The maps elucidate the diversions that were brought in the years 1976 and 2006, to the Bell Hill Farm which was converted to an Environment Centre.
Overall, there were some drastic changes as the purpose of a farm and that of an environment centre are totally different.
In 1976, known as Bell Hill Farm, most of the properties were related to farming. The farm contained storage for farm machinery, barn for corn and other crops and shed for cows. There was a farmhouse on the middle. There was a road in one side of the farmhouse and on the other side, there was space for chicken. The space between the farmhouse and the barn was used as farmyard.
In 2006, while the name was converted to Environment Centre, most of the properties were replaced except the farmhouse and the road beside it. The farmyard was changed to recreational area, the barn was replaced with multimedia room and the storage for farming machineries was used for parking. There was a student housing in the rightmost part which previously had a shed for cows and space for chicken.
