Do I Need Residential Planning Permission?
Use the Gabriel Quick Check Planning Permission Tool™ to find out!
The information provided below is a list of those extensions which, in most cases, may be added to a dwelling without the need for planning permission from the Council as the Local Planning Authority. However, the complexities of the planning system are such that it is not possible to provide a definitive list of the works that may be undertaken to a dwelling without the benefit of planning permission.
The tool below will provide you with an idea of whether or not permission is required for your proposal.
You are invited to read the information, to tick the relevant boxes and provide your details. Upon submission of this information, we will assess your proposal and contact you within two working days.
Permitted Development Planning Questions
General Permitted Development Order (2015)
Schedule 2, Part 1 – Development within the curtilage of a dwellinghouse
Class A – the enlargement, improvement or other alteration of a dwellinghouse
Class B – Additions to the roof of a dwellinghouse

Class D – The erection of a porch outside any door of the dwellinghouse
Class E – The erection of an outbuilding or swimming pool in the garden of the dwellinghouse
Class F – Hardstanding
We strongly advise that in the event that an extension you are proposing does fall within one of the above classes of development and does not require planning permission that you apply for a Certificate of Lawfulness for the proposal. This is a legal determination as to the need for planning permission for a proposed extension.
Please contact us for further information. We would be pleased to explain.
The interaction between the classes can be complex. If you are considering an extension to your dwelling which would involve more than one of the above classes of development or more than one element of one of the classes, and planning permission would be required for only part of the overall proposal, please contact us.
In addition to the above classes of development that may be added to a dwelling as permitted development, it is possible to extend a dwelling with a single storey rear extension by 6m for a terraced or semi- detached dwelling, or by 8m for a detached dwelling without the need for formal planning permission from the council. The process is one whereby an application needs to be submitted to the Council under what is known as the Prior Approval Procedure. This involves a relatively simple submission whereby the neighbours are consulted about the application and any comments made are considered in the determination of the application. We would be happy to provide an explanation.
Furthermore, additional floor or floors may be added to a dwelling without the need for formal planning permission from the council, under another Prior Approval Procedure. As with the larger householder extensions above, this involves a relatively simple submission whereby the neighbours are consulted about the application and any comments made are considered in the determination of the application. Once again, please contact us and we would be happy to provide an explanation.
