The Civic Opera Building is a 45-story office tower (plus two 22-story wings) located at 20 North Wacker Drive in Chicago. The building opened November 4, 1929, and has an Art Deco interior. It contains a 3,563-seat opera house, the Civic Opera House, which is the second-largest opera auditorium in North America. Today, the opera house is the permanent home of the Lyric Opera of Chicago. Samuel Insull envisioned and hired the design team for building a new opera house to serve as the home for the Chicago Civic Opera, as the company was called. The building is shaped like a huge chair, sometimes referred to as "Insull's Throne." Insull directed the chair should face west to signify turning his back on New York. Insull had left a vice presidency at General Electric in New York in 1892, after he was not named its president. Subsequently, he moved to Chicago and became president of Chicago Edison (Commonwealth Edison). Insull selected the architecture firm Graham, Anderson, Probst & White who were responsible for several other buildings in the downtown Chicago Loop. As they did on other occasions, the architects commissioned Henry Hering to produce architectural sculpture for the building. Mary Garden of the Chicago Civic Opera announced on July 15, 1929, that the opera's inaugural season would include the commissioned work of Hamilton Forrest entitled Camille.During the 1950s and 1960s the building was identified by a large "Kemper Insurance" sign, although it was not that company's headquarters. In 1993, the Lyric Opera of Chicago purchased the opera house facilities in the building it had rented for 64 years. In 2012, Tishman Speyer Properties L.P. sold the 915,000 square feet (85,000 m2) office tower portion of the building for $125.8 million to an affiliate of Nanuet, N.Y.-based Berkley Properties LLC.

The Boeing International Headquarters (colloquially known as the Boeing Building and formerly known as the Morton-Thiokol International Building) is a 36-floor skyscraper located in the Near West Side of Chicago. The building, at 100 North Riverside Plaza, is located on the west side of the Chicago River directly across from the downtown Loop. The building was designed with a structural system that uses steel trusses to support its suspended southwest corner in order to clear the Amtrak and Metra railroad tracks immediately beneath it. The building was originally constructed for the Morton Salt Company in 1990, but became largely vacant a decade later after the company was acquired and downsized. Boeing moved their corporate headquarters there in 2001 when they opted to leave Seattle for Chicago. Navteq moved their headquarters to the Boeing Building in 2007. It has also housed offices of Ameritech.. By 2021, with Boeing executives handling political and economical fallout from the Boeing 737 MAX groundings and the impact of the COVID-19 pandemic on aviation, Reuters reported that the shift in priorities rendered the building a "ghost town". Boeing ultimately announced the following year that it would move its corporate headquarters to Arlington, Virginia, where its defense division is located; the division relocated there from St. Louis in 2017.

The Riverside Plaza is considered one of Chicago's finest Art Deco buildings. It was originally known as the Chicago Daily News Building. At the time of its completion in 1929, the Daily News was one of the dominant newspapers in Chicago. The 26-story building helped revitalize the Chicago River and made innovations in engineering and urban design. In the 1920s, the buildings along the river were industrial in nature and butted up against a waterway that was polluted and considered undesirable. This building was the first to develop the Chicago riverfront aesthetically as well as commercially. It was the first American skyscraper with an open-air plaza as part of its design.In 1925, Walter A. Strong acquired the Chicago Daily News from the estate of Victor F. Lawson. Once he became publisher, Strong took immediate steps to build a modern newspaper facility. Lawson had owned a parcel along the river, which is now the site of the Chicago Opera House. Strong thought it too small and instead acquired the air rights over railroad tracks that ran along west side of the river opposite the original site. A year and one-half of meetings were required to reach an agreement between all parties. Once that was settled, Strong sold Lawson’s parcel to the utility magnate Samuel Insull, with the understanding that he construct a building that would include a new home for the Opera. Strong commissioned Holabird & Root to design a modern structure that would house 2,000 Daily News employees and provide studio space for his radio station, WMAQ. The building’s bold design and Art Deco façade were widely regarded as shot fired at the Chicago Tribune, which operated out of the Tribune Tower, a large Neo Gothic building on North Michigan Avenue completed in 1925. Inside, the building featured a much-admired mural by John W. Norton. It was dominated by diagonal lines, and divided into three sections: Gathering the News, Printing the News, & Transporting the News. In the fall of 1993, it was removed and put into storage, where it has remained. Outside, it had bas-reliefs depicting Benjamin Franklin, Charles Anderson Dana, Horace Greeley, Joseph Pulitzer, Samuel Bowles III, James Gordon Bennett and Joseph Medill and a fountain honoring Victor Lawson. The Chicago Daily News Building was completed in June 1929 at a cost of $8 million. During the dedication ceremony, President Herbert Hoover pressed a button that started the presses. The Daily News ceased publication in 1978. Although the building has since been renamed Riverside Plaza, according to the Tribune’s architecture critic, the Daily News Building remains, “one of Chicago's finest examples of Art Deco architecture and a path-breaking work of engineering and urban design.”A ramped concourse through the south side of this building now serves as the main entryway to the Ogilvie Transportation Center in Citigroup Center. This concourse was originally the main lobby, with an even floor in place of the ramp up to the bridge at Canal Street.

The Gogo Building, formerly known as the River Center, is an 840,000-square-foot (78,000 m2) commercial building located at 111 N. Canal Street in the West Loop community area of Chicago, Illinois.

Other tenants include Twitter, Uber, Vivid Seats, SAP Fieldglass, Potbelly Sandwich Works and Kin + Carta.

Randolph/Market was a station on the Chicago "L"'s Lake Street Elevated, serving its Market Street stub between the main line and the Market Street Terminal. It was the only intermediate station on the Market Street stub, and on any of Chicago's terminal stubs. It opened with the rest of the Elevated on November 6, 1893. After the Loop was built downtown, only overflow and express services ran on the Market Street stub. The stub, and Randolph station, closed on April 5, 1948, and was demolished shortly afterwards.
