Will I need to get planning permission for a rear home extension?

Many authorities in the United Kingdom consider rear extensions to be Permitted Development. You don't need approval if your proposed rear expansion layout complies with all Permitted Development laws and regulations set by the council.

If your property plan does not comply with Permitted Development requirements then you must submit an application for approval. Even if you can do it yourself, it may not always be effective. Mostly because you'll need accurate designs for your rear extension plan, and it's best to get professional help from an experienced and qualified builder.

If your home falls under the following, you will need to get planning permission:

- If your home is a listed structure or is located in a conservation area 

- The proposed rear expansion will be more than half the width of the house. 

- The height of the single-story back addition cannot exceed 4 metres. 

- The rear extension's new roof should not be taller than the present roof. 

- The planned extension shall be at least 3 metres tall and within 2 metres of the property line. 

- If the rear extension contains chimneys, balconies, verandas, or a microwave antenna. Any alterations to the roof's original design.

How much does a rear home extension cost?

The expense of a rear extension is not set at a fixed price. You must first understand your requirements, after which the cost may be calculated. The cost of a rear expansion is determined by a variety of factors, including labour costs, materials, and other planning permission application charges. 

High-quality materials are costly, but they are worthwhile if you want your rear extension to look good and last a long time. They do, in fact, come at a reasonable price. Even though it is costly, they do add to the value of your property.
