In the UK, whether a home extension needs planning permission depends on its size, location and how it affects the surrounding area. Many extensions fall under permitted development rights, meaning they can be built without planning approval, as long as they meet strict rules.
Planning permission is usually not required for rear extensions on houses.
They should stay within permitted development limits. For example, a single-storey rear extension can extend up to four metres from a detached house or three metres from a semi-detached or terraced house. Height restrictions also apply, and the extension must not cover more than half of the original garden area. Materials should be similar in appearance to the existing property. If you’re not using your garage to store a car, you can create a new room.
However, planning permission is required in several situations
If your property is a flat or maisonette, permitted development rights do not apply. Extensions that exceed size limits, are two storeys, or significantly alter the front of the house will usually need approval. Homes in conservation areas, Areas of Outstanding Natural Beauty, national parks or listed buildings are subject to additional restrictions, and planning consent is almost always necessary. If this is an area you are interested in working in, you can apply for one of the many builders merchants vacancies. You can find builders merchants vacancies online.
Always check with the relevant authorities
Before starting work, it’s wise to check with your local planning authority. This will offer peace of mind and avoid issues when selling your home.
