The National Planning Policy Framework (NPPF) Annex 2: Glossary, published by the Ministry of Housing, Communities & Local Government (MHCLG) in 2012, defines a major development as: ‘For housing, development where 10 or more homes will be provided, or the site has an area of 0.5 hectares or more. For non-residential development it means additional floorspace of 1,000m2 or more, or a site of 1 hectare or more, or as otherwise provided in the Town and Country Planning (Development Management Procedure) (England) Order 2015.’ (Other than for the specific purposes of paragraphs 172 and 173 in the Framework).
- ‘For dwellings: where 10 or more are to be constructed (or if number not given, area is more than 0.5 hectares).
- ‘For all other uses: where the floor space will be 1000 sq metres or more (or the site area is 1 hectare or more). The site area is that directly involved in some aspect of the development. Floor space is defined as the sum of floor area within the building measured externally to the external wall faces at each level. Basement car parks, rooftop plant rooms, caretakers’ flats etc. should be included in the floor space figure.’
