Home extensions come in many forms, but one of the most popular and versatile options is the single storey extension — also known as a ground floor extension. These extensions not only create valuable extra space but can also transform how your home flows and functions. Whether you are looking to expand your kitchen, add a dining area, or create a utility room, single storey extensions are a cost-effective way to increase your living space without moving home.
Why Choose a Single Storey Extension?
A single storey extension is one of the most popular ways to add extra space, light, and value to your home. Whether you’re dreaming of an open-plan kitchen, a spacious family room, or a seamless link to your garden, a ground floor extension can completely transform how you live. We design and build bespoke single storey extensions across West London and Buckinghamshire, blending practical layouts with stunning architectural design to create a space that feels effortless and modern.
Extending the ground floor of your home opens up a range of design possibilities. Many homeowners in West London and Buckinghamshire choose to build single storey extensions for new kitchen layouts, family rooms, or multifunctional spaces such as a home office or playroom. Our experienced team at Convert Extend UK manage every stage — from the initial design to the final build — ensuring your project is completed to the highest standard.
Where Do I Start?
When planning a single storey extension, start by identifying your priorities. What spaces do you need most — a larger kitchen, a dining area, or additional storage? Once your goals are clear, our design team will help you visualise how your new space will connect to your existing home layout, both aesthetically and practically.
During the design stage, it’s important to consider natural light, flow between rooms, and how the new area will be used daily. For example, many clients choose to include bi-fold doors opening to the garden or create an open-plan kitchen with a central island. Our experienced designers can help you explore all the possibilities while keeping your build practical and stylish.
Cost Effective?
A single storey extension can often be more cost-effective than a two storey extension because it typically requires less structural support and foundation work. However, if you think you might add an upper floor in future, we recommend designing suitable foundations from the start. This approach avoids the need for reinforcement later, helping you save money in the long term.
Planning Permission
Depending on the scope of your project, you may not need full planning permission for a single storey house extension. Many projects fall under permitted development rights (PD), which allow you to extend your property without submitting a formal planning application — provided you meet the specific size and design criteria.
At Convert Extend UK, we always advise checking with your local authority before starting work. If your extension qualifies as permitted development, we recommend applying for a certificate of lawful development for peace of mind. This confirms that your extension meets all requirements and protects you should you sell your property later.
PD rules include limits on overall height, depth, and materials, which must match the style of your existing property. If you plan to use modern or contrasting materials, or your build exceeds PD limits, you will need to apply for planning permission. Our team can guide you through both processes to ensure full compliance.
