In both these districts the ideals of Functionalist architecture — multi-family buildings in a natural scenery — were therefore implemented.
A plan for the area was adopted in 1930, featuring 15 metres thick buildings 3–4 stories tall.
The early 1930s saw few construction projects realized, and when a builder willing to carry the project out finally appeared, he demanded that the plan should be redrawn in accordance to a proposal by Ragnar Östberg — a plan featuring buildings 10 m wide arranged in an unmistakably classicist manner.
Construction finally started in 1935, but, due to the stalled negotiations, Hammarbyhöjden lost its pioneering role to Traneberg which had its 1932 city plan quickly realised.
On its completion, the district was described as an "ideal society" and named "The White city" (Den vita staden), but its first inhabitants were more sceptical, complaining on inadequate services, high rents, and the long distance to the city centre.
