Across Lambeth: what refusals were about
Of the 120 refusals whose decision notices we read, the share that gave a reason about each.
- Design and character of the area 63% That the work suits the house and the street: its size, its shape, its roof and its materials.
- Neighbours' amenity 31% 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.
- Heritage assets 20% That the work does no harm to the character or appearance of a conservation area, or to a listed building, its setting or what makes it special. The council gives that great weight, and any harm needs clear justification.
Lambeth as a whole granted a comparable share across 1,733 decisions. See the whole council.
