The homeowners guide to two-storey extensions.
Two-storey extensions provide an excellent opportunity for homeowners in the UK to significantly increase their living space and enhance the functionality of their homes. Whether you need more bedrooms, a larger living area, or a combination of both, a two-storey extension can transform your property. However, understanding the planning and building regulations is crucial to ensure a smooth and compliant process.
Do I need planning permission for my two-storey extension?
Planning and building regulations for two-storey extensions are more stringent than for single-storey ones.
Here’s an overview:
Planning Permission: Two-storey extensions generally require planning permission. You will need to submit a detailed application to your local council, including plans and designs. The council will consider factors such as the extension's size, impact on neighbors, and adherence to local planning policies.
Permitted Development Rights: In some cases, two-storey extensions may fall under permitted development rights, but they must meet strict criteria. These include limits on height (no higher than the highest part of the existing roof), distance from boundaries (at least seven meters from the rear boundary, 2m for the sides), and overall size.
Building Regulations: Compliance with building regulations is mandatory for all two-storey extensions. These regulations cover structural integrity, fire safety, energy efficiency, sound insulation, and accessibility. A building control surveyor will inspect the work at various stages to ensure compliance.
Party Wall Act: If your extension involves work on a shared wall or boundary with a neighbour, you must comply with the Party Wall Act, which involves notifying and obtaining agreement from affected neighbour’s.
Heritage and Conservation Areas: If your property is listed or located in a conservation area, additional consents such as listed building consent or conservation area consent may be required. These areas have stricter rules to preserve their historical and architectural significance.

Benefits:
Significant Increase in Property Value: A well-executed two-storey extension can substantially increase the market value of your home, making it a smart investment.
