Even if officials deny a direct ban on buying one’s own home, politicians from the Greens have repeatedly commented on this. In February last year, for example, the then parliamentary group leader Anton Hofreither was only hesitant to deny that “the Greens want to ban their own four walls”. The interview with the Green Hamburg District Councilor Werner Boelz caused a particular uproar. This decreed a construction freeze for single-family houses in the city area. Chris Kühn, former construction and housing policy spokesman for the Greens parliamentary group, said: “The time of single-family houses in new construction is over.”
