Architecture is present in The Great Gatsby primarily through the homes of the characters. For example, Gatsby's home is frequently referenced, and it is often described as large and elaborate. Additionally, Daisy's home is also described frequently, but because the home is of the older East Egg, it is representative of a more refined taste as well as a more classical style. Other buildings are also mentioned, such as the Plaza Hotel, but are mentioned only briefly.

   Architecture of the 1920s marked the transition from the styles of Art Nouveau to Modernism. Both styles are evident in architecture in the 1920s.
