Larger Extensions

Here is an update!

Notification of Larger Extensions – the rules governing this have been extended to 30th May 2019. Should you already have prior approval you now have until this date to get the extension fully completed. New applicants will of course have until this date to complete the work. This completion date rule is exclusive to this type of application as other planning applications have 3 years to START the work. You can read about the rules and procedures on the Planning Portal website on the following link or contact ConstructAid for further advice:

Here are the Guidance Notes published by the Planning Portal regarding the larger home extensions legislation recently passed and sets out in detail what is required to obtain approval and links for further information. This new law allows a maximum 6 metre extension on a terraced or semi-detached property and 8 metres on a detached property, although this law is for a 3 year period only. Any further advice can be obtained from ConstructAid as in our view, plans will still be required for Building Control and the Builder/Contractor. There is a process to obtaining approval from the Planning Department for the development as set out in the Guidance Notes and approval is not automatically given. For example, it is important to bear in mind that if a neighbour objects then the Planning Department will be required to decide if they are to give permission to the proposal or not! The Guidance Notes also point out that if the Council do not respond within a certain time period, permission is automatically granted. Watch this space for comments by Admin if there are any problems in the implementation of this law!

  1. Update! Have started to make the first applications under the new Larger Extension process. I will report back on our experiences and if we encounter any problems with the procedure.

  2. ConstructAid have now had an opportunity in implementing the new Notification of Larger Extension regulations, and we must say they have proved to be more problematic than we had anticipated. The legislation is, in effect, quite different from any current planning regulations and consequently it has led to some problems with interpretation of the law. One of the most important points to remember is that in submitting a Notification application (which does not involve payment of a planning fee), it is still necessary to apply for a Lawful Development Certificate for a proposed use. This would prove that the extension is lawful in relation to the other parts of the legislation that are not covered under the Notification application.

    Also it is to be noted that if, after obtaining a satisfaction Notification approval from the Planning Authority, it is decided that, for example, a pitched roof is required instead of a flat roof that has been approved, it is most important that no work is carried out until a new Notification application is approved by the Council. The Notification is only applicable to work that has not been started so in starting work, this procedure would not be possible under the Notification of Larger Extension legislation and a planning application would have to be submitted. As the larger extension would, in most circumstances, be larger than that permitted under the Local Development Plan, there would be a strong likelihood that planning permission would not be granted for the proposal. More thoughts on this subject will be published but should you require any information on this or any other development, please contact ConstructAid via our website
