Understanding Planning Permission for Decking
First, let's define what we mean by 'decking'. In the context of UK home improvement, decking refers to a flat platform usually extending from the house into the garden. It's a popular feature in many UK homes, providing a versatile outdoor living space. When planning your decking project, it's crucial to consider decking and planning permission to ensure you comply with local regulations.
Why Is Planning Permission for Decking Important?
Decking planning permission is a legal requirement in the UK for certain types of developments. It's a way for local authorities to control the development of land and buildings. This ensures that any development aligns with the local planning policy and doesn't negatively impact the local community or environment.
Here are some key points to understand about planning permission for decking:
It's not always required. Whether you need it depends on various factors, such as the size and location of the decking.
If required and not obtained, you could face enforcement action. This could mean having to remove the decking and pay a fine.
Even if planning permission isn't required, you may still need to comply with decking building regulations. These are separate from planning permission and ensure the safety and quality of the construction.
Understanding these points is the first step towards a successful decking project.
Do You Need Planning Permission for Decking in England?
The answer to this question largely depends on the specifics of your decking project. In England and the rest of the UK, certain criteria and decking regulations must be met to determine whether planning permission is required.
Generally, if your decking meets the following conditions, you likely won't need planning permission:
Height: The decking is not raised more than 300mm (30cm) above ground level.
Size: The decking covers less than 50% of the total garden area.
Location: The decking is not situated forward of the principal elevation of the house that faces onto a road.
Conservation Areas or Listed Buildings: If your property is part of a listed building or is located in a designated conservation area, you may face extra restrictions and need to obtain planning permission.
If your decking project falls outside of these parameters, it's advisable to consult with your local planning authority to confirm whether planning permission for decking is required.
Specific Scenarios Requiring Planning Permission for Decking
Raised Decking Planning Permission
Raised decking, which is decking that has been elevated above the normal ground level, almost always requires planning permission due to potential impacts on privacy and overshadowing neighbouring properties.
Planning Permission for Decking on Sloping Ground
If your garden is on a slope, creating a level decking platform may necessitate support structures that elevate parts of the decking. This situation usually requires planning permission for decking because it changes the natural ground level and could impact neighbours.
By considering these factors and regulations, you can ensure your decking project complies with local laws and enhances your property without causing issues.
Where is Decking Height Measured From?
Decking height is generally measured from the ground to the top surface of the decking boards. This measurement is crucial for determining the elevation of the deck above the surrounding area and ensures proper installation and alignment with existing structures or entry points.
Remember, planning permission for decking over 30cm in height will be required and needs to be applied for and approved before the project begins.
Decking and Permitted Development Rights
Permitted Development Rights play a crucial role in decking projects, enabling specific types of work to proceed without the need for planning permission.
Decking falls under the category of "outbuildings and other additions". This means Permitted Development Rights often cover it. However, there are still size and height limits to consider.
It’s important to keep in mind that Permitted Development Rights are subject to local planning regulations. Therefore, to avoid a fine, it is always worth checking with your local planning authority about whether you need planning permission for decking so they can confirm whether your project falls within these rights.
Decking in Special Areas: Conservation and Listed Buildings
Obtaining planning permission for decking in conservation areas or listed buildings can be a complex issue. These areas have strict rules to preserve their historic or natural value. If your property is in a conservation area or is a listed building, you may need to apply for planning permission. This is regardless of the size or location of your decking.
Always consult with your local planning authority before starting your project. They can provide guidance on the specific regulations for your area. Remember, it's better to be safe than sorry when it comes to preserving our heritage.
Applying for Planning Permission for Decking: Steps and Documents
Applying for planning permission for decking in the UK involves several steps. Following these steps is crucial to ensure your decking planning application is successful. First, you need to prepare a detailed plan of your proposed decking. This should include accurate measurements and clearly depict its location on your property.
Next, you need to fill out the necessary application forms. These can usually be found on your local council's website. Here is a general list of documents you might need:
A completed application form
The location plan of your property
A site plan showing the proposed decking
Any necessary supporting documents
Finally, submit your application to your local planning authority. They will review your application and make a decision. This process can take up to eight weeks, so plan accordingly.
Planning Permission for Decking: Common Pitfalls
When planning for decking, it's essential to avoid common pitfalls. One common mistake is not considering the impact of your decking on your neighbours. Decking can sometimes lead to issues with privacy. It's important to consider the height and location of your decking to avoid overlooking your neighbours' properties.
Another issue is not considering drainage. Proper drainage is crucial to prevent waterlogging and damage to your decking. Lastly, always remember to check with your local council before starting your project. This can save you from potential legal issues and fines.
While the need for planning permission for decking in the UK can seem daunting, understanding the regulations and seeking guidance from your local planning authority can help streamline the process. By adhering to the necessary guidelines and obtaining any required permissions, you can enjoy your decking, knowing it complies with regulations and responsibly enhances your outdoor living space.
