Some home extensions are classed as permitted development, which means they may not require planning permission. However, this depends on the size, design and location of the extension, as well as the type of property.
For example, factors such as whether the work is single storey or two storey, how far it extends from the original house and the materials used can all affect whether planning permission is required. If your home is in a conservation area or has already been altered, further rules may apply.
We can guide you through the planning side of your extension project and help you understand whether your proposed house extension falls under permitted development or whether you will require planning permission.
