Across Croydon: what refusals were about
Of the 121 refusals whose decision notices we read, the share that gave a reason about each.
- Design and character of the area 58% That the work suits the house and the street: its size, its shape, its roof and its materials.
- Neighbours' amenity 50% That the neighbours keep reasonable light, outlook and privacy: no wall that looms over them, and no window that overlooks their home or garden more than the council judges acceptable.
- Insufficient information 31% Drawings and details enough to judge the work: what the council's own list of requirements asks for, and anything its policies need shown.
Croydon as a whole granted a comparable share across 1,334 decisions. See the whole council.
