What is kopper building pittsburgh?

The Kopper Building is a historic office building located in downtown Pittsburgh, Pennsylvania. It was built in 1929 and stands 475 feet tall with 35 floors. The building was designed by architects Graham, Anderson, Probst & White, and is constructed in a Gothic Revival style with Art Deco elements.

Originally built for the Koppers Company, a multinational corporation that produces chemicals and carbon compounds, the building served as their headquarters until 1988. After Koppers moved to a new location, the building fell into disrepair and was ultimately acquired by the PNC Financial Services Group.

In 2001, PNC completed a major renovation of the building, which included modernizing the interior and restoring its historic exterior. The building now houses a mix of office and retail space, and is a prominent landmark in the Pittsburgh skyline.

The Kopper Building is listed on the National Register of Historic Places and is considered one of the most significant Art Deco buildings in Pittsburgh. It has also been recognized for its energy efficiency and sustainability efforts, earning LEED Gold certification.
