If your home feels a little too snug or you’re dreaming of a new open-plan living area, a dedicated workspace, or a larger kitchen and dining room, a single storey extension could be the perfect solution. These thoughtfully designed projects offer extra space, improved functionality and a real boost to everyday living – all without the upheaval of a full renovation.
At Single Storey Design, we help homeowners across the South plan, design and build high-quality single storey additions tailored to how they live. Whether you’re just starting to explore the idea or you’re ready to get going, here’s everything you need to know.
What Is a Single Storey Extension?
A single storey extension is a one-level addition added to your existing property. These extensions can take many forms depending on your needs – from kitchen and dining extensions to garden rooms, utility spaces or larger living areas.
With careful design and expert construction, a well-executed extension can feel like a seamless part of your home rather than an add-on.
Why Choose a Single Storey Extension?
More Space Without Moving Home
Rather than juggling with limited square footage or relocating to a bigger property, a single storey extension creates the space you need where you already live. Whether you’re growing your family, working from home, or simply want more room to enjoy, extending brings that valuable space without the stress of moving.
Flexible Design Options
Single storey extensions are highly adaptable. They can be:
- Open-plan kitchen/dining areas
- Family or living rooms
- Home offices or studios
- Utility and boot rooms
- Indoor/outdoor living spaces with bi-fold or sliding doors
Your extension can be tailored to how you live now and how you expect to use the space in the future.
Improved Natural Light and Flow
Many extensions feature large glazing options such as glazed roofs, lanterns, or full-height windows, bringing in abundant natural light and creating a strong connection with your garden or outdoor space.
This creates a brighter, more welcoming interior and enhances the overall feel of your home.
Increase Property Value
A well-designed extension not only improves your quality of life but also adds real market value to your home. Homeowners often see strong returns on investment when renovating to increase usable space.
What’s Involved in the Process?
Every successful extension project starts with careful planning and clear communication. Here’s how we typically work with our clients:
1. Initial Consultation
We’ll discuss your goals, budget and how you expect to use the space.
2. Design & Planning
Using your ideas, we create a tailored design that complements your property’s style and meets local planning requirements.
3. Approvals & Regulations
We’ll guide you through planning permission (where required) and building control compliance to make the process smooth and stress-free.
4. Construction
Our experienced team manages the build from start to finish, keeping your home tidy and minimising disruption.
5. Finishing Touches
Once the build is complete, your new space is finished to a high standard and ready to be used and enjoyed.
Planning Permission and Building Regulations
Most single storey extensions fall under permitted development rights, meaning you may not need formal planning permission – particularly if the extension meets specific criteria around size and design. However, building regulations approval is typically required to ensure structural safety, insulation, energy efficiency and compliance with electrical and drainage standards.
The team at Single Storey Design will advise you on what applies to your project and support you throughout the approval process.
Design That Works for You
One of the biggest advantages of a single storey extension is how well it can be tailored to your lifestyle. From traditional homes to contemporary properties, extensions can be designed to complement existing architecture while giving you the additional space you need.
Whether you’re aiming for a cosy family room, a bright kitchen extension, or seamless indoor-outdoor living, the design possibilities are almost endless.
