The Pittsburgh Plate Glass Enamel Plant is an Art Moderne-styled factory in Milwaukee, Wisconsin, built in 1937 by the Pittsburgh Plate Glass Company.

[1] The plant was constructed as part of the expansion of the paint and varnish division of what is now PPG Industries based in Pittsburgh.

The building is four stories, 200 feet long, with a brick-clad exterior and a graceful glass tower at the northwest corner.

Hallmarks of the Art Moderne style are the simple, smooth shapes and curves resembling an airplane and the independence from any historic architectural styles.

[2] Renovated in 2008 for commercial and business use, the four-story building houses offices for Knight-Barry Title Group, and the headquarters for data security and compression company, PKWARE.
