So, Is a Home Extension Worth It
If you’re running out of space but don’t want to move, a home extension can seem like the ideal solution—but many homeowners still ask, is a home extension worth it? The answer depends on your goals, budget, and long-term plans.
In this blog, I’ll break down the practical and financial pros and cons of extending your home, how to assess whether it’s the right option for you, and what to consider before starting the project.
Why Consider a Home Extension?
Extensions can add significant space to your property, improve layout, and boost property value. They’re especially popular with families needing more room or homeowners working from home who require dedicated office space.
With the right design and build quality, an extension can give you the home you need without the cost and hassle of relocating.
The Benefits of Extending Your Home
1. Increased Living Space
This is the most immediate benefit. Whether you need a bigger kitchen, an extra bedroom, or a home office, extending allows you to create the room without compromising other areas of the house.
2. Avoiding the Cost of Moving
Moving comes with expenses—stamp duty, legal fees, estate agent costs, and removal services. In many cases, building an extension is more cost-effective than upsizing to a new home.
3. Boosting Property Value
A well-designed extension can increase your home’s value by up to 20%, especially if it adds desirable features like an open-plan kitchen or a second bathroom.
4. Personalised Design
You can tailor your extension to your lifestyle needs, from energy-efficient features to integrated storage or open-plan living.
Things to Consider Before Extending
1. Planning Permission
Some extensions fall under permitted development rights, but larger or more complex builds may require full permission. It’s essential to check your local authority’s requirements or speak with professionals offering planning support.
2. Budget and Costs
A single-storey extension typically costs between £1,200 and £2,500 per square metre, while double-storey builds can go higher. Always include a 10–15% contingency for unexpected issues.
3. Property Layout
Extensions need to enhance your layout, not just add floor space. Open-plan kitchen-diners or rear-facing lounge areas are popular options that improve flow and functionality.
4. Timeframe and Disruption
Most extensions take between 8 and 16 weeks to complete. Be prepared for noise, dust, and limited access to parts of your home during construction.
Is It Always the Best Option?
While extensions are beneficial, they’re not always the right solution. Consider the following:
- If your garden is small, a rear extension could reduce outdoor space too much.
- If your property has already been extended, planning permission may be harder to obtain.
- In some areas, high construction costs may outweigh the increase in property value.
Always weigh up the cost, potential return, and how long you plan to stay in the property.
Common Types of Home Extensions
Rear Extensions
Ideal for kitchen or dining area expansion, these are the most common and often fall within permitted development.
Side Extensions
Perfect for terraced or end-of-terrace properties with unused side paths.
Wraparound Extensions
Combining rear and side designs for larger, open spaces.
Double-Storey Extensions
These add both ground and upper floor space but require more planning and investment.
