The provided diagrams illustrate the significant structural changes that occurred at Bell Hill Farm between 1976 and 2006, as it transitioned into an environment centre. Overall, the site shifted from an agricultural focus to an educational facility, with the farmhouse being the only original structure preserved.
In 1976, the farm was primarily dedicated to agricultural activities. The layout included storage for machinery in the top left, a barn for corn in the top middle, and cow sheds located in the top right. A farmyard occupied the central area, with a farmhouse situated in the lower centre and a chicken area positioned to the right of the farmhouse.
By 2006, these agricultural features had been entirely replaced. The storage area was converted into a parking zone, while the barn and cow sheds were replaced by a multimedia room and student housing, respectively. The central farmyard was repurposed into a recreation area. Notably, the farmhouse remained in its original location in the lower centre, serving as the only link to the site's previous identity. The overall layout reflects a shift towards modern institutional use rather than traditional farming.
