Contemporary buildings are structures designed in the late 20th century to the present, characterized by innovative designs and the use of modern materials. They often feature open spaces, large windows, and a blend of functionality and aesthetics. Architects like Zaha Hadid and Frank Gehry are known for their unique approaches that challenge traditional architectural norms. These buildings often incorporate sustainable practices, such as energy-efficient systems and eco-friendly materials. The focus is on creating spaces that are not only visually appealing but also environmentally responsible. Examples include green roofs and solar panels, which enhance the building's efficiency and reduce its carbon footprint.
