The Rietveld Schröder House, a famous 100-year-old modernist masterpiece, was designed in 1924 by the Dutch architect Gerrit Rietveld in collaboration with Truus Schröder-Schräder. This iconic house, located in Utrecht, the Netherlands, embodies the principles of the De Stijl movement, which aimed for a radical reform of art and architecture through abstraction and a limited color scheme of primary colors, black, white, and gray. The Rietveld Schröder House is especially known for its innovative open floor plan and flexible interior walls, allowing for unprecedented freedom in the use of space. The design breaks with traditional architectural conventions by emphasizing horizontal and vertical lines and using functional aesthetics. In 2000, this groundbreaking building was added to the UNESCO World Heritage List, recognizing its significant influence on the development of modern architecture.
