The phrase pumpkin architecture is in reference to the revolutionary style of architecture, which later became known as the Hadrianic Style. A further development of the Hadrianic Style is the wide use of circular, elliptical, rectangular, and square shaped patterns. One such example of this unfamiliar style is the implementation of the Doric Pilaster. Another eye-catching detail is the incorporation of caryatids in the structure. The basic format of the Hadrianic Style can be easily defined as a type of jumbo, where you put everything in it and hope it turns out right.
Rooms range from elaborate banquet halls to the hidden underground galleries.
The banquet halls like the Hall of Cubicles, was mainly used for hosting dignitaries for dinner or perhaps used for official meeting areas. Other rooms or areas set aside in the Villa are the famous gardens and courts. The most picturesque of which is the Canopus . The gardens and courts occupy most of the 15,000 acre, perhaps larger area of the Villa. Another space occupied at the Villa was baths.
