Answer
Neoclassical and Picturesque are the two architectural styles that characterize Nash's work. Neoclassicism emphasizes symmetry, order, and geometric forms inspired by ancient Greek and Roman architecture. Picturesque, on the other hand, embraces irregularity, asymmetry, and the incorporation of natural elements, creating a more romantic and picturesque effect. Nash's designs often blended these styles, resulting in buildings that were both elegant and charming.
