the buildings at , carried out in the summer of 2012, identified a small maternity colony of brown long‐eared bats (Plecotus auritus) roosting within the enclosed roof void in the north wing of the house and a single brown long‐eared bat utilising the east wing of the house as a day roost for a very short period of time. In addition, a barbastelle bat (Barbastella barbastellus) and a brown long‐eared bat were utilising the open roof void of the adjacent barn as a night roost. Planning consent is being sought from Cherwell District Council to renovate the at , carry out repairs to the front and then convert the adjoining barn into residential accommodation with an open ceiling. In addition, there are plans to construct a double garage, swimming pool/pool buildings and a garden
