The Gage Group Buildings consist of three buildings located at 18, 24 and 30 S. Michigan Avenue, between Madison Street and Monroe Street, in Chicago, Illinois. They were built from 1890–1899, designed by Holabird & Roche for the three millinery firms - Gage, Keith and Ascher. The building at 18 S. Michigan Avenue has an ornamental façade designed by Louis Sullivan. It was listed on the National Register of Historic Places on November 14, 1985, and was designated a Chicago Landmark on September 11, 1996. In addition, it is a historic district contributing property for the Chicago Landmark Historic Michigan Boulevard District. The façades of these buildings demonstrate two different approaches to the Chicago School, a design movement that led to the creation of modern commercial architecture. The buildings by Holabird & Roche are straightforward, while the facade designed by Sullivan exemplifies his more expressive approach. The tallest building is known as "18 South Michigan Avenue" and was previously called the Gage Brothers and Company Building. Before the Chicago street addresses were changed in 1909, the building had the address of 130 S. Michigan Avenue. The ornamental flourishes at the top of Sullivan's façade were pushed upwards when four stories were added in 1902 by different architects. This is one of only five buildings in Chicago designed by Louis Sullivan as a solo architect that are still standing. The two smaller buildings to the south are also part of the Gage Group Buildings. The Edson Keith and Company Building is connected to the Gage Building and is located at 24 S. Michigan Avenue. The Theodore Ascher and Company Building is also known as the 30 South Michigan Building.

The Market Street Terminal was a station on the Chicago "L"'s Lake Street Elevated – today part of the Green Line – between 1893 and 1948. The Elevated's original downtown terminus, it opened at the corner of Madison Street and Market Street (modern-day Wacker Drive) on November 6, 1893, alongside the rest of the Elevated. When the Loop was constructed in 1895, the Terminal was required to be demolished but no action was taken. When it closed in 1948, only overflow traffic served it. It was demolished shortly thereafter for the construction of double-decked Wacker Drive.

The First Leiter building (or Leiter I) was a Chicago commercial structure built in 1879 by William Le Baron Jenney. It was renovated and extended in 1888, and demolished in 1972. Jenney designed this building, located at Washington and Wells Streets, as a department store for Levi Z. Leiter. This building marked a significant milestone in architectural engineering: it combined, for the first time, four essential elements of a modern skyscraper in one building. These were: its great height (Leiter I was originally five stories tall, and shortly after expanded to seven stories); an iron skeletal frame; terra cotta fireproofing materials on all of its structural members; and, vertical transportation via elevators. It also utilized a new type of glass in its windows. Although the city building department required Jenney to build one exterior party wall as a traditional masonry loadbearing structure and the floors were of heavy timber construction, the rest of the building was a truly modern innovation.

The Miglin-Beitler Skyneedle was a proposed 125-floor skyscraper intended for Chicago, Illinois, United States, by Lee Miglin and J. Paul Beitler and designed by architect César Pelli. The site of the proposed Skyneedle now is host to a parking garage. If it had been built when it was planned, the 1,999 ft (609 m) tall Miglin-Beitler Skyneedle would have been the tallest building in the world.The tower's plans were unveiled in 1988. The plans would falter due to the post-Gulf War market downturn. Miglin-Beitler held hopes of reviving the project, but these were dashed by the murder of Lee Miglin.The tower would have risen 125 floors and 1,999 feet. It would have had 1.9 million square feet of space (with 1.2 million being office space). It was planned to cost $450 million to construct. As of July 1990, it was tentatively planned to open in 1993.The firm had believed that the observation deck planned atop the tower, as well as the twelve floors of parking at its lower levels, would produce large amounts of revenue. Plans also called for the building to include a two-story health club. Office space in the building would have been marketed to smaller yet prestigious firms. The goal was to attract law firms and other tenants desiring a high-status location, but needing only between 8,000 and 10,000 square feet of office space.There were a number of challenges facing the project before the post-Gulf War economic downturned ultimately doomed it. This included the earlier savings and loan crisis putting in place a stricter regulatory climate for banks and credit unions, which made many financial institutions wary of large real estate projects as investments. Another challenge was that the Chicago real estate market, particularly in its downtown, was "soft". The downtown had an office space vacancy of 14%, which was on the rise. Additionally, millions of additional square feet of office space was already under construction in downtown Chicago, with millions more to open up with Sears moving out of the Sears Tower for a new suburban headquarters. Another challenge that analysts predicted was that larger corporate tenants might avoid the building, as its narrow floorplates would require firms needing larger amounts of office space to locate their offices across several floors. This could prevent the building from attracting large "anchor" tenants.Across Wells Street from the site where the tower was to be built is another Pelli project previously developed by Miglin-Beitler, 181 West Madison Street, which reportedly inspired the general design of the Skyneedle. Visually the upper floors of the Skyneedle do appear to be similar to a stretched 181 W Madison. Across Madison Street from the site where the tower was to be built is 200 West Madison, another building developed previously by Miglin-Beitler.César Pelli also designed the Petronas Towers in Kuala Lumpur. The Petronas Towers have an obvious design reference, with the exception of having round floorplates as opposed to square ones.

111 South Wacker Drive is a high-rise office building located in Chicago, Illinois.. Completed in 2005 and standing at 681 feet (208 m), the 51 story blue-glass structure is one of the tallest in the city. It sits on the site of the former U.S. Gypsum Building, one of the tallest buildings in Chicago to be demolished. Designed by Lohan Caprille Goettsch Architects, the building is noted for its unique parking ramp. The ramp's cyclical form creates a dramatic sloped ceiling for the building's main lobby underneath. The ramp's corkscrew design is reflected outside as well; the pavement follows the radiating lines set inside. The building is also noteworthy for its sustainable design, becoming the first-ever project to be certified LEED-CS Gold by the U.S. Green Building Council.

200 West Madison is a skyscraper in Chicago, Illinois. The building rises 599 feet (182 m) in the Chicago Loop. It contains 45 floors, and was completed in 1982. 200 West Madison currently stands as the 52nd-tallest building in the city. The architectural firm who designed the building was Skidmore, Owings & Merrill, the same firm who designed Chicago's Willis Tower and John Hancock Center and the Burj Khalifa in Dubai. The building was designed with a "sawtooth edge," and incorporates six corners onto the southeast face of the building. Thus, the building has nine corner offices on most of its floors. Originally named "Madison Plaza," the building was proposed to have a twin tower located on the lot situated south of the tower. However, plans for a second tower were ultimately abandoned. Six years later, in 1988, the Miglin-Beitler Skyneedle was proposed for construction on the same lot, adjacent to 200 West Madison. Plans called for 125-story tower that was to rise 2,000 ft (610 m). However, that plan was also eventually cancelled. The lot is now the site of a parking garage.200 West Madison is the location of "Dawn Shadows," a famous black metal sculpture created by Louise Berliawsky Nevelson. The sculpture was brought to the plaza in 1983.
