Posvar Hall was designed by a consortium of architects, including Louis Valentour of Johnstone Newcomer & Valentour, who worked under the watch of university consultant
Max Abramowitz. Construction began in 1975 and was completed in 1978 with the dedication occurring on October 19, 1978. The building sits on the former site of
Forbes Field baseball stadium and beside the university's
Hillman Library on the corner of Schenley Drive and Roberto Clemente Drive, with Bouquet Street running along its west side. Enclosed passageways connect Posvar Hall to
David Lawrence Hall, the
Barco Law Building, and the
Litchfield Towers. Posvar Hall was designed in the
Brutalist style and is constructed with concrete with a limestone exterior. Its height was limited to five stories so it would not compete with
The Carnegie Institute directly across
Schenley Plaza. Construction costs exceeded $38 million (equivalent to $ million in ). Its floor space slightly exceeds that of the
Cathedral of Learning. It has 2,000 windows, 574 offices, 30 seminar rooms, three lecture halls, one mile of corridors, and nearly 500 parking spaces in a two-level garage below the facility. The central area of the interior space is called the Galleria and contains various artwork including
Virgil Cantini's mural
Enlightenment and Joy and one of
Samuel Pierpont Langley's
aerodromes. Escalators transport individuals between floors. ==Forbes Field==
