Gropius's complex for the Bauhaus at Dessau has come to be seen as a landmark in modern, functionalist design. Although the design seems strongly unified from above, each element is clearly divided from the next, and on the ground it unfolds a wonderful succession of changing perspectives. The building consists of an asphalt tiled roof, steel framework, and reinforced concrete bricks to reduce noise and protect against the weather. In addition, a glass curtain wall – a feature that would come to be typical of modernist architecture - allows in ample quantities of light. Gropius created three wings that were arranged asymmetrically to connect different workshops and dormitories within the school. The asymmetry expressed the school's functionalist approach and yet retained an elegance that showed how beauty and practicality could be combined.
