Wraparound Extensions: Transform Space
Transform your home with a wraparound extension. Discover design ideas, costs, and how to navigate the planning and building regulations process.
In the world of home improvements, there’s few projects that are as life changing as a wraparound extension, offering more living space and more value. This popular design option gives you the chance to add to your home in a way that wraps around the existing house and garden.
A wraparound extension is where a rear extension meets a side extension, creating one seamless addition that wraps around two sides of the property. This design gives you more living space and a versatile area that can be used as a kitchen, dining room or additional living space.
To get the full benefits of a wraparound extension you need to navigate a few things, from build costs to design aesthetics. You need to consider the planning permission, regulations and sustainable building practices that will impact on your budget and outcome.
This is your guide, step by step plans for a wraparound extension, with the benefits, challenges and styles. Whether you’re an experienced builder or a first time homeowner, this will help you make informed decisions every step of the way.
A wraparound extension is a type of home addition that combines a side infill with a rear extension, creating an L shape. This type of extension can be applied to any house style, adds 15 to 60 square meters of living space. It can be a single or double storey build, depending on your needs and the space available.
The beauty of a wraparound extension is that it can turn under utilised side returns and rear areas into living space. And it doesn’t take up too much of your garden, which is a big consideration for homeowners who want to keep their outdoor space.
One of the big advantages of wraparound extensions is the amount of natural light they can bring into a home, both aesthetically and in terms of feeling of space. The merging of indoor and outdoor space through modern design can really lift the ambiance of a home.
In urban areas the wraparound extension has become a practical solution to space issues, especially where side returns are a common feature of residential properties. This type of extension not only adds living space but also gives you many design options to suit the needs of urban dwellers.
A wraparound extension is a popular type of extension that gives homeowners many benefits for their living spaces. Firstly it utilises the underused side alleyways and the rear of the property so you can add a large amount of living space without taking up too much of your garden. This type of extension opens up the opportunity for modern open plan layouts that are perfect for a seamless kitchen and dining area, for a more functional and social space.
Wraparound extensions often have features like bi-fold or large glass doors which not only add to the aesthetics but also brings in more natural light, brightening up the home and the indoor outdoor connection. These features can make the home feel more spacious and welcoming.
And the L shaped space created by a wraparound extension gives you the opportunity for extra facilities in the home. You can have additional bathrooms, more storage areas or even multi purpose spaces that can be a utility room, home office or a cozy living area.
In summary:
When considering extensions to your home it’s important to know the difference between planning permission and permitted development rights (PDRs). A wraparound extension, a popular type of extension that adds a lot of space by extending from the side return and around to the rear of the house, usually requires planning permission because of its size.
For smaller projects like a rear extension, detached houses can extend up to 8m and semi-detached or terraced houses up to 6m without planning permission under PDRs. But side extensions have restrictions: they must be single storey, no higher than 4m and no wider than half the original width of the house. And they can’t take up more than half of the garden space.
When a side extension is combined with a rear extension to form an L shaped wraparound this no longer falls under PDRs and planning permission from the local authority is required. And any existing conditions on the house can override PDRs and jurisdiction and you will need a full householder planning application. Always check these specifics before you start any extension project.
Remember when planning an extension always consult with a structural engineer to ensure the design for your extra living space meets building regulations and structural integrity.
When considering a wraparound extension for your home you need to know the various factors that will affect the overall cost of the project. The size of the extension will play a big part, larger extensions will cost more in materials and labour. The design choices you make, like adding glazing for more natural light or using premium materials will also have a big impact on costs. For example choosing timber or oak framing over bricks will change the cost profile of the wraparound extension.
Wraparound extensions usually require planning permission and the associated costs and timescales need to be factored in. The complexity of the design and the planning considerations, like how the extension will affect the visual amenity and privacy of the surrounding area will also impact on the design and therefore the cost.
Also the type of property you own will affect the price, flat roof extensions will start from around £90,000 and semi-detached houses from £150,000. These prices will vary depending on the project specifics, extra living space or modern design elements you want to add.
The cost of construction materials for a wraparound extension will vary depending on the quality and local availability of materials. Bricks, concrete, timber, glass and steel are some of the materials that will be used and each has its own price. Choosing higher end materials for a modern design or eco friendly elements will increase the material cost.
Adding extra spaces like a dining area or extra bedroom will increase the material cost as more materials will be required. Remember material prices are subject to market fluctuations and regional availability which will affect the overall cost of the project. So the choice and sourcing of construction materials need to be planned thoroughly.
Along with material and construction costs professional fees will also be a big chunk of the budget for a wraparound extension. These fees will cover the services of architects, structural engineers, surveyors and possibly project managers. A general guide is to set aside an additional 10-15% of the construction cost for these professionals fees; for example this would be £9,000 for professional fees at 15% on a base cost of £60,000.
Also VAT is another expense, usually 20% which will add an estimated £12,000 or more to the total cost before VAT is applied. If the wraparound extension has a kitchen the installation cost will be an extra expense. A basic kitchen fit out will start from £10,000 including low to mid range appliances.
When calculating the cost of a wraparound extension you should budget for a contingency – usually around 20% of the total cost – to cover any unexpected expenses that will arise during the construction process.
The cost of a wraparound extension will be affected by the location of your property. Local factors like labour costs, demand for services, regulatory fees and material prices will vary across different regions. Construction projects including wraparound extensions are more expensive in London and the South East. The North of England and Wales are more affordable.
Also application fees for planning permissions and other regulatory costs will vary with the local planning authority which will affect the overall budget for your wraparound extension. Given these regional differences in costs you should research the specific conditions in your area to get an accurate estimate for your project.
Dealing with regulations is a key part of the process for homeowners looking to do a wraparound extension. Wraparound extensions usually require full householder planning application so understanding and complying with the local authority regulations is crucial. It’s rare for wraparound extensions to fall under permitted development rights as they are too big and complex. Factors that will be considered for planning permission include loss of light to neighbours, visual impact on the surrounding area and overall impact on the character or appearance of the local area.
It’s recommended to get a reliable architect or planning consultant to help you with the local planning laws. Their expertise will increase the chances of getting the necessary approvals. Beyond planning permission homeowners will also need to comply with building regulations. These ensure the work is safe and meets performance standards. If the wraparound extension affects adjoining properties party wall agreements must be in place before work starts.
For wraparound extensions the Party Wall Act is key. It states that homeowners must serve a notice to their neighbours before commencing any construction work that will affect a shared wall or boundary. This is particularly important in England and Wales where many properties share boundaries with adjacent buildings.
The Act applies in various situations including when excavating near to neighbouring buildings or modifying shared boundaries regardless of the amount of work involved. Specifically construction work that involves excavations within 3-6 metres of a neighbouring property depending on the depth of the new foundations is notifiable under this Act. Non compliance with the Party Wall Act can result in financial penalties, disputes with neighbours and potentially legal action.
During the planning phase of a wraparound extension the impact on natural light for neighbouring properties should be carefully considered. A poorly designed extension can block sunlight and cause disputes and planning permission issues. Choosing pitched roofs instead of flat roofs will reduce the risk of blocking light to adjoining properties.
Maintaining a neighbour’s access to natural light is not only considerate but also a key part of getting planning permission. Local authorities may impose specific restrictions on wraparound extensions to preserve the right to light for neighbouring homes. So working with planning professionals who are knowledgeable about light rights will keep neighbourly relations intact and meet the legal requirements.
When considering a wraparound extension the style you choose will impact both the look and the cost of the project. Wraparound extensions wrap around the side infill and rear of a property creating an L shape that improves spatial dynamics and property looks. This type of extension gives homeowners the flexibility to cater for all styles of architecture and add extra living space that fits with both traditional and modern designs.
The decision making process should include consideration of layout options. For example an open plan kitchen can change the living space into a social hub for family interaction and add bedrooms to cater for a growing family’s need for private space. The choice extends to materials and finishes with timber or oak being more cost effective than brick. And choosing the right roofing, insulation and windows is not just a stylistic decision but also crucial for the energy efficiency and comfort of the new living space.
Cost will always be a factor in your wraparound extension’s style. While some materials and designs may seem cheaper upfront, consider the long term energy savings from better insulation and quality materials too. With so many styles and materials to choose from homeowners are advised to have a clear idea of what they want and work with architects and designers who understand their design tastes and budget.
Wraparound extension exterior design inspiration can range from traditional approaches that match the existing house materials to bold, modern designs that contrast old with new. A pitched roof with Velux windows will keep in line with the existing architecture but give a fresh look.
Homeowners looking for a modern twist may prefer rendered walls with large bi-fold or sliding doors which will create a clean, modern contrast especially on traditional Victorian properties. For those who want to be more adventurous zinc cladding or a minimalist finish will give a sleek and unique extension style.
Roof lanterns are a design feature that add to the look but also flood the living space with natural light and aid wellness and energy efficiency. For a more edgy design industrial style inspiration can incorporate exposed brickwork which gives character and texture to the exterior of the extension.
Achieving the balance between aesthetics and functionality is key to any home extension project. The wraparound extension is a perfect example, utilising the underused side return space and extending the back of the house into an L shape that adds a large amount of extra living space. This type of extension is also very unobtrusive as it rarely takes up significant garden space.
Getting the structure calculated by a professional structural engineer is key to a successful build that looks and feels good. With the extra space wraparound extensions offer many design possibilities. They can be open plan living and dining areas adding sociability to the home or transform into specialist rooms like playrooms or home offices to suit individual lifestyles.
The inclusion of design elements like large sliding doors or roof lanterns will bring in more natural light and strengthen the connection to the outdoors and make the most of the space. As the design comes together it will show how careful planning and clever design can result in a wraparound extension that is a perfect combination of form and function – adding to the home not just in square footage but in living space.
Wraparound extensions are a popular choice for homeowners who want to add to their property without losing too much outdoor space. Structurally they combine the side and rear extensions to form an L shape that joins onto the back of the house. This type of extension can add anywhere from 15 to 60 square meters of extra living space making it a versatile solution for those who need more room.
There are two main types of wraparound extensions: single storey and double storey. Single storey wraparound extensions extend only the ground floor, adding space for areas like kitchens, dining rooms or extra family living areas. A double storey wraparound involves building over two floors, which could include adding extra bedrooms or bathrooms on the first floor and the extra ground floor space.
Wraparound extensions work well in homes that have unused or dead space next to the property, like the passages next to terraced or semi detached houses. By extending into these areas you can add a lot more floor space to the property without reducing the garden space.
Designed well a wraparound extension will not only increase the footprint of the house but also bring in more natural light and create a stronger connection to the garden or outside space and often add value to the property both financially and lifestyle.
Single storey wraparound extensions are a quick and popular way to add that extra space on the ground floor of the house. They extend to the side and rear of the property in an L shape. This type of extension is perfect for homeowners who want to increase the size of their living areas without losing too much of the garden.
One of the benefits of single storey wraparound extensions is they may fall under permitted development rights which means homeowners may not need formal planning permission if the design meets certain conditions. For example the extension can’t occupy more than half the land around the original house and can’t be within the prescribed distance from the original rear wall of the house.
There are specific measurements that govern the size of a single storey extension without the need for planning permission. For terraced or semi detached homes the extension can’t be more than 3 meters from the original rear wall and up to 4 meters for detached homes. It also has to comply with the maximum height and boundary regulations.
For homeowners who want to add a lot more living space double storey wraparound extensions can be a game changer. This type of extension spans over two levels of the house, so you can add entirely new rooms like extra bedrooms, larger kitchens, additional bathrooms and more on the ground and first floor.
Although the cost of a two storey extension is higher than a single storey extension the investment can be worthwhile. The cost per square meter for a two storey build is slightly higher than a single storey extension but can almost double the floor space and potentially be better value in the long run.
Besides the massive increase in space a two storey extension can also have a big impact on a family’s lifestyle. These types of extensions can accommodate the changing needs of a growing family so homeowners can enjoy their home for many years without having to move to a bigger house.
When considering a two storey wraparound extension you need to consider planning permission and building regulations as it will likely require full planning permission. Homeowners should speak to the local planning authority and often a structural engineer to ensure the build is done safely. These are a big project but with proper design and execution they will be a valuable addition to any home.
When building a wraparound extension or any type of home extension sustainability is good for the environment and can be cost effective in the long run. To achieve a sustainable build you need to incorporate eco friendly design and construction practices that improve the thermal performance of your home. This can mean opting for a non open plan layout with visible structural elements like columns which saves money and reduces greenhouse gas emissions while still being functional.
Also using construction methods like timber frame and structural insulated panels (SIPs) is a greener alternative to traditional building methods and can be faster to build. Reusing materials and fixtures from the old parts of your home will reduce the overall carbon footprint of your extension. Reclaimed bricks can maintain the look and feel of older homes and reduce waste.
Also fitting your new extension with energy efficient appliances and considering renewable energy sources like air-source heat pumps or solar photovoltaic (PV) panels will further your commitment to sustainability. Not only will these reduce your ongoing energy costs but will also make for a more environmentally friendly living space.
Eco friendly building materials are the foundation of sustainable building. Methods like timber frame and structural insulated panels (SIPs) are becoming more popular due to their lower environmental impact and efficiency benefits. Timber is a renewable resource and when sourced responsibly it can be a carbon sink and sequester carbon from the atmosphere. SIPs provide great insulation and strength and create a tight building envelope that reduces energy waste.
Giving old materials from demolished structures a second life is another way to be eco friendly in your build. Salvaged wood, repurposed fixtures and recycled metals can all be used in your new extension without the environmental cost of new production. And using sustainable and locally sourced new materials will further reduce the ecological footprint.
Energy efficient appliances need to be integrated during the build phase – these will reduce the overall greenhouse gas emissions of the extension. Often overlooked is the sourcing and manufacturing process of any new appliances so need to be considered when making your choices.
When planning a wraparound extension insulation is key to energy efficiency. Options are fiber, foam or extruded PVC insulation each with its own benefits in preventing energy loss. You need to seal the building properly so that costly heating or cooling doesn’t escape through gaps.
Choose high quality energy efficient doors and windows like uPVC to minimize heat transfer and contribute to the environmental performance of the extension. These will also come with the added benefit of better sound insulation and increased security.
The materials used for the extension should match the style of the existing property and support energy efficiency goals. This will ensure the new build doesn’t compromise the thermal performance of the original building. Also the design should maximise natural light to reduce dependence on artificial lighting and therefore energy consumption.
Working with architects who are familiar with energy efficient designs will ensure the wraparound extension is both form and function. They may also have access to the latest sustainable building techniques and materials.
In summary a well thought out approach to sustainability during the build of a wraparound extension will not only protect the environment but also the occupants living conditions and reduce energy costs in the long run.
A wraparound extension cleverly combines a rear extension with a side return extension to make the most of unused or underused space in your property to create an L shaped addition. This will ensure every inch is used and give you more square footage to improve your home’s functionality and looks. A well thought out design in a wraparound extension can incorporate features like open plan living areas, plenty of natural light through large windows and materials that blend in with the existing style of the house.
While planning permission is a big factor for wraparound extensions, some smaller single storey extensions may not need planning permission as they fall within the permitted development rights. These rights define size and proximity boundaries to the original dwelling and can speed up the process. Also high end design features like bi-fold doors or sky grazing roof lanterns can enhance the functionality and looks of the extension. This will bring in more light and connection to the outside views and overall improve the living experience. However surveys show that adding a wraparound extension adds value to the property – a well done kitchen extension can increase the value of your home by as much as 13%.
A wraparound extension is the perfect opportunity to reconfigure your home’s space. This transformation can give you an open plan kitchen or separate but flowing living and dining areas to fit your modern lifestyle. By utilising underused areas like side alleys the extension will increase internal space without reducing garden space.
Structural calculation and planning are key to creating a space that’s not just bigger but smarter, the extension will be designed to fit your needs – from cozy bedrooms to practical utility rooms. The flexibility of design is evident in the various dimensions a wraparound extension can take from 15 to 60 square meters single or double height. This flexibility is crucial in creating a space that meets your needs today and tomorrow and bridges the indoor and outdoor and makes your home more livable.
Nationwide’s research shows the link between home improvements like extensions and property value; for example adding a double bedroom with an ensuite can increase your home’s value by up to 23%. In line with these findings a wraparound extension can add 10-15% to your property’s value depending on size, build quality and materials used in the extension.
Extensions that add to the kitchen or a single storey rear extension can add around 13% to the property’s value. It’s worth noting that the professional fees for the construction of a wraparound extension will impact the overall cost and therefore the perceived value of the property after the extension. From a design perspective the choice of materials – whether it’s the charm of timber or the tradition of brick – will not only affect the build cost of the extension but also the marketability and value of the property.
A wraparound extension is a great opportunity to add extra living space to your home. To make it a success you need to engage with architects and planning consultants especially if your home is a listed building. Research your property’s history before submitting a householder planning application to your local planning authority.
A wraparound extension takes 3-4 months to build depending on the project. This type of extension will turn your redundant outdoor space into a L-shaped living area and will add 10-15% to your property’s value, a figure dependent on size, build quality and materials used.
Wraparound extension costs are significant, £2000-£3000 per square meter so project budgets are £40,000-£180,000 depending on the size and complexity of the project.
