Single storey extensions are incredibly versatile, available in a variety of shapes and sizes, and adaptable to different budgets. These extensions can completely transform the layout of your home, offering additional space for everything from an extended kitchen to a new living area. If you’re curious about what goes into building a single storey extension, you’ve come to the right place. Let’s dive into everything you need to consider before starting your project, including costs, design options, and planning permissions.
Why Build a Single Storey Extension?
A single storey extension is a cost-effective alternative to moving house. With the rising costs of real estate, extending your current home can be a more affordable solution. When purchasing a new property, you need to budget for expenses like stamp duty, legal fees, estate agent fees, and mortgage costs—not to mention the deposit and insurance. By contrast, a well-designed single storey extension can meet your need for extra space at a fraction of the cost of moving while avoiding the hassle of relocating.
In addition to being budget-friendly, a single storey extension adds value to your property. Homes with additional living spaces, such as a larger kitchen or extra bedroom, are more attractive to buyers, making it a sound investment for the future. You can also customize the design to suit your lifestyle, adapting to new family needs or creating a space that aligns with modern trends in home living.
Types of Single Storey Extensions
1. Rear Extension
A single storey rear extension is one of the most popular types, typically used to expand kitchens or dining areas. Under permitted development rules, you can extend up to 3.0 meters from the rear wall of your house without needing planning permission. With a range of roof options—like flat or pitched roofs—you can create a stylish and functional extension that blends seamlessly with your existing home.
2. Side Extension
A single storey side extension can help you make use of the unused space alongside your house. This type of extension is ideal for creating new rooms such as a downstairs bedroom with an ensuite or an extra reception room, making your home double-fronted in some cases. Depending on your property’s layout and local regulations, side extensions can either reach your boundary fence or be limited to half the width of your house.
3. Wrap-Around Extension
The wrap-around extension is a combination of a side and rear extension, making it the go-to choice for semi-detached homes. It wraps around the corner of your property, offering endless possibilities for internal layout redesigns. Whether you’re looking to expand your kitchen, add a home office, or create an open-plan living space, a wrap-around extension can provide the additional space and design flexibility you need.
Other Considerations for a Single Storey Extension
When planning your single storey extension, there are several key elements to think about:
Roof Options: You can choose between flat, pitched, or even skylight-integrated roofs, depending on the aesthetic and practical needs of your home.
Windows and Doors: The style and placement of windows and doors play a major role in how your extension will look and function. Consider options that bring in natural light while complementing the overall design of your home.
How Much Does a Single Storey Extension Cost?
The cost of a single storey extension can vary significantly depending on several factors:
Size: Larger extensions will naturally cost more due to the additional materials and labour required.
Complexity: Unique design features or complex structural alterations can increase the overall cost.
Materials: The choice of high-end materials like premium bricks, roofing, or luxury fixtures will elevate the price.
Quality of Contractor: Hiring a reputable contractor can affect the cost, but it’s worth investing in a team that will deliver a quality build.
Location in the UK: Building costs vary by region, with projects in London or the South-East generally being more expensive than in other parts of the UK.
Condition of Soil & Existing Building: Poor soil conditions or issues with your existing building’s structure can result in additional costs for groundwork or reinforcements.
On average, you can expect to pay anywhere from £1,500 to £3,000 per square meter for a single storey extension, but this can increase depending on the factors mentioned above.
Conclusion
A single storey extension is a fantastic way to enhance your home, whether you need more living space, a bigger kitchen, or a modernised layout. With various types of extensions to choose from and the ability to tailor your design to fit your budget, it’s an excellent investment that adds both space and value to your property. By carefully considering your design options and planning your budget, you can create a functional and beautiful extension that suits your lifestyle.
