Norman Foster is a renowned British architect known for high-tech and sustainable architecture. Some of his most famous buildings include London City Hall, 30 St Mary Axe (known as the Gherkin), and the Reichstag building in Berlin. For London City Hall, Foster designed a uniquely bulbous shape to reduce energy needs by decreasing surface area. 30 St Mary Axe's distinctive cigar shape maximizes airflow and minimizes wind impact. For the Reichstag, Foster sensitively restored the historic structure and added a transparent dome symbolizing democracy. Across all projects, Foster aims to fulfill functional needs while creating aesthetically pleasing landmarks through innovative design.
