Later in the 1920s, Migge's designs moved from individual productive garden plots (based on the "Kleingarten" and "Schrebergarten" model) to the Kolonial Parks, grouping smaller plots around a communal park area. In his 1926 book "Die Deutsche Binnen-Kolonisation" (German Inland-Colonization), Migge described gardens as industrial products that were essentially tools for better living. He viewed the garden not as a bourgeois escape from industrialized society but rather as a mechanized object, a compatible means of improving life in a mechanized society. The notion of colonization from within was also a criticism of Wilhelmine Germany's imperialist ambitions. Although Migge saw the virtue in resettlement outside the city as a means of connecting back to the land, his ideas for organizing space applied to the urban inhabitant, the overriding concepts being a part of a comprehensive urban regional planning.
