SINGLE STOREY EXTENSIONS
Single storey house extensions are by far the most popular type; they can often be built without planning permission and the offer a fantastic opportunity to extend your shared living space without having an impact on sleeping or more private areas.
There are a few different types of single storey house extension, including side extensions, rear extensions, kitchen extensions, and orangeries. The right type for you depends on your home structure and what you would like to use your new extension for.
DO I NEED PLANNING PERMISSION FOR A SINGLE STOREY EXTENSION?
You don’t always need planning permission to build a single storey extension – you may be able to do this as a permitted development, depending on the build specifications, where you live, and whether or not your home has already had a permitted development added. If you have a loft conversion or a garage addition, you may not be able to build a house extension since the allowed permitted developments have already been used.
If you would like to build a particularly large house extension or build quite close to the boundaries, it is likely that you will need to apply for planning permission. You will also need to apply for consent if you would like to build using materials that differ from the existing house – this is a particularly popular approach for people living in period homes who would like a bright, contemporary extension that is true to its time rather than trying to emulate previous building materials and techniques.
If you would like more information about permitted developments and planning permission, please see our Planning Permission for Extensions page.
HOW MUCH DOES A SINGLE STOREY EXTENSION COST?
Building a single storey extension typically costs around £1,200-£1,500 per metre squared, plus VAT. Your costs depend on your build type, the size of your extension, the materials involved, and whether or not you need to apply for planning (which usually requires professional services such as architects). You will also need to pay for building regulation inspections and structural engineers, which can add around 10% onto the overall cost of your build.
