The diagrams illustrate the changes that took place between 1936 and 2007 in a town called Harborne.
Overall, the town underwent a number of dramatic changes, the most important of which are the development of a residential area and the replacement by museum and golf course catering for the increase in the recreational needs.
While many trees were cut in the north-west, the bicycle track was removed to make way for the road in the south-west. In the center of the Harborne town, no changes were made to the post office, bank and library during seventy-one years. The candy store and butchers in the northern part next to the post office were combined to become a new supermarket for purchasing purposes, and there used to be an empty plot of land in the center part in 1936, but it was then built as a shopping centre in the next seventy-one years. The flower shop under the shopping centre and next to the bank was constructed in 1936, which was replaced by a travel agent in 2007.
In the north-east, there used to be a river in 1936, but it was then redeveloped as a residential area for the following seventy-one years. The town of Haborne also saw a number of changes, with the government office being turned into a museum, and the farmland being converted into a golf course.
