11.8.4.1
This section provides guidance on dealing with conversions and internal numbering that should be advised through the SNN processes within an SNN Authority. If a premises number exists it must be used at all times in each new Addressable Object to facilitate the differentiation of all units and sub-units of the property.
11.8.4.2
If the property being converted is named then this name must endure throughout all newly created subdivisions of this property. If the property only has a name then the SNN Officer should use the change of Addressable Object as grounds for officially allocating an SNN Authority number to the property, as well as its name.
11.8.4.3
Conversion of a house into two or more residential flats with one door providing access to all flats:
- The Parent building shell shall be recorded as a PAO with the property number (and name where applicable) and Child BLPUs created as SAOs each numbered as Flat 1, Flat 2 and so on, for example; “Flat 1”, “29 Wigan Road”, “Pemberton”.
- Parent BLPU Classification must be recorded as BLPU_CLASS = “PP” (property shell).
- If a location description for the flat exists such as ground floor these details should be entered into the level Field.
11.8.4.4
Conversion of a house into two or more residential flats with separate external doors providing access to each of the flats.
11.8.4.5
PAOs for all flats must be created with Addressable Objects suffixed to the property number of the existing property, for example; “29A”, “Wigan Road”, “Pemberton” and “29B”, “Wigan Road”, “Pemberton”.
11.8.4.6
If one door provides access to more than one flat then see Section 11.8.4.3 above, for example; “Flat 1”, “29A”, “Wigan Road”, “Pemberton”.
11.8.4.7
If a single building contains flats and / or shops with single or multiple access doors to each or all flats:
- The building shell shall be created as a PAO with the building name and / or number as the Addressable Object.
- Child BLPUs shall be created for each flat / shop with the SAO as “1”, “2”, “3”, “4” etc.
- To avoid confusion, numbers should be subdivided into suffixed properties or prefixed with the words “Office”, “Unit”, “Suite”, “Apartment” or “Flat”. If location descriptions exist for these properties these should be entered into the level Field. See Figure 15. For further information on the level Field see Section 7.4.4.1.
