The story
Riksbyggen was founded in 1940, by trade unions in the construction sector as a response to the current housing crisis and unemployment among construction workers. Among those founders were Viktor Björkman, Ture Blomqvist, Ed Kärrfeldt, Nils Linde and Anders Nilsson. In 1952, the company Byggfackens Central AB was formed with the task of responding to Riksbyggen's asset management. Riksbyggen had by 1974 built 200,000 dwelling units, 55 percent of them cooperatives; HSB had built somewhat more, and these two big institutions managed about two-thirds of half-million cooperative housing units in the country.
