6.1.1
A BLPU is defined in BS 7666-2:2006 as a real world Object which is an ‘area of land, property or structure of fixed location having uniform occupation, ownership or function’. The BLPU is the core element of the data and is the Object to which Records are linked via reference to the Unique Property Reference Number (UPRN). In essence a BLPU associates a real world Object on the ground to a UPRN.
6.1.2
If a site contains more than one BLPU and there is a textual relationship between the LPI Records, for example a hospital, then a Parent BLPU should be created for the whole site and Child Records should be created for the BLPUs within the site.
6.1.3
Each BLPU Classification is based on a number of existing Classification schemes currently in use within England and Wales in both the public and private sectors. Care has been taken to facilitate compatibility with the:
- Valuation Office Agency (VOA) property Classifications, Non-domestic Rates, Rating Manual, 2014.
- Royal Institution of Chartered Surveyors (RICS), Planning Use Class Order, Land Use Gazetteer, 3rd Edition Volume 1, printed 2005, published by Leaf Coppin.
- National Land Use Database (NLUD), Land Use and Land Cover Classification, Version 4.4, February 2006.
- Building Regulations 2000, Volume 2, Part B of the 2006 edition.
- Fire Service Emergency Cover (FSEC) toolkit, Building Classifications, DCLG, circa 2012.
and the Classification codes identified in Appendix C although all are not necessarily given the same weighting. For a table of the relationship between these codes, see Appendix D.
