Wrap Around Extensions: A Complete Guide

Is your home struggling to keep up with the demands of modern life? If you dream of a large, open-plan kitchen, a bright dining area, and an attractive and open connection to your garden, wrap around extensions could offer the ultimate solution. This ambitious style of extension is one of the most effective ways to dramatically increase your living space and completely transform your property’s layout.

A wrap around extension is a project that doesn’t just add a room, but reinvents your home for a new way of living. And at Abbey Partnership, we specialise in designing and building stunning wrap around extensions that unlock the true potential of our clients’ homes, adding significant space and value.

What is a Wrap Around Extension?

A wrap around extension is a clever combination of a side return and a rear extension, creating an ‘L’ shaped structure that wraps around two sides of your property. This type of extension is particularly well-suited to period properties, such as Victorian or Edwardian terraces and semi-detached homes, which often have a narrow, underutilised alleyway or ‘side return’ space.

By extending into this dead space at the side and simultaneously pushing the rear of the property outwards, a wraparound extension creates a substantial new area. This is the perfect opportunity to design a large, open-plan wrap around kitchen, dining, and living space. It allows you to remove the original rear and side walls of your home, resulting in a bright, expansive room that is often impossible to achieve with a standard rear extension alone. The result is a dramatic transformation that maximises both space and natural light.

Advantages of a Wrap Around Extension

Opting for a wrap around side return extension offers some of the most significant benefits of any home extension type, fundamentally changing the way you live in your home:

• A Dramatic Increase in Space: By combining two types of extension into one, a wrap around creates far more floor space than either a side or rear extension could achieve on its own. This allows for truly flexible layouts and the creation of multi-functional zones within a single, open-plan area.
• The Ultimate Open-Plan Living Area: This is the ideal solution for creating a large, sociable wrap around kitchen with an island, a generous dining area, and a comfortable family living space all in one. It turns the back of your home into its social heart.
• Vastly Improved Natural Light: Removing the original external walls and incorporating large bi-folding doors, sliding doors, and strategically placed rooflights can flood the new space and the centre of your home with natural light, eliminating dark corners.
• Adds Significant Property Value: A wraparound extension is a major project that adds considerable square footage and modernises a property’s layout. This makes it a highly desirable feature for future buyers and one of the best ways to add significant value to your home.
• Better Connection to the Garden: The L-shaped design provides exciting opportunities to connect with your garden. You can create two distinct access points or install a large expanse of glazing across the rear, blurring the lines between indoors and out.

How Much Does a Wrap Around Extension Cost?

Because of its larger size and the increased complexity of the structural work involved, the average wrap around extension cost is higher than that of a simple rear or side extension. As a hybrid of two extensions, it requires more materials, labour, and significant structural support to remove two external walls of the house.

The final cost will naturally depend on the overall size of the extension, the quality of the materials, the specification of the kitchen and bathroom fittings, and the amount of glazing. But as a guide, homeowners should budget from around £70,000 for a wrap around extension in the UK, though costs can be higher in London and the South East.

Wrap Around Extensions: Permitted Development and Planning Permission

Navigating the regulations for wrap around extensions is a crucial part of the process. Unlike some simpler extensions, they have specific rules that must be carefully followed.

Permitted Development Rights

It is a common misconception that you can combine the Permitted Development rights for a side extension and a rear extension to build a wrap around – unfortunately, this is not the case. As soon as a side and rear extension connect to form an ‘L’ shape, they are considered one single structure and the project will no longer fall under Permitted Development. Therefore, all wrap around extensions require a full planning application.

When Planning Permission is Required

As wrap around extensions do not fall under Permitted Development, you will always need to apply for full planning permission from your local council. The planning department will assess your application based on its potential impact on your neighbours and the surrounding area. Key planning permission considerations include:

• Loss of light or overshadowing to neighbouring properties.
• Overlooking and loss of privacy.
• The design, scale, and appearance of the extension and how it relates to the original house.
• The impact on the character of the street scene.

The planning application process typically takes 8-13 weeks. The team at Abbey Partnership has extensive experience in creating successful planning applications for wrap around extensions, designing them to meet local authority guidelines while fulfilling your vision.

Wrap Around Extensions: FAQs

Do I need permission for a wrap around extension? 

Yes. All wrap around extensions require a full planning application. They do not fall under Permitted Development rights because they combine both a side and rear extension into a single structure.

Is a wrap around extension worth it? 

Absolutely. While the initial investment is higher than for other extension types, a wraparound extension adds the most space and can dramatically improve your home’s layout and connection to the garden. This makes it a fantastic lifestyle investment that also adds significant value to your property.

Is a wrap around extension more expensive?

Yes. The wrap around extension cost is typically higher than a standalone side or rear extension. This is because it is a larger project, requiring more materials, more labour, and more complex structural work to support the removal of two of the original house walls.

How long do wrap around extensions take? 

The overall timeline can vary. The design and planning permission phase usually takes 3-4 months. The construction phase for a typical wraparound extension will then take approximately 4-6 months to complete, depending on the size and complexity of the project.

How close to the boundary can I build an extension? 

As wrap around extensions require planning permission, the distance to the boundary will be assessed by the local authority. They will consider the impact on your neighbours’ light and privacy. You will also need to comply with the Party Wall Act if you are building on or near the boundary line.

What is the difference between a side return and a wrap around extension? 

A side return extension fills in the narrow alleyway space at the side of a property, squaring off the back of the house. A wrap around extension does this and also extends further out to the rear, creating a larger, L-shaped addition.

Can I have a two-storey wrap around extension? 

This is possible but will be subject to much stricter planning considerations. The planners will be very concerned about the impact that a two-storey structure could have on neighbouring properties, making permission difficult to obtain.

What is a Party Wall Agreement and will I need one? 

A Party Wall Agreement is a legal agreement between you and your neighbours, required under the Party Wall Act 1996. You will almost certainly need one for a wrap around extension as the work will involve excavating for new foundations and building on or close to the boundary line.

Can a wrap around extension be built on a semi-detached house? 

Yes, wrap around extensions are very popular for semi-detached and end-of-terrace houses that have the necessary space at the side. The design will need to be carefully considered to ensure it complements the attached property.

What are the main design challenges with a wrap around kitchen? 

The main challenge is ensuring the large, open-plan space doesn’t feel dark in the middle. This is overcome with clever design, using large rooflights or a glazed roof over the old side return area to draw natural light deep into the home. Zoning the space with different flooring or lighting can also help define the kitchen, dining, and living areas.
