Today many of Frank Lloyd Wright’s architectural concepts and principles are everywhere, so embedded in the cultural canon they’re easily taken for granted. Wright’s early Prairie-style houses disowned their boxy antecedents to recall the prairie landscape of the Midwest. His buildings grew from the characteristics of the site, the materials he found locally, and his perception of the shapes that would serve the needs of his clients while complementing their surroundings. Over seven decades, from his first structure to his last, Wright was continually innovating. Relevant historical information accompanies each image.
