Thornburg is a small borough in the Chartiers valley where we can find what is probably the best group of Shingle-style houses in the Pittsburgh area. There is some good evidence that most of them were designed by Edward M. Butz, an architect whose most famous work is the Western Penitentiary. The Shingle style is rare in Pittsburgh, and though the houses are in a wide variety of forms, they share certain quirks—the second floor overhanging the first, the use of masonry for the first floor and shingles above, the exaggerated eaves—that suggest the hand of one architect in the different designs.
