The city has several council estates, notably the 1930s estates on the 'arterial road' (Derby outer ring road), 1950s estates such as Mackworth Estate (noted for its London theme in the street names and large green spaces) and more recently some smaller 1970s/1980s estates which are often integrated with private housing.
