In the map transformation of bill hill farm in 1976 to environmental centre in 2006 is illustrated
Generally, during 30 years hill farm completely was modified to a new purpose of utilising the area from farming to modern centre in new century.
Instead of the barn where cons were saved in 1976 there are multimedia room in 2006. Cow and chicken sheds were both on the east of the village but while Cow sheds were replaced with student housing, chicken sheds were destroyed during the forth of the century. Moreover, in 2006 recreation area that is on the centre of the scheme was built in place of farmyard. However, the purpose of the northeast chop that was organised for storage of farm machinery stayed unchanged, but in 2006 there is a parking zone instead. In addition, farmhouse that is located at the bottom of the map and main road stayed the same.
