Average House Extension Costs 2024
It is important to understand that there are many factors that contribute to the overall cost of an extension. These include the size and type of extension, as well as any additional features or upgrades that may be included.
The average cost of an extension can vary vastly between £25,000 – £100,000.
The size and type of extension greatly impact how much the extension will cost. A single-storey extension will generally cost less than a double-storey extension, as it requires less materials and labour.
Similarly, the more square metres you add to your home, the higher the cost will be. This is because larger extensions require more materials and labour to construct.
Another factor that can significantly affect the cost your extension is any additional features or upgrades you choose to include.
For example, adding a kitchen extension will increase the cost as the room will require specialised plumbing and electrical work. Similarly, choosing high end finishes and materials will also add to the cost of the project.
It is also important to keep in mind that house extension costs can vary greatly depending on location. In areas where labour and material costs are higher, the overall cost of an extension will also be higher.
In some cases, you may be able to save money on your house extension by comparing quotes from different builders. However, it is important to note that the cheapest quote may not always be the best option.
It is essential to carefully review each quote and ensure that all necessary factors have been taken into account. This will help you avoid any surprise costs or delays in the construction process.
Single Storey Extension Cost
On average, a single storey extension could cost between £25,000 – £50,000 depending on the size and other specifications.
A single storey extension is a popular way to add more space and value to your home. It involves constructing an additional room or living area on the ground floor of your existing property, without adding another level.
This type of extension can be built onto any side of your house, whether it’s at the front, back or side.
Single storey extensions are known for being a cost-effective option compared to multi-storey extensions, making it a popular choice among homeowners.
One of the main benefits of a single storey extension is the extra living space it provides. This can be used for a variety of purposes, such as creating an open-plan kitchen and dining area, adding a home office or study, or even building an additional bedroom.
This extra space can significantly improve the functionality and flow of your home, making it more suitable for your current lifestyle.
Two Storey Extension Cost
Typically, a basic two-storey extension costs between £40,000 – £100,000.
A two storey extension is a type of home extension that adds two floors to the existing structure. It involves building additional rooms or living space above an existing ground floor.
This type of extension can be added to both detached and semi-detached homes, providing more flexibility in terms of design and layout.
There are many benefits to opting for a two storey extension. Firstly, it can significantly increase the value of a property, making it a wise investment.
Another advantage of a two storey extension is that it provides more design possibilities compared to other forms of extensions.
With two floors, there is more room for creativity and customisation, allowing homeowners to create their dream space according to their needs and preferences.
Rear Extension Cost
The average rear extension cost depends on various factors such as size, materials used and the complexity of design. Generally, you could expect to pay anywhere from £25,000 – £50,000.
A rear extension is the most common type of house extension that involves extending the living space of a property towards the back.
One of the main benefits of a rear extension is that it allows homeowners to customise their living space according to their specific needs and preferences.
Whether it’s adding an extra bedroom, extending the kitchen for more storage and counter space, or creating a home office or playroom, rear extensions offer endless possibilities.
It must be noted that a rear extension can sacrifice your outdoor space. But by extending towards the back, homeowners can create more room for their families to grow and enjoy.
A well-designed rear extension can seamlessly blend indoor and outdoor living, creating a more spacious and inviting home.
Side Extension Cost
Generally speaking, a basic side extension will typically cost around £30,000 – £60,000.
Side extensions are a popular way to add more living space to your home without sacrificing the precious outdoor area.
By building a side extension, you can utilise the unused space on the side of your property to create more livable space.
This is especially useful for homes with narrow gardens or limited backyard space. By extending outwards instead of upwards, you can maintain the size and functionality of your outdoor area while still gaining additional indoor living space.
Furthermore, a well-designed side extension can actually enhance your garden experience. With the right placement and design, a side extension can create a seamless flow between indoor and outdoor living spaces.
Moreover, side extensions offer the opportunity for creative and unique design choices. From modern glass structures to traditional brickwork, there are various ways to incorporate a side extension that complements the existing style of your home.
Wraparound Extension Cost
The average wraparound extension costs between £50,000 – £100,000.
A wraparound extension is perfect for those who have limited outdoor space but still want to add more square footage to their home.
The main benefit of a wraparound extension is that it maximises the use of your existing space. Instead of adding an extension at the back or side of your home, which can limit natural light and access to your yard, a wraparound extension utilises both areas for maximum functionality.
This means you can have more rooms or create an open-plan living area without sacrificing outdoor space. It is also a more cost-effective option compared to building separate extensions on different sides of your home.
When it comes to design, a wraparound extension offers more flexibility and options compared to other types of extensions.
You can choose to create additional bedrooms, a larger kitchen or dining area, or even add a home office or study. The possibilities are endless depending on your specific needs and preferences.
Save Money on Building an Extension Project
Building an extension is time-consuming and it requires a substantial amount of money. However, there are ways to save money when building a house extension without compromising on the quality and design of your new space.
The first tip to save money when building a house extension is to carefully consider the size and design of the extension.
While it may be tempting to add as much space as possible, keep in mind that your project will be charged per square metre. Plus if your extension is small enough to be built within permitted development, you will avoid the extra costs associated with attaining planning permission.
Instead, think about your needs and priorities and plan accordingly. By carefully considering these factors, you can save money on both materials and labour costs.
Another way to save money when building a house extension is to be open about your budget with your builder.
This will not only help them come up with a realistic estimate but also allow them to suggest alternatives and cost-saving measures.
They may have worked on similar projects in the past and can offer creative solutions that fit within your budget.
Also, be sure to get multiple quotes from different builders as prices can vary significantly. Don’t just go for the cheapest option, but make sure you consider their experience, reputation and customer reviews as well.
Lastly, don’t overlook the importance of proper planning and research before starting your house extension project.
By carefully considering all aspects of your extension, consulting with professionals and getting multiple quotes, you can save money without compromising on quality.
Remember that a well-planned and executed extension can add significant value to your property in the long run. So take the time to make informed decisions and ensure that your extension is built to last.
