Why it was refused

  1. By virtue of its height, scale, bulk and massing, the proposed development would harm the external appearance of the building. Prior approval is therefore refused under Condition Class AA.2.(1)(e), Part 20, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).

From the council's decision notice.
