4.3.2.1
The SNN Authority must number all new property developments regardless of development type. The exception to this rule is if new properties require names or numbers on an existing Street Name where no numbering exists. The SNN Authority should consider creating a numbering scheme if it causes no problems for existing property owners.
4.3.2.2
Street Names should be numbered so that when travelling away from the centre of a town odd numbers are on the left hand side and even numbers on the right unless an established local convention is different.
4.3.2.3
Street Names should be numbered ascending from the most important Street from which they lead.
4.3.2.4
Infill development on an existing numbered Street Name should include any required suffix to property numbers if no consecutive number is available in the current numbering scheme or if more numbers are required than numbers are available. The SNN Authority should also consider creating an additional Street Name.
4.3.2.5
In certain cases it is more appropriate to number properties sequentially, for example cul-de-sacs.
4.3.2.6
Merged properties must adopt a previous Addressable Object as their identifier if property numbers are used. Therefore, the merging of two properties at “4 High Street” and “6 High Street” results in a new Record which includes the number “4” or “6”. For example the new Addressable Object Record is “4 High Street”, “6 High Street” or “4 to 6 High Street”. Previous Addressable Object Records for “4” and “6 High Street” should be flagged as historical Records within the LLPG. Similarly, the merging of three properties at “2”, “4” and “6 High Street” result in a new Addressable Object Record which includes the number “2” or “4” or “6”.
4.3.2.7
Sub-divisions of property should always be numbered rather than described or lettered therefore “Flat 1” should be used rather than “First Floor Flat” or “Flat A”.
4.3.2.8
Conversion of a house to flats with a common entrance should result in the creation of Child Records referenced to a Parent property rather than the creation of suffixed numbers, for example, “Flat 1 36” not “36A”.
4.3.2.9
All properties must be numbered and / or named onto the Street Name which provides direct access to the property, which is generally the Street that the front door of the property faces. All other accesses must be retained as recognised Alternative LPI Records for the property, associated with the same UPRN.
