The Brooks Building is a high-rise building in Chicago's commercial core, the Loop. It was built 1909–1910, in the Chicago School architectural style. An early example steel-framed high-rise building, the structure was commissioned by Peter Brooks and Shepard Brooks and designed by architects Holabird & Roche. The building was designated a Chicago Landmark on January 14, 1997. It was also determined eligible for listing in the National Register of Historic Places (NRHP) on October 8, 1982; however, it is not formally included in the NRHP due to the wishes of the property's owner.
