The Building Regulations allow some works to be done without an application being required. In most instances it is advisable to contact your local Building Control Department to verify whether or not the work to be undertaken is in fact exempt.
Full details of buildings which are exempt are given in Schedule I of the Building Regulations. The following domestic extensions, subject to a maximum internal floor area of 30m2, are exempt from Building Regulation control and may be constructed without making an application:
- Detached Garages – these must be sited at least 1m from any boundary or be constructed substantially of non-combustible material
- Carports open on at least two sides Porches separated from the dwelling by a door
- Conservatories – these must be separated from the dwelling by an external quality door, have at least three quarters of the area of the roof and half the area of the walls made of light transmitting material and should incorporate safety glazing where appropriate. The floor space should be less than 30m2
Note that Planning Permission may still be required and advice should be sought from Planning Development Control
