The provided map illustrates how Bell Hill Farm revolutionized the Environment center over 3 decades (from 1976 to 2006).
Overall, it can be clearly seen that radical transformation occurred in the farm, however not all spots were totally changed.
On the whole, in 2006, a multimedia room, in the upper middle, replaced the barn which contained corn and other grains in 1976. Moreover, the farmyard was demolished, and in its place, a recreation area was constructed. Towards the right side, an area for chickens and cow sheds observed a considerable renovation, transferring into student housing. Finally, it is possible to observe that the warehouse for agriculture, at the upper left corner of the map, was converted into a vehicle parking space.
Probing further, it is evident that the farmhouse in the bottom and the road, located on the left from it, did not experience any changes throughout the whole period.
