Toronto's older buildings are influenced by the city's history and culture. Most of the city's older buildings adopted designs found in other areas of the British Empire, such as Georgian, Victorian, Edwardian, and various revival-styled designs that were popular during the 19th and early 20th century. In the years following World War II, the city experienced massive growth and adopted a number of modernist and postmodernist architectural styles, including the International Style and the towers in the park concept. With adoption of the Greenbelt throughout the Greater Toronto Area in 2005, the region has experienced a large condo boom with many designs adopting neomodern styles. Since the end of World War II, many prominent architects have done work in city, including Toronto native Frank Gehry, Daniel Libeskind, Norman Foster, Will Alsop, I. M. Pei, and Ludwig Mies van der Rohe. Reflecting this eclectic combination of architecture, Lawrence Richards, a member of the Faculty of Architecture at the University of Toronto, has said "Toronto is a new, brash, rag-tag place—a big mix of periods and styles."
