Blog Post: Permitted Development Extensions in Canterbury: What You Need to Know
At Smith Group, we are often approached by clients who believe their home extension might qualify as permitted development extensions in Canterbury. While the idea of expanding your home without the need for planning permission is undoubtedly appealing, it’s crucial to understand the ins and outs of permitted development rights and how they apply to your project.
In this post, we’ll break down what permitted development extensions in Canterbury really mean, the conditions that need to be met, and how we, as ARB and RIBA registered architects, can guide you through the process to ensure your extension meets the requirements and is fully compliant.
What Are Permitted Development Extensions in Canterbury?
Permitted development extensions allow homeowners to extend their property without the need to apply for full planning permission from the local council, provided certain conditions and limits are met. This government scheme is designed to make it easier for homeowners to improve their properties while alleviating the pressures on local planning departments.
However, permitted development extensions in Canterbury aren’t as straightforward as they may seem. While they do offer more flexibility than traditional planning permission, they come with a specific set of rules regarding the size, scope, and location of the extension, as well as the type of property.
To qualify for permitted development, your extension must meet certain guidelines outlined by the government, such as:
- The extension cannot exceed a specific size (typically around 3 meters for terraced houses and 4 meters for detached properties).
- The extension must not go beyond the rear wall of the house by more than 3 meters for terraced houses or 4 meters for detached homes.
- The extension cannot be higher than the original roofline (except for certain types of rear extensions).
- The materials used must be similar to the existing property.
- The extension must not reduce the amount of natural light that the neighboring properties receive.
- The extension must not cover more than half the land around the original house.
While permitted development extensions in Canterbury do not require planning permission, they do need to meet all the criteria specified in the permitted development rules, which can vary slightly depending on the property type and location.
Why Seek Expert Advice?
While it may sound tempting to bypass the planning permission process, permitted development extensions can be a grey area. The regulations are complex, and many homeowners misunderstand what can and cannot be done under permitted development rights. To ensure your project adheres to these rules, it’s important to consult an expert.
At Smith Group, we are ARB and RIBA registered architects, meaning we are well-versed in the complexities of permitted development extensions in Canterbury. Our team can provide you with sound advice and expert guidance to ensure your extension is both compliant with the regulations and designed to meet your needs.
The Benefits of a Lawful Development Certificate
Once you’ve established that your extension meets the necessary criteria, we always recommend applying for a Lawful Development Certificate (LDC). While not a legal requirement, this certificate provides several key advantages:
- Peace of Mind: The LDC provides official confirmation that your extension complies with the rules and is considered lawful by the local authority. This means you have a solid legal document to show that the work is permitted, which can be important for future sales.
- Confidence for Contractors: Having an LDC ensures that the project is above board, giving contractors confidence in carrying out the work.
- Future Proofing: An LDC can prevent future disputes with neighbors or the local authority over the legitimacy of your extension. It also provides clarity for future buyers if you decide to sell your property.
At Smith Group, we can handle the process of obtaining the Lawful Development Certificate on your behalf, ensuring that all paperwork is completed correctly and submitted to the local planning authority.
