Why was this refused?

Lack of justification for minor change status
Missing dimensions to verify footprint increase <5%
Harm to character from stone wall removal
Requirement for full planning process

The proposal was for a minor change application (MCH) to approved planning permission 24/91380/B, which permitted a detached garage and new vehicular access. The changes involved widening the garage and replacing the door with a single garage door.

Refusal Reasons

✗The application does not explain why the changes proposed are considered to be minor; or why they are being applied for.
✗It is not clear that the changes would not increase the net external footprint of the garage by more than 5% because no written external dimensions are provided.
✗The widening of the garage would result in the removal of part of the stone boundary wall on the northern boundary of the site. Stone boundary walls are common and distinctive features in the locality, which contribute to the character of the area. The removal of the wall at the site would be noticeable in the public domain and would constitute a new and potentially adverse impact upon the character and appearance of the area. This matter should therefore be considered through the planning application process and, consequently, the proposed minor change is not minor. Whilst the change to the garage door would itself be minor, it is not clear that this could be achieved without widening the building.
