In most cases, you won’t need to apply for planning permission when building a DIY extension. This is because most extensions fall under permitted development rights. There are some exceptions to this, so it’s a good idea to consult with your local authority body first – they’ll be able to advise you if planning permission is necessary, and if so, can guide you through the application process.

Good news! All of our extension kits have received building controls pre-approval from a nationally accredited building control approvals agency. They’ve undergone rigorous testing, including detailed analysis and verification of the roof system using independently sourced structural calculations. They were also assessed for thermal performance and condensation risk analysis, which resulted in us being granted with System Approval.

One of the biggest advantages of DIY extensions is the price; our kits start at only £1,200 per square metre (with any style roof), which is tens of thousands less than the cost of a traditional extension.

As each Trade Price Warmer Living extension kit is made bespoke for the home it’s being fitted onto, the exact price can vary considerably – a large, more complex design will cost more than a simpler one, and vice versa.

Not at all – in fact, our kits are specifically designed to be beginner friendly! We provide clear, step-by-step instructions for what you need to do next, so you can have your extension up and ready for use in no time. We also include all you need to complete your build in one package, so you don’t need to worry about buying bricks or extra building materials.
