Conservation areas in Harrow typically remove several permitted development freedoms. For a dropped kerb, the Larger Home Extension route and some external alterations do not apply, so a full householder application is usually required. Planning officers at Harrow Council assess conservation area proposals against the specific character appraisal for the street.
