture of the Victorian Gothic and Collegiate Gothic styles, patterned on the colleges of the University of Oxford. (Mitchell Tower, for example, is modeled after Oxford's Magdalen Tower, and the university Commons, Hutchinson Hall, replicates Christ Church Hall.)

After the 1940s, the Gothic style on campus began to give way to modern styles. In 1955, Eero Saarinen was contracted to develop a second master plan, which led to the construction of buildings both north and south of the Midway, including the Laird Bell Law Quadrangle (a complex designed by Saarinen); a series of arts buildings; a building designed by Ludwig Mies van der Rohe for the university's School of Social Service Administration;, a building which is to become the home of the Harris School of Public Policy Studies by Edward Durrell Stone, and the Regenstein Library, the largest building on campus, a brutalist structure designed by Walter Netsch of the Chicago firm Skidmore, Owings & Merrill. Another master plan, designed in 1999 and updated in 2004, produced the Gerald Ratner Athletics Center (2003), the Max Palevsky Residential Commons (2001), South Campus Residence Hall and dining commons (2009), a new children's hospital, and other construction, expansions, and restorations. In 2011, the university completed the glass dome-shaped Joe and Rika Mansueto Library, which provides a grand reading room for the university library and prevents the need for an off-campus book depository.

The University of Chicago also maintains facilities apart from its main campus. The university's Booth School of Business maintains campuses in Singapore, London, and the downtown Streeterville neighborhood of Chicago. The Center in Paris, a campus located on the left bank of the Seine in Paris, hosts various undergraduate and graduate study programs. In fall 2010, the University of Chicago also opened a center in Beijing, near Renmin University's campus in Haidian District. The most recent additions are a center in New Delhi, India, which opened in 2014, and a center in Hong Kong which opened in 2015.

The University of Chicago is governed by a board of trustees. The Board of Trustees oversees the long-term development and plans of the university and manages fundraising efforts, and is composed of 50 members including the university President. Directly beneath the President are the Provost, fourteen Vice Presidents (including the Chief Financial Officer, Chief Investment Officer, and Dean of Students of the university), the Directors of Argonne National Laboratory and Fermilab, the Secretary of the university, and the Student Ombudsperson. As of August 2009[update], the Chairman of the Board of Trustees is Andrew Alper, and the President of the university is Robert Zimmer. In December 2013 it was announced that the Director of Argonne National Laboratory, Eric Isaacs, would become Provost. Isaacs was replaced as Provost in March 2016 by Daniel Diermeier.
