The document discusses two architectural styles: Googie's and Brutalism, detailing their origins, characteristics, key architects, and notable examples. Googie's architecture, popular from the 1940s to the early 1970s in the U.S., featured vibrant, space-age designs with curvilinear forms and bright colors. Brutalism, emerging in the 1950s as a response to post-war reconstruction, is characterized by raw concrete materials, minimalist construction, and angular geometric shapes, but saw a decline in popularity by the late 1970s.
