Expressionism evolved from the work of avant garde artists and designers in Germany and other European countries during the first decades of the twentieth century. Key features of Expressionism are:
- distorted shapes
- fragmented lines
- organic or biomorphic forms
- massive sculpted shapes
- extensive use of concrete and brick
- lack of symmetry
- many fanciful works rendered on paper but never built
