Frank Lloyd Wright was an influential American architect known for pioneering organic architecture that aimed to harmonize structures with their natural surroundings. One of his most famous works is Fallingwater, a house built in 1937 near Mill Run, Pennsylvania. Fallingwater is built directly over a 30-foot waterfall, with terraces that echo the rock ledges below. Wright designed the house so that its residents could experience the waterfall as part of their daily life, with water sounds heard throughout. The home exemplifies Wright's organic style through its integration with the surrounding forest and use of local materials like stone.
