The Koppers Tower is an Art-deco skyscraper designed by Graham, Anderson, Probst & White and built between 1927 and 1929, for a reported $5.30 million dollars, in Pittsburgh, PA.

Its precise street address is 436 Seventh Avenue, Pittsburgh, PA. You can also find it on the map here.

At the time of its completion in 1929 the Koppers Tower incorporated solutions that were quite advanced at the time, these included the use of limestone and granite to clad the facade, which was a departure from the brick and terra cotta that were commonly used in buildings at the time. The use of these materials gave the building a more modern and sophisticated look, and helped to set it apart from other buildings in the city.

Architect and team

Graham, Anderson, Probst & White was the architecture firm in charge of the architectural design.

Also known as GAP&W, the firm was founded in 1912 in Chicago, and remained active until 2006, when it finally closed its doors.

GAP&W is not only key in the evolution of Chicago's architecture because of the buildings they designed, which were many and nothing short of cutting-edge for their time, but also because two of their architects, Hubert Burnham and Daniel Burnham, eventually started their own practice, which became Burnham Brothers, yet another of the most influential firms the city has ever seen.

The firm's style evolved according to the times. Their first buildings had clear Beaux-Arts inspirations, but they eventually embraced the arrival of Art-Deco, as well as neogothic and neoclassicism.

Graham, Anderson, Probst & White was in charge of the architectural design, however, architecture is a complex discipline, which usually involves many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the Koppers Tower a reality:

  • Mellon-Stuart as the Main Contractor
  • Andrew W. Mellon as the Main Developer
  • Vincent Nesbert as the collaborating Artist

Architectural Style

The Koppers Tower can be categorized as an Art-deco building.

The Art Deco movement flourished during the 1920s and 1930s, with many historians marking the outbreak of World War II as its final decline. Even though a couple of decades might not seem as much, the Art Deco movement had a great impact on architecture, and it's widely represented in many American cities due to the development boom that happened during that time.

Art Deco marked the abandonment of traditional historicism and the embracement of modern living and the age of the machine. In architecture, that meant leaving behind the ornaments of Beux-Arts and Neo-Gothic buildings and instead favoring simplicity and visual impact through geometric shapes, clean lines, and symmetrical designs. Ornaments were still an important part of the design, but they became bold and lavish, and were often inspired by ancient cultures or industrial imagery, instead of nature.

The Koppers Tower was completed in 1929, right when the Art Deco movement was at its peak, so it kind of went with the trend at that time.

Spaces & Uses

Materials & Structure

The Koppers Tower uses a frame structure made of steel columns and concrete slabs.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade is non-load bearing either, as it is common in frame structure type buildings.

From an aesthetic point of view, the facade features a three-story polished granite base, with the rest of the facade clad in Indiana limestone. The silhouette of the building has a series of setbacks, located on the 21st and 29th levels, and a distinctive castle-like roof made of copper sheets.

The tower, adorned with intricate details, such as carved stone panels and a decorative crown, is set back from the main body of the building, which creates a dramatic effect and emphasizes the building’s height.

The prominent entrance on Seventh Avenue features stone details, brass, and a beautiful square chandelier.

Other materials found at the Koppers Tower include, marble , Italian Cremo, Spanish Rajo Alcante and Tennessee marbles are found in the three-story atrium walls, and bronze, used in elevator doors, clocks and railings.
