Answer
Neoclassical style is a key feature of Nash's designs. This style, inspired by ancient Greek and Roman architecture, emphasizes symmetry, balance, and geometric forms. Nash's buildings often feature columns, pediments, and other classical elements, giving them a sense of grandeur and order. The neoclassical style was popular in the late 18th and early 19th centuries, and Nash's work played a significant role in its development in England.
