Planning Permission for Your Cheshire Extension

Extensions come in many shapes and sizes. Most single storey extensions don’t usually require planning permission. If you’re looking to extend your property and want instant planning permission advice, contact the Crystal Living team today.

Do you need planning permission for home extensions?

You won’t need planning permission for your home extension if you meet the following parameters.

  • The extension covers no more than half the original garden area
  • It is not situated forward of the main property
  • It is not higher than the highest part of the roof
  • For single storey extensions, it must not extend from the house by more than 4 metres for detached properties and 3 metres for other styles of property
  • A single storey extension is not higher than 4 metres
  • 2 storey extensions do not reach to closer than 7 metres from the rear boundary
  • The brickwork/materials used match the existing property
  • It does not include verandas or balconies
  • Any upper floor, side windows are obscure-glazed

Local authority planning permission

When extending your property, the need for planning permission often depends on the local authority. At Crystal Living we work across Manchester, Cheshire East, Cheshire West and Chester. For local information on planning permission regulations visit the government’s planning portal or get in touch with us. The need for planning permission also varies for different types of property. If you live in a house and your extension meets the above criteria, you probably won’t need planning permission. However, if you live in a flat or maisonette or a designated property, you will need to obtain planning permission to build an extension.

Building regulations

Complying with building regulations is separate from planning permission. Building regulations ensure that any work carried out on your home is of a good standard and does not breach health and safety requirements. As a completed extension is considered part of the main house, it is therefore subject to the same building regulations.

When building an extension, you will need to prove that it is as energy efficient as the rest of the house. If your extension is built on or within 3 metres of a public sewer, then you will need permission from the local water board. Once the work is completed your local building control officer will inspect the extension to ensure that no damage has been done. When building an extension, you must comply with building regulations for:

  • Internal and external walls
  • Plumbing and drainage
  • Lighting and electrics
  • Roofing
  • Foundations and walls below ground level
  • Flooring
  • Ventilation
  • Structural opening
  • Energy efficiency
