The maps provided illustrate what changes took place in Bell Hill Farm in 1976 and in 2006 when its name was altered to Bell Hill Environmental Centre.
Overall, almost all of the parts except Farmhouse were changed to modernize the place.
There was a stream flowing in the southwestern part of the area, and a storage for keeping machinery needed for the farm was located above in the Northwest in 1976. Neverthless, it was turned to parking for vehicles after 30 years. Barns like corn were cultivated in the field beside the storage in the North in 1976 before it was abolished to construct a room for multimedia in 2006. A farmyard was situated in the middle of the Farm in the initial year of the period; however, it was changed to an area special for recreation after 30 years passed. Moreover, the cow sheds available in the eastern side in 1976 were demolished to build a housing for students in 2006.
The only part of Bell Hill Farm that remained unchanged in both years was Farmhouse placed in the South next to the stream.
