De Stijl was an art and design movement founded in the Netherlands in 1917 that sought to express universal concepts through simplification and abstraction using a limited color palette of primary colors, black, white, and grey. Designers formulated a new vocabulary for architecture by deconstructing traditional houses, abstracting them to remove historical references, and reconstructing them with an emphasis on open floor plans defined by relationships between solid and void cubic forms. Furniture and other decorative arts were considered as integral to architecture and interior design, also emphasizing structure, proportion, and balance between solids and voids.
