Deleted in line with whose "policy"?

The OSMUK Cadastral Parcels layer suggests that it belongs to Ashlar Court, so I have undeleted it and tagged it as access=private + private=residents

If the car park is shared with East Finchley Baptist Church, it and the access roads would need be tagged with access=customers
