However, let’s explore whether you need permission for your single-storey extension.

 

Understanding Planning Permission

Planning permission is a key factor to consider before you start building. It determines whether you can proceed with your extension without the risk of legal complications. The good news is that many single-storey extensions do not require planning permission, as they are classified under Permitted Development.

Permitted Development Rights

Permitted Development Rights allow you to make specific changes to a building without applying for planning permission. However, these rights are subject to conditions and limitations designed to control impact and preserve the character of local areas.

For a single-storey rear extension to fall under standard Permitted Development, it must generally:

1. Extend no more than three metres beyond the original rear wall of an attached house, or four metres for a detached house.

2. Not exceed four metres in overall height.

3. If it is within 2 metres of a boundary, the eaves height must not exceed 3 metres.

4. Not cover more than half of the garden area.

5. Use materials similar in appearance to the existing house.

Larger Home Extension Scheme (6m / 8m Extensions)

In addition to the above, homeowners in England may be able to build a larger single-storey extension without full planning permission:

• Up to 6 metres beyond the original rear wall of a semi-detached or terraced house

• Up to 8 metres beyond the original rear wall of a detached house

To do this, you must apply for Prior Approval through the Neighbour Consultation Scheme. This is not full planning permission, but the council will notify your neighbours and consider their feedback before granting approval. This scheme is now permanent and widely used across many local authorities.

Article 4 Directions and Listed Buildings

Local councils may introduce Article 4 directions in certain areas, particularly conservation areas, to remove or restrict Permitted Development rights. In such cases, even small extensions may require planning permission. Additionally, if your property is a listed building, you will need both planning permission and listed building consent for any extension work.

Building Regulations Approval

Regardless of whether planning permission is required, Building Regulations approval is always necessary. This ensures your extension meets structural, energy efficiency, ventilation, drainage, and fire safety standards. Building Regulations approval is a separate process from planning permission.
