The Oulton conservation area was first designated in 1975. In 1987 it was extended to include Oulton Hall and park. There are a number of listed buildings in the area, such as the iconic Nookin which is believed to have been built in the 1600's.
Living within the conservation area puts some responsibility on residents. Changes to the appearance of buildings and things such as tree pruning or removal are more regulated than they are outside of the conservation area. It is always best to check the guidelines before commencing any work.
