The Diamond Building, at Fifth and Liberty Avenues, is uniquely shaped as an irregular pentagon, one of the many buildings forced into odd shapes by the colliding property grids along Liberty Avenue.The building was designed by MacClure and Spahr, a Pittsburgh firm that gave us several other distinguished buildings, including the Union National Bank building on Fourth Avenue.
