Sunila pulp mill and residential area (1936–38, 1947, 1951–54) form the largest entity realized according to Alvar Aalto’s original plans. Aalto drew up a master plan for the industrial community in summer 1936. He separated the factory from the residental area by placing the former on a rocky island accessible via an embankment, and scattered the residential units on the mainland, thus creating Finland´s first “forest town”. The scheme is still a harmonious example of the socially driven construction of the period and of the possibilities and achievements of building technology.
