The newest contribution to Bucharest's architecture took place after the fall of Communism, particularly after 2000, when the city went through a period of urban renewaland architectural revitalizationon the back of Romania's economic growth. Buildings from this time are mostly made of glass and steel, and often have more than 10 stories. Examples include shopping malls (particularly the Bucharest Mall, a conversion and extension of an abandoned building), office buildings, bank headquarters, etc.
