Retaining walls
If you are building a wall which is retaining land over 1.5m in height you will need to submit an application. This applies to new retaining walls or extending an existing one.
A retaining wall is a wall which supports earth or other similar material on one side. This means that the top level will be at least 1.5m higher on one side of the wall than the other.
How to apply
You need to submit a scaled location plan which must show the position of the wall and any adjoining boundaries or buildings. You should also include details of the construction and materials to be used and all calculations.
You should submit the retaining walls application form along with plans and documents. There is no charge for this application.
You can apply by:
- sending your completed application to bcon@swansea.gov.uk.
- contacting us on 01792 635636 where a form can be filled in on your behalf.
- posting the completed application to Swansea Building Control or bring it to the Contact Centre in the Civic Centre.
Planning permission
Remember you may also need planning permission for the work. If so you will need to apply and be given permission before you start work. Application forms and information are available on our Planning pages.
