This lecture introduces Frank Lloyd Wright as one of the most influential architects of the modern era and explains his role as a pioneer of organic architecture. It covers Wright’s life, early training, and the wide range of buildings he designed, including Prairie Houses, Usonian houses, concrete block houses, and organic works. The lecture explains key ideas such as “breaking the box,” free-flowing interior spaces, horizontal proportions, low-pitched roofs, and strong connections with nature, which defined Wright’s Prairie House concept. Through important projects like Winslow House, Robie House, Ward Willits House, Unity Temple, and Fallingwater, the lecture shows how Wright transformed domestic architecture by integrating structure, space, materials, light, furniture, and the site into a unified whole. The session also highlights Wright’s influences, especially Japanese architecture, and sets the foundation for understanding his lasting impact on modern architecture.
