This zone is found extensively in the city of Sheffield. It is also concentrated around the principal urban centres of Doncaster, Barnsley, Rotherham and Mexborough. The rate that many of these areas of housing were built shows the rapid housing requirements for the growing industrial populations of South Yorkshire. Terraced housing was being built before the establishment of many of these terraced grids in the mid 19th and early 20th century but generally not on the large scales of these areas or in such established grid patterns. Houses are often very uniform due to the development of bylaws that controlled housing size. Houses often still have outside toilets which were either accessed by a back lane running along the rear of the housing or through alleyways running through the terrace at intervals.
