Contemporary architecture is the architecture of the 21st century. It aims to break away from standard processes and thinking and is innovative. No single style is dominant, as contemporary architects work in postmodern, high-tech, and expressive styles. It features curved lines, composite volumes, new materials like glass and plants, large windows, and environmental considerations. Famous examples include Walt Disney Concert Hall with billowing stainless steel, Galaxy Soho with connected spherical structures, and Congregation Beth Sholom with an imposing pyramidal roof.
