Permitted Development for Side Extensions Explained

Understanding Side Extensions

Side extensions add living space to your home without full planning permission. They’re versatile, letting you expand your kitchen, add a dining area, or create an extra room.

A side extension is an addition to the side of your house, usually extending from an existing wall. These can be single-storey or double-storey, based on your needs and available space.

Why consider a side extension? Here are some benefits:

• More Living Space: Extra room for your family to spread out and enjoy.

• Higher Home Value: A well-done extension can increase your property’s worth.

• Customization: Design a space that fits your needs, like an open kitchen or extra bedroom.

Side extensions often fall under permitted development rights, saving you time and money on planning permission.

It’s crucial to understand these rights and ensure your project follows local rules. That’s where our expertise comes in. We’ll guide you through the process, ensuring your side extension is legal and hassle-free.

Permitted Development Rules for Side Extensions

Side extensions are a great way to add space to your home without the hassle of full planning permission. But there are some rules to keep in mind to ensure your project falls under permitted development rights.

Here are the key criteria:

• Height Restrictions: Your side extension can’t be taller than the highest part of your existing roof. For single-storey extensions, it must not exceed 4 meters in height.

• Width Limitations: The width of the extension should not be greater than half the width of the original house. This keeps the extension proportional and within the permitted development limits.

• Location Relative to Highways: Extensions should not front or face onto a highway. Basically, if your side extension would be visible from the road, it’s a no-go under permitted development.

• Coverage Area: The total area covered by your side extension and any other buildings must not exceed 50% of the land around the original house. This includes sheds, garages, and any other outbuildings.

• Single Storey Only: Side extensions must be single storey. If you’re thinking of adding a double-storey extension, you will need to go through the full planning permission process.

Planning Permission for Side Extensions

Sometimes, a side extension needs planning permission. This usually happens in protected areas like Conservation Areas, or if there are Article 4 Directions in place. But don’t worry, we’ll explain everything.

First up, the process. When your extension doesn’t meet permitted development rules, you’ll need to submit a planning application to your local authority. Here’s what you should know:

• Costs: Application fees vary, but expect to pay a few hundred pounds. This covers the administrative work your local authority will do to process your application.

• Timeframes: Typically, it takes about eight weeks for a decision. However, this can be longer if there are complications or if additional information is required.

• Documentation: You’ll need detailed plans of your proposed extension. These should show the layout, dimensions, and materials you plan to use.

• Consultation: Your local authority will likely consult with your neighbors. If they have objections, this could impact the decision.

• Appeals: If your application is refused, you can appeal the decision. This involves additional time and potentially further costs, but it gives you another chance to get approval.

• Compliance: Even if you get planning permission, you must still comply with Building Regulations. This ensures your extension is safe and meets all necessary standards.

Understanding when planning permission is needed and navigating the application process can seem daunting. But remember, it’s all about ensuring your project is legal and well-received by your community.

Special Rules for Protected Areas

Side extensions are fantastic, but if you live in a protected area, there are extra rules to keep in mind. These areas include Conservation Areas, Areas of Outstanding Natural Beauty, National Parks, and World Heritage Sites. Let’s break down what you need to know.

In these protected zones, permitted development rights are more restricted. Here’s why:

• Conservation Areas: These are places of special architectural or historic interest. The goal is to preserve their character, so side extensions usually require full planning permission.

• Areas of Outstanding Natural Beauty: These spots are all about protecting natural beauty. Any change, like a side extension, can impact the landscape, hence stricter rules.

• National Parks: These areas are set aside for their natural environment. Building works are closely monitored to maintain the park’s integrity.

• World Heritage Sites: These sites have global significance. Any modifications need careful consideration to preserve their unique value.

Specific restrictions in these areas include:

• Height and Size Limits: Even stricter than usual. You might find your extension has to be smaller or lower than what’s normally allowed.

• Materials and Design: Often, you’ll need to use materials and designs that fit with the existing character of the area.

Living in one of these areas means your project will likely need planning permission. This ensures your extension doesn’t negatively impact the special qualities of the area.

Understanding these rules is crucial, especially when considering more extensive projects. For example, if you’re looking into a two-storey rear extension, it’s important to be aware of the specific regulations that apply, such as height limits and distance from boundaries. Our detailed guide on two-storey rear extension rules provides comprehensive information on these requirements.

Building Regulations for Side Extensions

Building regulations ensure your side extension is safe, sound, and up to code. They cover various aspects to make sure everything is solid and compliant. Ignoring these could lead to big headaches down the line, so let’s break down what’s involved.

First off, safety. Your extension needs to meet standards for fire safety, including proper escape routes and fire-resistant materials. This isn’t just about passing inspections—it’s about protecting your family.

Structure is another key area. The extension must be strong enough to support its own weight and any additional loads, like furniture or snow on the roof. Structural integrity is non-negotiable.

Then there’s insulation. Proper insulation keeps your new space warm in winter and cool in summer. It also helps with energy efficiency, saving you money on bills. Good insulation includes walls, floors, and roofs.

Soundproofing matters too. Nobody wants to hear the washing machine while they’re trying to relax. Ensuring your extension has adequate soundproofing keeps the noise levels down.

Drainage and waste management. Your extension needs effective drainage to prevent water damage. This includes proper guttering and sewage systems to handle waste.

Access is another crucial factor. This covers everything from door widths to ensure easy entry and exit, to steps and ramps for accessibility.

Ventilation. Good airflow is essential for a healthy living environment. This includes adequate windows and possibly mechanical ventilation systems to keep the air fresh.

Meeting these building regulations isn’t just a box-ticking exercise. It’s about ensuring your side extension is a comfortable, safe, and valuable addition to your home. Our team can help you navigate these requirements, making sure everything is up to standard and ready for inspection.

Materials and Design Considerations

When planning a side extension, choosing the right materials and design elements is key. These choices ensure your extension complies with permitted development rules and blends seamlessly with your existing home.

Matching Materials

• Exterior Work: The materials used must have a similar appearance to those of your existing house. This means if your home has brickwork, your extension should use matching bricks. The same goes for roofing materials, windows, and doors.

• Consistency: Keeping the materials consistent helps the extension look like a natural part of your home, rather than an afterthought. This can also positively impact your property’s value.

Design Elements

• Roof Design: Your extension’s roof should complement the existing roofline. For single-storey extensions, a flat or pitched roof that matches the original structure works best.

• Windows and Doors: Use windows and doors that match the style and proportions of those in your existing home. This keeps the overall aesthetic cohesive.

• Finishing Touches: Pay attention to the smaller details like guttering, fascias, and soffits. These should also match the existing features of your home.

Practical Tips

• Planning Ahead: Before starting, take some time to plan your materials and design thoroughly. Ensure everything from bricks to roof tiles matches your current home.

• Consult Professionals: Getting expert advice can save you from costly mistakes. Our team can help you choose the right materials and design elements to ensure compliance with regulations.

• Sample Testing: If you’re unsure about matching materials, get samples and compare them to your existing home. This can help you make the best choice.

By focusing on these materials and design considerations, your side extension will not only comply with permitted development rules but also enhance the overall look and feel of your home.

Permitted Development Rights Removal

Local planning authorities can remove permitted development rights through specific conditions on previous planning permissions or by issuing Article 4 Directions. This can throw a wrench in your side extension plans if you’re not aware of these restrictions.

What should you do if you find out your permitted development rights have been removed? Here’s a quick rundown:

• Check Previous Permissions: Look at any planning permissions granted for your property. Conditions might be attached that limit your permitted development rights.

• Article 4 Directions: These are special directives that remove permitted development rights in specific areas. They’re often used in Conservation Areas or places of historical interest to maintain the character of the neighborhood.

• Consult Your Local Authority: If you’re unsure, contact your local planning authority. They can clarify whether Article 4 Directions or other conditions apply to your property.

• Apply for Planning Permission: If your permitted development rights are removed, you’ll need to go through the full planning permission process. This involves submitting an application, paying fees, and waiting for approval.

• Seek Professional Advice: Navigating these restrictions can be complex. Consulting experts, like our team, can help you understand the implications and guide you through the necessary steps.

Implications for your side extension plans? It means you might face additional time, costs, and paperwork. But knowing these rules upfront can save you from future headaches. Being well-prepared ensures your project stays on track, even if extra steps are needed.
