A single-story extension can be a fantastic way to add valuable space to your home. However, understanding whether you need planning permission is crucial. Let’s explore the factors that determine whether your extension falls under permitted development or requires a full planning application.

Permitted Development for Single-Story Extensions
In general, single-story rear extensions are considered permitted development, allowing homeowners to build without formal planning permission. However, there are specific conditions that must be met:

Size Restrictions: The extension cannot exceed a certain size, which varies depending on your property type and location.
Height Restrictions: The extension must not exceed the height of the existing house.
Materials: Certain materials, such as brick or timber, are typically permitted.
Location Restrictions: Extensions must be located within a specific distance from the property boundary.
When Planning Permission is Required
If your extension doesn’t meet the criteria for permitted development, you’ll need to apply for full planning permission. This might be necessary if:

You exceed the size or height restrictions.
Your property is in a conservation area or listed building.
You plan to add features like balconies or verandas.
Your local planning authority has introduced Article 4 directions.
Factors Affecting Permitted Development
Property Type: The type of property (detached, semi-detached, etc.) can affect the permitted development rights.
Location: Properties in certain areas, such as conservation areas or areas of outstanding natural beauty, may have stricter regulations.
Local Planning Policies: Your local planning authority may have additional rules or restrictions.
Seeking Professional Advice
If you’re unsure whether your single-story extension qualifies for permitted development, it’s advisable to consult with a professional, such as an architect or planning consultant. They can assess your specific circumstances and provide guidance on the best course of action.

By understanding the rules and seeking expert advice, you can navigate the planning process efficiently and maximize the potential of your home extension.
