The Weissenhofsiedlung settlement in Stuttgart, Germany was built in 1927 as a model housing exhibition organized by the German Work Federation under Ludwig Mies van der Rohe. 17 architects constructed 21 buildings with 63 apartments showcasing modern design. Mies van der Rohe designed Houses 1-4 with a flexible floor plan using movable walls. Le Corbusier and Pierre Jeanneret designed Houses 14-15 using Le Corbusier's Five Points of Architecture with a horizontal window and transformable living space divided by sliding partitions. The exhibition demonstrated modern urban housing solutions for different social classes.
