    • The glazing complies with Part N of the Regulations (i.e. Protection against impact)
    • They are single storey
    • They are built at ground level
  • Carports are exempt from the Regulations provided that they have a floor area less than 30m2 and are open on at least two sides

    • They are a detached single storey building with a floor area of less than 30m2
    • They contain no sleeping accommodation
    • No point of the building is closer than 1 metre to the boundary or its curtilage (the ground adjacent to a building and associated with its use, normally in the same ownership as the building) OR
    • The building is constructed substantially of non-combustible material
  • Detached buildings not normally used by people e.g. Buildings containing fixed plant or machinery intermittently used by people only for purposes of maintenance or inspection
