Which of the following styles is NOT associated with the Georgian century?

The style that is not associated with the Georgian century is Art Deco. The Georgian era, which spanned from the early 18th century to the early 19th century, is characterized by neoclassical elements and refinement in design, with a focus on symmetry, proportion, and the influence of classical architecture.

Chippendale, Hepplewhite, and Sheraton styles all emerged during or were greatly influenced by the Georgian period. Chippendale is recognized for its elaborate furniture designs, Hepplewhite is known for its lighter, more delicate furniture with straight lines, and Sheraton furniture features elegant, refined qualities. Each of these styles reflects the aesthetic principles and materials that were prominent during the Georgian era, which emphasizes craftsmanship and decorative details.

In contrast, Art Deco, which originated in the 1920s and 1930s, is marked by bold geometric shapes, vibrant colors, and modern materials. It represents a departure from the classical influences that defined the Georgian style, focusing instead on a more modern and streamlined approach to design. Therefore, Art Deco does not belong to the Georgian century, marking it distinctly as the correct answer in this question.
