Architecture has the potential to create or transform beauty, symmetry, chaos, and confusion all at the same time. This enormous impact—and the tremendous responsibility that comes with it—requires architects to create structures with a smart blend of daring and humility. It also requires them to understand people's desires, needs, and behaviors in order to design buildings that will be used for a variety of purposes. People love architects because they are able to see beyond the present condition of things to imagine what might be possible in the future. They challenge themselves by trying new ways to solve problems, and their efforts often result in innovative designs that others follow. Finally, people appreciate architects' skills as creators and express their admiration by hiring them when they need help designing their homes or businesses. An architect is someone who sees the invisible parts of buildings and vehicles, which no one else can see. By understanding how things work behind the scenes, an architect is able to design systems that make buildings more efficient at using energy or reducing their impact on the environment. Some famous architects include Frank Lloyd Wright, Louis Sullivan, and Mies van der Rohe. When people hear the word "architect", they usually think about someone who designs big projects like skyscrapers or houses. But an architect also works on smaller projects such as improving lighting system at home or office room.
