The given map shows the Bell Hill form in 1976 and changes that took place over a period of thirty years. It can be seen that the farm was transformed into an environment centre by 2006.
In 1976, there was a farmyard in the centre, which was replaced by a recreational area by 2006. The barn in which corn etc.was stored in 1976 was replaced by a multimedia room in 2006. The storage for farm machinery on the northwest was converted into a car parking area. The farmhouse on the south side was not changed at all. The cow-sheds and poultry area on the east were converted into student housing. The roads on the west were also not altered and remained as they were in 1976.
Therefore, it can be seen that the Bell Hill farm of 1976 underwent a complete transformation and became an environmental centre over a period of three decades.
