Why it was refused

  1. The proposed amendments would result in a materially different scheme to that approved under planning permission 25/0262/HH, due to the introduction of an irregular and unbalanced roof form with an off-centre ridge and unequal roof pitches. These changes would materially diminish the design quality of the approved development and result in a visually detrimental form of development, notwithstanding its limited visibility from the public streetscene. The proposal therefore fails to meet test (a)(ii) of the Welsh Government guidance on non-material amendments and is contrary to the principles of good design supported by Policy SP6 of the Local Development Plan. As such, the proposal cannot be considered a non-material amendment under Section 96A of the Town and Country Planning Act 1990 (as amended).

From the council's decision notice.
