Modernist architecture SOK has a key position in the history of Finnish architecture due to its policy in the late 1920s and 1930s of designing cutting-edge Modernist architecture, epitomized by a Functionalist aesthetic of white buildings. The key architect designing for SOK in the initial years was Erkki Huttunen (1901–1956), who designed various types of buildings for the company: from grain silos and mills to local village shops. Among his best-known works for SOK are the Toppila mill (1929, pictured right), the SOK Offices and Warehouse (1937-38) in Oulu, the SOK Offices and Warehouse (1931) in Rauma, and the Aitta Cooperative Shop (1933) in Sauvo. Today, many of these buildings are protected by law.
