Wraparound Extensions London & Surrey: An Expert’s Guide

This style of extension wraps around the side and rear of your property, giving you the best of both worlds by expanding multiple areas of your home. Whether you want a larger kitchen, more living space, or a home office, a wraparound extension can make it happen, all without having to move house.

What is a Wraparound Extension?

A wraparound extension combines a single storey side return and a rear extension into an L-shaped layout, making it ideal for homes in urban areas like London where space is at a premium. It can add valuable square footage to both the back and side of your home, which is particularly useful if your property sits on a corner plot or has space on the side.

Wraparound extensions are especially popular in London & Surrey because they allow homeowners to maximise the use of their plot without extending upwards or outwards into the garden too much. It’s like creating a seamless flow from one part of the house to another, without cutting into outdoor space more than necessary. Plus, they often give homes a much more open-plan feel, perfect for modern living.

Planning Permission vs Permitted Development for L-Shape Extensions

In most cases, you will need planning permission for a wraparound or L-shape extension in London, as it alters both the side and rear of the house. However, depending on the size of your planned extension, you might be able to proceed under permitted development rights, which don’t require full planning permission. If the extension is within certain limits (e.g., no more than 3 metres from the rear wall and not taller than 4 metres), you could sidestep planning approval.

It’s always worth checking with your local council or on the planning portal to clarify if your project falls under permitted development. Alternatively, an architectural practice like DeVis Architecture can help guide you through the process, making sure all regulations are met and paperwork & planning permission drawings are properly handled.

Double Storey Wraparound Extensions: Maximising Space

A double storey wraparound extension offers incredible potential to maximise your space. It gives you not just one but two floors of extra room. This type of extension is perfect if you need additional living space on the ground floor. Uses include a larger kitchen or open-plan area, while also adding extra bedrooms or a bathroom upstairs.

Not only does a two storey wraparound extension significantly increase your home’s square footage, but it also enhances its overall value. By seamlessly blending with the existing structure, this extension creates a natural flow throughout the house, offering flexibility in design and layout.

How Much Do Wraparound Extensions Cost?

House extension cost is always a key factor when considering a home extension, and wraparound extensions in London can vary in price depending on size, design, and materials. As a rough estimate, the cost of a wraparound extension typically starts from £70,000 and can rise depending on the size complexity of the project.

How Much Does a Wrap-Around Extension Cost in the UK?

The cost of a single-storey wrap-around extension in the UK can vary significantly depending on several factors, and high-end finishes, bespoke features, and additional structural work will naturally add to the total. Here’s what you need to consider:

1. Size and Scope of the Project

The size of your extension will have the biggest impact on cost. Naturally, larger extensions require more materials and labour, which increases the price.

2. Location

Where you live plays a big role in the cost of construction. Building in London or other high-demand areas tends to be pricier than in other parts of the UK due to higher labour and material costs.

3. Construction Materials

The type and quality of materials you choose will also affect your budget. Premium finishes or bespoke materials will push up the price, while more standard options can help keep costs manageable.

4. Complexity of the Design

The more complex the design, the higher the cost. For example, incorporating features like glass ceilings or large bifold doors often requires input from structural engineers and specialist materials, which can add to the final bill.

5. Choice of Contractor

One of the most crucial factors is the contractor you choose. A reliable, experienced building firm will not only provide a high-quality finish but also help avoid unexpected delays or issues that could escalate costs.

How to Keep Costs Down

Keep in mind that the cost of planning permission, building control, and professional fees will also need to be factored into your budget. To minimise expenses, it’s essential to work with professionals who have experience in your type of project. At DeVis Architecture, we’ll guide you through the most cost-effective and creative solutions to maximise your space without breaking the bank.

Design Ideas for Wraparound Extensions

One of the most exciting aspects of a wraparound extension is the versatility it offers in design. Here are a few creative ways to make the most of your new space:

• Open-Plan Kitchen-Diner: One of the most modern design trends, this layout blends your kitchen and dining area into one expansive, bright room. It’s perfect for hosting and everyday family life.
• Home Office: With more people working remotely, a wraparound extension can provide the extra space needed to carve out a quiet, private home office.
• Lounge Area: You can use part of the extension to create a cosy living room or chill-out zone that overlooks the garden with large bi-fold doors.
• Utility Room: A practical addition to any busy household, a wraparound extension can allow for a separate utility room, freeing up space in the kitchen.
• Second Bathroom: If your family is growing, adding a second bathroom or even a luxury en-suite can be a brilliant use of your wraparound extension.
• Extended Elevation: With a new, extended rear elevation, you have the opportunity to stray away from overused bifold doors and opt for some interesting glazing, for example an up-&-over window with bench seating.

Remember, this is where DeVis Architecture comes in handy. We can help you plan a space that perfectly suits your needs, maximising both the practicality and aesthetic of your extension.

Maximising Natural Light in Wraparound Extensions

Natural light is key in making your extension feel bright and spacious. London homes, especially terraced properties, often suffer from a lack of light, but a well-designed wraparound extension can solve that. Consider adding skylights or a glass roof to flood the new space with sunlight. Bi-fold doors leading to the garden are another great option. They bring the outdoors in and creating a seamless connection between your indoor and outdoor spaces.
