ARE PLANNING PERMISSIONS REQUIRED FOR THE INSTALLATION OF HOUSE EXTENSIONS?
When it comes to planning permission, the answer depends on the size, location, and specifications of your house extension. As regulations within the home improvement industry continue to evolve, it’s important to stay informed about current planning requirements.
In many cases, you can build a rear house extension up to six metres without needing full planning permission—thanks to Permitted Development Rights. However, this can vary based on factors such as property type, extension height, and proximity to boundaries.
To ensure you’re fully compliant, we always recommend discussing your project with our team. We can provide guidance based on your specific plans and help you navigate any permissions required.

DO HOUSE EXTENSIONS ADD PROPERTY VALUE?
A house extension is one of the smartest investments for homeowners looking to expand their living space and add versatile new rooms. Whether you want a larger kitchen, an extra bedroom, a home office, or a playroom, a bespoke extension can be tailored to meet your family’s evolving needs over time.
Not only do house extensions provide more space, but they also boost your property’s overall value. While the exact increase depends on your local market’s ‘ceiling value’ and the specifics of your project, most extensions deliver a strong return on investment by enhancing your home’s functionality and appeal.
