Should I bother doing a small house extension?
If you’re short on space but not quite ready to move, you might be considering a small house extension. The question is, “Is a small house extension worth it?” Over the years, I’ve worked on many small extension projects, and I can confidently say that even a modest addition to your home can make a big difference. However, whether it’s the right choice for you depends on your needs, budget, and how you plan to use the extra space.
What Is a Small House Extension?
A small house extension typically adds 10–20 square metres of space to your home. While it may not seem like much, this additional space can be used in a variety of ways, such as:
- Expanding a kitchen or dining area
- Adding a utility room or downstairs WC
- Creating a small home office or study
- Extending a living room to improve its layout
These compact extensions are often covered under permitted development rights, meaning you might not need planning permission to get started.
Benefits of a Small House Extension
1. Affordable Way to Add Space
Small extensions are generally more budget-friendly than larger projects, making them a cost-effective way to increase your living space. On average, you can expect to pay between £1,200 and £1,800 per square metre, depending on the materials and finishes you choose.
2. Minimal Disruption
Compared to larger projects, a small extension typically requires less time and causes less disruption to your daily life. This makes it a great option for busy households.
3. Increased Property Value
A well-designed small house extension can boost your home’s value by 5–10%. Features like a modern kitchen-diner or an additional utility space are particularly attractive to potential buyers.
4. Improved Layout and Functionality
Even a modest amount of extra space can transform how you use your home. For example, extending your kitchen by just a few metres can create room for a breakfast bar or additional storage.
Challenges of a Small House Extension
While small extensions have plenty of benefits, there are some potential challenges to keep in mind:
1. Limited Space
A small extension may not be enough to meet all your needs, especially if you’re planning for a growing family or need multiple new rooms.
2. Cost per Square Metre
The cost per square metre for small extensions can be higher than for larger ones due to fixed costs like groundwork and structural work. However, careful planning can help you get the most value for your investment.
3. Planning Restrictions
Although most small extensions fall under permitted development, it’s essential to check the rules for your property. If your home is in a conservation area or is a listed building, stricter regulations may apply. For more information, visit the Gov.uk Planning Permission page.
Ideas for Small House Extensions
If you’re thinking about a small house extension, here are some creative ways to use the space:
1. Kitchen Extensions
A small extension can provide room for additional storage, modern appliances, or even a cosy dining nook. Open-plan designs work particularly well for compact spaces.
2. Home Offices
With remote working becoming more common, creating a dedicated home office is a practical choice. Even a small extension can provide the privacy and quiet you need to work efficiently.
3. Utility Rooms
Adding a utility room keeps laundry and cleaning tasks out of your main living spaces, helping you maintain a clutter-free home.
4. Extended Living Areas
A modest addition to your living room can create space for a reading corner, play area, or simply make the room feel more open and inviting.
How to Maximise the Impact of a Small Extension
To make the most of your small house extension, it’s important to focus on smart design and efficient use of space. Here are my top tips:
1. Prioritise Functionality
Think about how you’ll use the new space and design it to suit your lifestyle. For example, built-in storage can help you make the most of limited room.
2. Use Natural Light
Adding features like skylights, bi-fold doors, or large windows can make a small extension feel bright and spacious.
3. Choose the Right Materials
High-quality materials that match your existing home create a seamless transition between old and new spaces, enhancing both aesthetics and value.
4. Work with Professionals
An experienced architect or builder can help you design a small extension that maximises space, complies with regulations, and fits your budget.
Are Small House Extensions Covered by Permitted Development?
In many cases, yes. Under permitted development rights, single-storey extensions can be built without planning permission as long as they meet specific criteria. For example:
- The extension must not extend more than 4 metres beyond the rear wall for detached homes or 3 metres for other types of properties.
- The height must not exceed 4 metres.

Final Thoughts: Is a Small House Extension Worth It?
For many homeowners, a small house extension is absolutely worth it. While it may not add a huge amount of space, the benefits of improved functionality, increased property value, and a better quality of living can make it a smart investment. With proper planning and thoughtful design, even a modest extension can have a big impact.
