Ordnance Survey Maps

For a new conservatory requiring planning permission you will need to supply an accompanying Ordnance Survey based location plan at a scale of 1:1250 and a Site Block Plan at a scale of 1:250. A site plan is also required for Larger Home Extensions under the Neighbourhood Consultation Scheme.

The plan must show your property with the proposed conservatory marked on it to scale and all adjoining buildings and roads, including those at the back and those facing your property.

This process is easier than it once was, as it is now possible to buy a plan of your existing property and the surrounding area from the Planning Portal recommended by Ordnance Survey.
