Minor development
Government guidance on flood risk assessments defines a 'minor development' as:
- Minor non-residential extensions: industrial/commercial/leisure etc extensions with a footprint less than 250 square metres.
- Alterations: development that does not increase the size of buildings eg alterations to external appearance.
- Householder development: For example; sheds, garages, games rooms etc within the curtilage of the existing dwelling, in addition to physical extensions to the existing dwelling itself. This definition excludes any proposed development that would create a separate dwelling within the curtilage of the existing dwelling eg subdivision of houses into flats.
