5 Mistakes to Avoid When Building a Single Storey Extension
Building a single storey extension is an exciting way to add space to your home, enhance its functionality, and increase its overall value. However, without careful planning, what starts as an exciting project can quickly become a stressful and costly endeavour, leading to frustration instead of satisfaction.
From budgeting errors to planning oversights, there are several pitfalls that homeowners often encounter. To ensure a smooth and successful extension process, here are five common mistakes you should avoid to achieve the best results.
Some Common Mistakes to Avoid
Before you start building, it’s important to plan properly. Many homeowners make avoidable mistakes that can lead to delays, extra costs, or even legal issues. Here are the most common ones:
1. Not Checking the Rules & Permissions
Many people assume they can just start building, but there are rules to follow. Some extensions fall under Permitted Development Rights, while others need full planning permission. Things like height, how close you are to your neighbour’s house, and local council restrictions all matter.
Ignoring this can mean fines or even having to tear down your extension! The best thing to do is work with experienced extension builders who know the rules—especially if you need house extensions in South London.
2. Not Budgeting Properly
A lot of people only think about the basic construction costs, but there’s more to it than that. Depending on the size, materials, and where you live, the single storey extension cost can vary, this is why knowing the single storey extension cost matters. If you’re looking at house extensions in South West London, for example, prices might be different from other areas.
People often forget about:
1. Foundations and drainage
2. Insulation and heating
3. Plumbing and electrical work
The best way to avoid surprise costs? Get a clear, detailed quote from a trusted builder before starting.
3. Picking the Wrong Size & Layout
It’s easy to get carried away and build too big or too small. A single storey rear extension should feel like a natural part of your home, not something that sticks out awkwardly.
Think about:
1. Natural light: Roof windows and bi-fold doors can make the space feel bigger.
2. How it connects to your home: Will it flow nicely with your existing layout?
3. What you’ll use it for: Kitchen, office, extra living space?
A well-planned extension will be practical, comfortable, and a great investment.
4. Hiring the Wrong Builders
Not every builder has experience with extensions, and hiring the wrong one can lead to delays, poor work, and extra costs. A badly built extension can even make your home worth less instead of more!
To avoid problems:
1. Check reviews and ask for examples of their work.
2. Make sure they have experience in house extensions in South London.
3. Ask about their accreditations and insurance.
Good builders will save you money and stress in the long run!
5. Not Thinking About the Future
A single storey extension isn’t just about getting more space—it needs to work for you long-term. Many people forget about important things like:
1. Energy efficiency – Good insulation means lower bills.
2. Future-proofing – Will it still work for you in a few years?
3. Resale value – A well-designed extension adds value, but a bad one can turn buyers away.
Don’t just focus on adding space—make sure it makes your home better overall.
