Maps (or plotting sheets) which are annotated to show all planning applications from 1948 to 2000 are available to view online:
You can view scanned images of the plotting sheets that were held in paper form. Some of these may be difficult to read due to the condition or age of the sheets.
How to navigate the sheets
Enter the address you wish to view in the search field on the map. The address should then appear in the drop down menu of addresses.
Click on the address you wish to view and the map view will then change to show the selected address.
Click on the map in the area you are interested in and you will then see a list of the relevant plotting sheets (named Map 1, Map 2, etc.)
Select a map to view from the list.
