Double House 

"Double House" is a schematic drawing by Dutch artist Theo van Doesburg. It is a floor plan of a two-story house, with two symmetrical halves separated by a central staircase. Van Doesburg, a leading figure of the De Stijl movement, was known for his use of geometric forms and primary colors in his art, and this architectural design reflects those principles. The drawing is a testament to the artist's interest in functionalism, and the clean lines and simple design reflect the ideals of the De Stijl movement. De Stijl, or "The Style," was a Dutch artistic and architectural movement of the early 20th century that emphasized geometric abstraction, simplicity, and functionality.
