Extensions are one of the most popular additions you can make to a home. An extension can add new space to your home, while giving it a unique, stylish look. Plus, research suggests that a quality extension can add around 10 per cent to the value of your house. Read on for a guide to home extension in 2022.

Check the law

To begin with, you’ll need to check to see if you require planning permission. You can build an extension under ‘permitted development’ rules as long as it doesn’t exceed 50 per cent of the area of land your house sits on. As such, you should work out whether you’ll be exceeding permitted development, or whether you’ll find yourself within the rules. If you don’t exceed 50 per cent of the area of land your house sits on, you can avoid the hassle of securing planning permission.


Once you’ve analysed the law and your potential project, you need to begin planning. To start this process, you’ll have to find an architect who can turn your dreams into reality. Finding the right architect can be difficult, but by following customer reviews and by seeking recommendations you should be able to find someone trustworthy. After that, you’ll need to consider how you’ll design the interior, before turning your attention to construction.


Budgeting carefully is crucial for your extension too. Having to prematurely end work on your extension after running out of cash is a nightmare scenario. It’s easy to get carried away when designing your extension, but it’s best to be cautious. Forecast your budget pessimistically and always ensure that you have contingency savings that can allow you to finish off the project if it runs over budget. All this is achieved by factoring in the cost of construction, architect fees, the materials and the labour required to put it all together.

DIY or a professional

The final question to ask yourself is whether you’ll build the extension or whether you’ll hire professionals to carry out the work. Construction workers will cost you much more, but it can often be worth it to enjoy the knowledge that your extension will be built quickly and efficiently. However, if you’re competent at DIY tasks and have the time to take on the project yourself, you could consider building it without help.

Once you’ve completed your planning and worked out your strategy for your extension, you’re almost set to begin construction. Just ensure that you take out home renovation insurance beforehand to give yourself peace of mind that you’ll avoid any unwanted surprises.
