Do I need planning permission for a house extension?
Deciding to extend your home is an exciting step toward creating more space and enhancing your property’s value. However, a common question for homeowners in the UK is whether planning permission is required for a house extension. Understanding the regulations can save time, money, and potential legal issues. HM Builders Glossop, the trusted #1 name in Glossop, Derbyshire, serving Tameside, Derbyshire and the High Peak, Stockport, Cheshire, and Greater Manchester, is here to guide you through the process. As a fully licensed and insured company, we serve both home and business owners throughout the region with expertise and reliability.
In the UK, many house extensions fall under Permitted Development (PD) rights, meaning you may not need planning permission, provided your project meets specific criteria. These rights apply to most single-storey and some two-storey extensions, but rules vary depending on your property type, location, and the scale of the extension. For instance, if your home is in a Conservation Area, National Park, or Area of Outstanding Natural Beauty, stricter regulations often apply, and planning permission is more likely to be required. Similarly, listed buildings always need consent for any alterations, including extensions.
For a single-storey rear extension, PD rights typically allow you to extend up to 3 metres for terraced or semi-detached houses, or 4 metres for detached houses, without planning permission. However, under the Neighbour Consultation Scheme, extensions between 3 and 6 metres (for semi-detached/terraced) or 4 and 8 metres (for detached) require notifying your local planning authority, who will consult your neighbours. If no objections are raised, you can proceed without formal permission. Two-storey extensions are more complex, with restrictions on height, proximity to boundaries, and design compatibility with the existing structure. Side extensions and those covering more than half the original garden area often require planning permission.
Other factors to consider include Building Regulations, which apply to nearly all extensions, regardless of planning permission. These ensure your extension is safe, energy-efficient, and structurally sound. You’ll also need to check for Party Wall Agreements if the extension affects a shared wall with a neighbour. HM Builders Glossop has extensive experience navigating these requirements, ensuring your project complies with all regulations while meeting your vision.
If your extension exceeds PD limits or your property has specific restrictions, you’ll need to apply for planning permission through your local council. This involves submitting detailed plans, which HM Builders Glossop can help prepare. The process typically takes 8-12 weeks, and costs vary by council. Early consultation with professionals can prevent costly delays or rejections.
