American architect William Pereira is known for his futuristic designs. At the time of his death, the architect had over 400 projects to his name. However, Pereira is no stranger to criticism. One of Pereira's most unconventional buildings is the Geisel Library at San Diego University in California. The brutalist building evokes a space-age feel and challenges its surroundings with its intensity. It even made Reuters' list of "Top 10 Ugly Buildings to Visit."
