Expressionist Architecture

At the turn of the 20th century, a movement known as expressionism swept across the world's architectural minds. This style relies heavily on bulky, unusual massing and generally consists of concrete, steel and glass. These materials were just beginning to be mass produced, making way for innovations spurred on by expressionist imagination.
