Starting in 1944 until ca. 1960, the Finnish government sponsored/published nine different free designs of urban or rural homesteads that could be built by anyone without special tools or skills, "Rintamamiestalo" (Frontline soldier's house). Tens of thousands were built all over the country by veterans and some of the many homeless after the wars (more than one in ten Finns). The construction was either solid log (where timber was available or could be reused from moved or ruined homes) or more common frame houses with walls that were either hollow or most often filled with sawdust as insulation. Simple materials and excellent natural moisture control and heating from the central chimney meant these houses has aged well and remain popular today and in good shape). Rectangular lots were provided by cities and homes were placed close to the street with the long backyards to be used for food gardens and later auxiliary buildings like saunas and wash rooms. Sawdust insulation is safe and clean and easily reused/recycled and the material is cheap and easily available.
