The diagram delineates the evolution of Bell Hill Farm from a farming establishment in 1976 to the establishment of Bill Hill Environmental Centre in 2006. Over the course of three decades, a substantial metamorphosis has occurred, transitioning the site from agricultural use to an educational facility.

Consequently

, various areas previously devoted to farming activities have undergone renovation and modernization to cater to the educational needs of the institution. In 1976, the storage facility housing farm equipment

such

as tractors and machinery was repurposed into a parking lot by 2006. Simultaneously, on the opposite side, where once stood a barn for housing cows and chickens, a new residential complex was erected to serve the academic community.

Furthermore

, the barn area previously utilized for cultivating crops like corn underwent a transformation into a state-of-the-art multimedia facility.

Moreover

, the central farmyard was excavated and transformed into a recreational area. Despite these extensive modifications, the sole unchanged feature throughout the transition was the farmhouse situated at the heart of the premises.
