This style consciously copied the past for ornamental details. An example of such are the battlements parapet at the top of the building. There are many original features of this building that survive - this is a Listed Building so they are now protected. Some alterations to Dobson's work have taken place. A garden wall was added in 1904 by the nationally-famous Edwin Lutyens. Some of the changes can be seen in the various editions of the Ordnance Survey mapping of the area.
