Why it was refused

  1. The alteration proposed to the form of the roof of the approved alterations would cause a materially different impact to that of the original scheme as approved under 2026/00020/FUL. This is considered to go beyond what the planning authority consider to be a non-material amendment and the proposal therefore fails the tests set out in the Welsh Government Guidance "Approving Non-Material Amendments to Existing Planning Permission" and planning permission is required.

From the council's decision notice.
