Do you need planning permission for a side extension? 

Most side extensions are built without planning permission and under permitted development. There are rules you must follow to for your project to be under permitted development. For example: 

  • Must be single storey 
  • Cannot exceed 4m  
  • The width cannot exceed more than half of the original house.  
  • The materials used must match the exterior of the existing house.  
  • If the extension is within two metres of a boundary (which a side return extension usually is) maximum eaves height cannot exceed 3m. 

How much would it cost? 

An average side extension design can cost anywhere between £20,000 – £50,000. However, this depends on the size, finish and where you live. Also, internal work such as adding a kitchen or glazed doors will affect the final price. 

The benefits of a side extension –  

  • Adds value if done correctly. If you are just looking to do a single storey, the value can increase by 10%.  
  • Helps you maximise space at the side of your house. 
  • You won’t be losing any land at the rear of your property.  
  • Adds additional space to your home 

Building regulations –  

Finally, your project will need to comply with building regulations which cover everything from structural stability of the walls to fire safety, electrics, and drainage. These rules and regulations ensure that your extension meets national minimum standards of safety and workmanship. The approval of your local authority building control department is always required whether you require planning permission or not.

When we talk about British homes, there are mainly three types of extensions: Side return extension, wrap around extension and the rear extension. However, we are going to focus on the most common, the single-storey rear extension in this article. 

A rear extension goes across the full width of the house. It goes out towards the garden. Edwardian and Victorian houses have a cellular feel. So, adding a rear extension can link together two areas to provide you with more open space for your family. Furthermore, if your house doesn’t get much daylight, adding bifolding doors or large windows to the extension can brighten the place up.  

Will you need planning permission?  

Whether you need planning permission or you can develop under permitted development rights. Single storey rear extension does require LDC (Lawful Development Certificate). You need to apply for this certificate to your local authority. Basically, it indicates that the extension you are building met permitted development requirements and you don’t need planning permission. It will cost you around £103 which is less than the planning fee. 

Will a single storey rear extension add value to your home?  

Well, how much value it’s going to add depends on the extension and space you want to create. Any extension adds value to the property that’s for sure. But you have to create a balance. You have to make sure that the extension is cost-effective and also adds value to your house.
