The Commonwealth Building is a 21-story building located in the heart of Downtown Pittsburgh’s Central Business District (CBD). Originally designed by Frederick Osterling as the Commonwealth Trust Bank, the building is a 300 feet (91 m) tall skyscraper in Pittsburgh. It was completed in 1906 and has 21 floors. The iconic Fourth Avenue bank/office building was converted in 2021 to 150 apartments and street-level retail.

NAIOP Pittsburgh Awards 2022 – Multifamily Renovation of the Year

Many in the Pittsburgh region suggest the vacant office buildings downtown should be converted to multifamily properties. This project is a great model for the adaptive reuse of such properties in downtown Pittsburgh.
