Colville Hall is a significant group of historic buildings dating back to the 13th century. To inform a planning application GreenLink Ecology Ltd. was instructed to undertake a variety of surveys for the site in 2011 and subsequently a European Protected Species licence for bats was successfully applied for in 2012. The buildings have now been renovated and the population of bats is confirmed to be still present due to the implementation of careful mitigation and enhancement measures.
