Waltham Forest is a London planning authority handling the full range of residential projects: rear and side extensions, loft conversions, basement extensions, outbuildings, prior approval applications, new build infill and change of use. Waltham Forest has 16 designated conservation areas and over 100 listed buildings, plus multiple Article 4 directions in force that remove permitted development rights in specific streets. Waltham Forest covers the Walthamstow, Leyton, Leytonstone and Chingford residential zones with the Epping Forest boundary shaping the borough's northern edge and raising the design bar for any work visible from the forest. The council's overall planning approval rate was 74% for year ending December 2025 per MHCLG Live Table P124, reported by the London Borough of Waltham Forest. If your property sits inside a conservation area, behind an Article 4 direction or on a listed building, assume you will need full planning permission rather than permitted development.
