The parish covers just under in area with 291 houses. The Addington Brook runs through the parish.
Addington can lay claim to be one of the few villages in the country with over 5,000 years of continuous habitation. Addington had two mills at the time of the Domesday survey. There was a watermill powered by the Addington Brook (TQ 656 587 ) which was demolished in the nineteenth century, the site now lies within West Malling Golf Course. The remains of the old Addington Place (now beneath golf course and stables) were visible up until a few years ago, and traces of the former gardens of Addington Park can still be seen. Rockeries, ponds and old tennis courts, are easily discernible in the private grounds of the Seekers Trust between the church and the golf course. It is rich in Neolithic archaeology, but much archaeological evidence has been lost to the mechanical digger. Some sites were excavated during the building of the motorway.
