Planning in Barking and Dagenham — the detail
Barking and Dagenham is an outer-east-London borough dominated by the vast interwar Becontree Estate — one of the largest council-built estates in the world — alongside the historic core of Barking around its abbey ruins and town centre, and the Thames-side at Riverside. Its four conservation areas in the national dataset are the Abbey and Barking Town Centre, the Abbey Road and Riverside area, Dagenham Village and the Chadwell Heath anti-aircraft gun site.
The borough controls HMO conversions through a borough-wide Article 4 direction, so converting a house to a small HMO needs planning permission everywhere. It has also made Article 4 directions removing the permitted development right to add an extra storey in specific areas — recorded as the Dagenham Village and Lymington upward-extension directions — and a direction controlling certain commercial-to-residential changes outside industrial land. Householder schemes are guided by the council's Residential Extensions and Alterations SPD.
Outside the conservation areas, much of the borough's suburban stock keeps permitted development rights for rear extensions, side extensions and loft conversions. The address-level check separates a permitted-development project from a full application in a conservation area, and confirms whether the HMO or an upward-extension Article 4 direction applies.
