Minor material amendments are applications that seek approval for minor changes on a previously approved application.
At present there is no certified definition of what constitutes 'minor' or 'material' changes, as this depends wholly on the specific context of the application, and will take into account things like size or whether any previous planning permission has been granted.
An application for minor material changes is usually submitted in order to determine whether the proposed changes are minor or not. If it is decided that the changes are not minor then the application will be refused.
Guidelines for assessment
To be considered as minor, the proposed changes should not differ drastically from the approved plans, but can include small changes - such as to scale, height or footprint - that do not alter its style or total area.
Minor material amendments do not usually include:
- new windows, openings or enlargements which would result in an unacceptable loss of privacy to neighbours
- a change to external materials which would harm the appearance or quality of a development
- a change to the external look of a development which would look significantly different to approved plans
- a change which would lead to a big increase in traffic or parking
If you are in any doubt about where a proposed change is likely to be minor material or not then, to avoid delays, we recommend applying for a revised full application.
