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.
Policy detail lives in the Barking and Dagenham local plan and applications are submitted via the Barking and Dagenham planning portal.

Who to talk to about a Barking and Dagenham property
Constraint data tells you what applies. It does not draw a scheme, argue a case with Barking and Dagenham's planners, or inspect a building. For that this site points at two separately regulated practices — which one you need depends on the job in hand.
The architect's door: designing the scheme and getting it consented — drawings, the planning application and the building-regulations package.
- Residential design for extensions, lofts, basements and conversions
- Planning applications, pre-application advice and appeals
- Lawful development certificates
- Building-regulations and technical design drawings
- Conservation-area design and listed building consent applications
The chartered-surveyor door: professional judgement on condition, risk, party wall matters and leasehold process.
- Building surveys, RICS home surveys and defect diagnosis
- Party wall matters and awards
- Technical due diligence before a purchase
- Leasehold and major-works advisory (Section 20)
- Dilapidations and building pathology
Both practices are independent and separately regulated — Hampstead Chartered Surveyors & Building Consultancy is an RICS-regulated firm (Firm Reg. 923064); Hampstead Architecture and Planning are ARB-registered architects. We publish no fees for their work: each quotes directly for the job in front of them. Your enquiry goes to the practice you choose — we never pass your details to builders or other third parties.
