If you’re considering adding to your home, one of the first questions that might cross your mind is do you need planning permission for a conservatory?
Let’s take a look into the details and break down the process so you have a better understanding.
What is planning permission?
Before looking at the specifics of planning for conservatories, it is important to clarify what planning permission is and is not.
In the UK, planning permission is essentially official consent from your local authority to proceed with certain types of building work or changes to the use of buildings. Planning permission focuses on ensuring that any proposed changes to your house comply with local planning policies.
When you’re thinking about making your home bigger, there are some rules called permitted development rights. These rules let you add extra space to your original house without having to get special permission, but you have to follow certain limits and conditions. A single storey extension is often simpler to get approved, however projects that involve more than a single storey will likely require full planning permission. Whether you’re planning a single storey rear extension or considering more than one storey, understanding the rules is crucial for a smooth process.
If you want to go beyond these limits, especially if your extension is more than 100 square metres, you’ll probably need to ask for householder planning permission. Keep in mind that larger projects might also come with a charge called the Community Infrastructure Levy.
If this sounds confusing, don’t worry! It’s a good idea to contact your Local Planning Authority before you start any work. They can give you advice on conservatory planning permission on semi detached homes and detached houses alike, and help you understand what you can and can’t do. It’s better to check first to avoid any issues with your planning application later on.
Do you need planning permission for a conservatory?
The good news for many homeowners is that, in most cases, the answer is no, you won’t need planning permission for a conservatory. Permitted development rights often cover conservatory installations. However, there are conditions and limits, so it’s important to be aware of these.
Permitted development rights allow certain types of building work without the need for formal planning permission, providing a streamlined process for specific projects.
When do you need planning permission for a conservatory?
When your conservatory falls outside of permitted development rights, you may need to obtain conservatory planning permission. Let’s look at the conditions.
Permitted development conditions
The new conservatory should not exceed 50% of the total area of land around the original house. It should not project forward of the principal or side elevation of the original house. Also, the maximum height of the conservatory should not exceed the highest part of the existing property’s roof.
Size and location
The size and location of the conservatory play a crucial role. Generally, smaller conservatories that meet specified criteria are more likely to land within permitted development rights.
Material and design
The use of materials and the design of the new conservatory should be in harmony with the existing property and its surroundings. It’s advisable to avoid materials or designs that may significantly impact the external appearance of the original house, or impede on the neighbouring property.
Conservation areas plus listed buildings
If your property is a listed building or built in a conservation area, additional restrictions may apply. In such cases, it’s essential to consult with the local planning authority.
Building regulations
While planning permission may not be necessary, building regulations approval is likely required. Conservatory building regulations ensure that the construction meets essential safety and energy efficiency standards.
Neighbour consultation scheme
In some cases, a Neighbour Consultation Scheme may apply. This involves notifying adjacent properties, and if there are no objections from a neighbouring property or otherwise within a specified timeframe, the conservatory can proceed.
Professional advice
It’s always advisable to seek professional advice, especially if your project involves unique circumstances or if you have concerns about compliance with relevant building regulations.
Alternative uses
Converting a conservatory into a habitable room, such as a bedroom, may require planning permission and compliance with building regulations. Consider the intended use of the conservatory and ensure it gets the relevant building regulations approval if required.
So, by being aware of these conditions and limits, homeowners can better navigate the process of installing a conservatory within the framework of permitted development rules. However, individual circumstances vary, so we recommend you consult with local planning authorities or professionals to ensure compliance with specific planning permission rules and regulations applicable to your property before submitting a planning application.
What size conservatory can you have without planning permission?
In many cases, homeowners can add a conservatory to their property without the need for planning permission, thanks to permitted development rights. However, it’s crucial to adhere to specific criteria to ensure compliance.
Size limitation
The conservatory should not surpass 50% of the total land area surrounding the original house. This means that if your property boundary is 200 square metres, the conservatory’s footprint should not exceed 100 square metres, as this would be more than half the size of the existing house boundary.
Projection boundaries
It’s essential to consider the projections of the conservatory. Specifically, the structure should not extend forward beyond the principal or side elevation of the original house. This ensures that the conservatory does not protrude too far into the outdoor space.
For example, imagine you own a property with a spacious garden. You decide to improve your living space by adding a rear conservatory to the back of your house. Here’s how the criteria come into play:
- Determining the size: Your garden measures 300 square metres. To comply with the permitted development criteria, the conservatory’s size should not exceed 150 square metres (more than half or 50%+ of the total land area). In this case, you plan for a footprint of 120 square metres, meaning the conservatory covers less than half the width of your garden and is well within the permissible limits.
- Positioning considerations: Examining the layout of your existing house, you ensure that the conservatory extends no further than the side or principal elevation i.e. the rear wall or roof. By aligning it with the rear wall of the house, the conservatory integrates into the existing structure without projecting further forward than the attached house. You will also need to ensure the maximum height of the conservatory does not exceed the tallest part of the existing property’s roof.
By carefully adhering to these criteria before the construction process begins, you can confidently proceed with your conservatory project, secure in the knowledge that it falls within the scope of permitted development rights.
Remember, while these criteria provide a general guideline, individual circumstances may vary, and it’s advisable to seek professional advice or consult local planning authorities for a precise assessment tailored to your property.
What is the 4 year rule for a conservatory?
The 4 year rule comes into play when dealing with extensions and conservatories. Essentially, if your conservatory has been in place for more than four years, it might be considered immune to planning enforcement.
Now, here’s the twist. While the 4 year rule seems straightforward, it has its complexities. The immunity it provides doesn’t mean an absolute green light; certain conditions and intricacies may apply.
It’s highly advisable to seek advice from a professional or your local council when navigating the ins and outs of this rule.
Consulting with an expert can help you determine whether your specific conservatory situation qualifies for this exemption. This can be particularly helpful if the conservatory was installed by a previous owner, as there may have been additional work you were unaware of.
They can guide you through the details, ensuring that you comply with all building regulations and avoid any unexpected issues.
Can you turn a conservatory into a room without planning permission?
If you plan to turn your conservatory into a more habitable room, you may need to apply for a change of use or seek building regulations approval. The process typically involves upgrading the conservatory’s structure to meet the same standards as a traditional extension. This means ensuring proper insulation, a solid roof, and compliance with building regulations.
The key is to improve the energy efficiency and overall build quality of the space. By replacing the standard conservatory roof with a more substantial and insulated one, like CosyPanels, you not only improve the room’s comfort and make it more energy efficient but also eliminate the need for additional planning permissions.
However, it’s essential to keep an eye on certain considerations, such as the size and location of your property, as these can affect the permitted development rights. As always, it’s best to consult with a professional or your Local Planning Authority to confirm your specific circumstances and ensure compliance with regulations.
