Bionic architecture

Bionic architecture is a movement for the design and construction of expressive buildings whose layout and lines borrow from natural (i.e. biological) forms. The movement began to mature in the early 21st century, and thus in early designs research was stressed over practicality. Bionic architecture sets itself in opposition to traditional rectangular layouts and design schemes by using curved forms and surfaces reminiscent of structures in biology and fractal mathematics. One of the tasks set themselves by the movement's early pioneers was the development of aesthetic and economic justifications for their approach to architecture.
