Certain types of building work are classed as exempt and don’t need building regulations approval. However, they may need planning permission. Here are some common examples:
- Buildings not used by people
- Caravans or mobile homes
- Greenhouses and agricultural buildings (unless used for retail etc)
- Temporary buildings – not intended to remain more than 28 days
- Ancillary buildings – such a building site office
- Small detached buildings
- Having a floor area which is not more than 30m2, which contains no sleeping accommodation, and is a building
(a) No point of which is less than one metre from the boundary of its curtilage; or
(b) Which is constructed substantially of con-combustible materials. (The exemption applies to combustible materials if the floor areas of the building are no greater than 15m2)
- Extensions – the extension of a building, (less than 30m2 floor area) by the addition at ground level of:
(a) a conservatory (see note below), porch, covered yard or covered way; or
(b) a carport that opens on at least two sides.
Please note: An extension must be substantially glazed before it can be termed a conservatory. If heated, it must have a separately controlled heating system, safety glazing and must be separated from the house by external quality walls, windows and doors.
