This zone is found within Sheffield and Doncaster where early municipal housing developments have been considered separately to those established in the late 20th century. This differs to the zones in the rest of South Yorkshire. This difference is primarily because of the larger numbers of municipal suburbs built on the edges of Sheffield and the clear differences between the early and later developments in Sheffield and Doncaster.  Housing within this zone tends to be built in radial patterns with semi detached properties or short row terraces, patterns that have much in common with the planned industrial settlements found across the county.  There are also many similarities with contemporary private housing developments.
