Planning Permission
Rules, known as ‘permitted development’ rights, allow you to extend a house without needing to apply for planning permission if specific limitations and conditions are met.
If you want to exceed these, then it is likely that an application for householder planning permission will be required.
If the work adds over 100 square metres of floor space, it may also be liable for a charge under the Community Infrastructure Levy.
A planning consultant may help with the smooth running of your project. To find an accurate consultancy quote, explore Studio Charrette’s calculators.

- Extensions cannot be higher than the highest part of the existing roof; or higher at the eaves than the existing eaves.
- Where the extension comes within two metres of the boundary* the height at the eaves cannot exceed three metres.
- Extension cannot be built forward of the ‘principal elevation’ or, where it fronts a highway, the ‘side elevation’.
- The work cannot include:
-
- verandas, balconies* or raised platforms.

For side extensions
Where it would extend beyond the ‘side elevation’ of the original house*, the extension:
- Cannot exceed four metres in height.
- Can only be a single storey.
- Can only be up-to half the width of the original house*.
On Article 2(3) designated land* all side extensions will require householder planning permission.
For single storey extensions
- Single-storey rear extensions cannot extend beyond the rear wall of the original house* by more than four metres if a detached house; or more than three metres for any other house.
- Where not on Article 2(3) designated land* or a Site of Special Scientific Interest; and subject to ‘prior approval’, the limit for single-storey rear extensions is increased to eight metres if a detached house; or six metres for any other house.
This requires that the relevant Local Planning Authority is informed of the proposed work via a prior approval application. - Single-storey rear extensions cannot exceed four metres in height.

- Extensions of more than one storey must not extend beyond the rear wall of the original house* by more than three metres or be within seven metres of any boundary* opposite the rear wall of the house.
- Roof pitch must match existing house as far as practicable (note that this also applies to any upper storey built on an existing extension).
- Any upper-floor window located in a ‘side elevation’ must be obscure-glazed; and non-opening (unless the openable part is more than 1.7 metres above the floor).
All side extensions of more than one storey will require householder planning permission.
