Key Things to Know About Permitted Development for Single Storey Extensions
Permitted development rights offer homeowners the opportunity to extend their homes without the need for full planning permission. However, specific rules and regulations apply to single storey extensions. Here’s a breakdown of the essential points:
Size Restrictions
- Maximum Ground Coverage: The total area of your extension cannot exceed half the area of land around the original house.
- Height Limits: The extension’s maximum eaves height is generally 3 meters, but this can be increased to 4 meters if it’s more than 2 meters from a boundary.
- Rear Extension Depth: For detached houses, rear extensions can extend up to 8 meters without prior approval. For other property types, this limit is 6 meters.
Boundary and Positional Restrictions
- Boundary Distance: Typically, extensions must be at least 2 meters from a property boundary. However, this can vary depending on the property type and local planning regulations.
- Front Elevation: Extensions cannot be built forward of the principal elevation (front) of a detached house.
Additional Considerations
- Roof Height: The extension’s roof height must not exceed the height of the existing house.
- Materials: The materials used for the extension should match the existing property’s style and appearance.
- Conservation Areas and Listed Buildings: Properties in conservation areas or listed buildings often have stricter regulations, and planning permission might be required.
- Neighbour Consent: While not always necessary, it’s advisable to inform your neighbours about your plans and address any potential concerns.
Note: These are general guidelines, and specific rules can vary depending on your location and property type.
Tips for Designing a Permitted Development Extension
Creating a single-storey extension that not only meets your needs but also harmonises with your property can be a rewarding project. Here are some additional tips to consider:
Maximise Natural Light
- Large windows: Incorporate ample glazing to flood your extension with natural light.
- Skylights: Consider adding skylights for additional light and ventilation.
- Glass doors: Opt for glass doors to create a seamless transition between indoor and outdoor spaces.
Consider Your Lifestyle
- Open-plan living: If you enjoy a sociable atmosphere, consider an open-plan design that connects your extension to the main living area.
- Dedicated space: If you need a quiet workspace or a private retreat, create a separate room within the extension.
- Storage solutions: Incorporate built-in storage to maximise space efficiency.
Enhance Your Outdoor Space
- Bi-fold doors: Create a seamless indoor-outdoor flow with bi-fold doors.
- Patio area: Design a patio or decking area adjacent to the extension for outdoor entertaining.
- Landscaping: Consider incorporating landscaping elements to enhance the overall look of your property.
Prioritise Energy Efficiency
- Insulation: Ensure proper insulation to reduce energy consumption and improve comfort.
- Double glazing: Install energy-efficient double glazing to enhance thermal performance.
- Sustainable materials: Choose eco-friendly materials whenever possible.
Seek Professional Advice
- Architect or designer: Consider consulting with an architect or designer to create a functional and aesthetically pleasing extension.
- Building regulations: Ensure your extension complies with building regulations by seeking professional guidance.
By carefully considering these tips and working within the permitted development guidelines, you can create a single storey extension that adds value and enjoyment to your home.
Additional considerations
In some cases, you may need to apply for planning permission even for a single storey extension. For example, if your property is in a conservation area or if you have a listed building, you will need to get planning permission before you can build an extension.
It is always best to check with your local planning authority to see if there are any specific restrictions in place for your area.
