The maps show West Park School at three different stages in its changes and development: 1950, 1980 and 2010.
In 1950, the school was built close to a main road and next to a number of houses. A large area behind the school was turned into a playground, while the area behind the houses was farmland.
By 1980, the house had been demolished in order to make way for a small car park and an additional school building, which became the science block. In addition to the existing playground, the school also gained the farmland and converted it into a sports field.
In 2010, the school building remained unchanged but the car park was extended to cover the entire sports field. As a result of this, the original playground was divided into two so that it provided a smaller playground and a small sports field.
During this period, the school increased in size and a car park was created and enlarged. The combined recreational areas, however, first expanded and were then reduced in size.
