Henry Hornbostel's Porter Hall/Baker Hall

A photo tour of Carnegie Mellon University's Porter Hall/Baker Hall, the work of architect Henry Hornbostel from 1905-1914. Architect Naomi Yoran, who designed the 2002 addition to the connected halls, gave me a guided tour and showed how the new addition was created to blend in with Hornbostel's original design. Connecting the two structures is a glass, modern "bridge," from which distinct details of Hornbostel's design can be viewed up close. Details include a spectacular, almost Art Nouveau Guastavino-tile covered curved staircase; and sconced lighting in wide corridors creating ceiling light patterns, steel-reinforced corners and doorways, with doors recessed. The new addition, unlike the original buildings, has a basement, where the Giant Eagle Auditorium was placed. Several pyramidal skylights admit light into the lobby of the basement area. At the top of the round stairway I found two antique proof presses, relics of the Carnegie Institute's printing school. It will take a long time to exhaust the fascinating geometries of this building, just one of Hornbostel's Pittsburgh treasures. Thanks to Naomi Yoran for the guided tour!
