Why it was refused

The City Council does not agree that the amendments are sufficiently minor in terms of the materials, scale and impact (both individually and cumulatively) in planning terms, having regard to the overall scope of the previously approved development, so as to constitute non material amendments to the planning permission dated 6th March (RN:23/06009/FULL).

From the council's decision notice.
