The Frick Building was built in 1902 and is one of the nicest, most opulent office buildings in the city. The architecture inside is stunning. Built by Henry Clay Frick the building originally rose 20 feet above ground level, but rose to 21 stories when "The Hump" on Grant Street was removed. What was once the basement floor became the lobby, and the former ground floor became the Mezzanine.

For a short time, the Frick Building was the tallest structure in the city. The Frick Building is the home of some of the top legal eagles in the city of Pittsburgh. The landmark structure is well situated for those in the legal profession, located across the street from the County Courthouse on Grant Street.

Other buildings built by Henry Clay Frick are the 19-story Frick Annex Building (1906), the 23-story William Penn Hotel (1916) and the Union Arcade (1917), now known as the Union Trust Building.
