Antoni Gaudí introduced several breakthroughs that have significantly impacted our daily lives. His innovative structural designs, epitomised by the iconic Sagrada Família in Barcelona, revolutionised architecture by blending organic and geometric elements. Gaudí's use of novel construction techniques, including the innovative application of catenary arches and hyperbolic paraboloids, pushed the boundaries of engineering possibilities. His incorporation of intricate mosaic work and vibrant stained glass windows created a new aesthetic language. Gaudí's emphasis on integrating buildings with their natural surroundings and his visionary approach to urban planning also influenced contemporary sustainable design practices, fostering harmony between humans, architecture, and the environment.
