Structural Alterations Barking and Dagenham

GS Renovation carries out structural alterations throughout Barking and Dagenham, from Chadwell Heath through Becontree to the streets around Barking Park. In the interwar and later houses of IG11, RM8, RM9 and RM10, we form new openings, replace tired joists, underpin and install supported openings that last, drawing on our founder's 30+ years.

In Barking and Dagenham, a simple new opening starts from £1,500, and underpinning a single elevation typically costs £6,000 to £21,000 (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Barking and Dagenham.

How the job runs

1. Free site survey at your Barking and Dagenham address and an itemised quote.
2. The engineer we appoint designs the work, and it is registered with Barking and Dagenham Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props and any trial holes first, then the opening, joists or underpinning in the engineer's sequence.
4. Building control inspects each stage before it is covered, then issues the completion certificate.

Structural alterations for Barking and Dagenham homes

The borough's interwar houses lend themselves to structural change, whether that is a wide opening between kitchen and dining room, a new opening in the flank wall of an end-of-terrace house, or a bigger opening onto the garden. Every alteration starts with a structural engineer's calculations, so the steel, the lintels and the bearings are matched to the actual loads in your particular house.

Older Becontree and Dagenham properties can also need remedial structural work rather than reconfiguration. We replace decayed or undersized floor joists, form supported openings with correctly sized beams on padstones, and underpin where movement or a shallow original footing calls for it, always to an engineer's design and with staged, well-propped working throughout.

Adding a storey or taking something down in Barking and Dagenham

On 18 January 2022 Barking and Dagenham Council confirmed an Article 4 direction covering the whole borough except designated industrial land, removing the permitted development right to add storeys. It came into force from 22 February 2022, so raising a house or a block of flats by a storey needs planning permission, whatever the national rules allow elsewhere. Structurally, an extra storey means walls and foundations carrying loads they were never designed for. The structural engineer we appoint therefore checks the footings and the walls before the planning drawings are finalised, because an approved scheme that turns out to need underpinning has been designed in the wrong order.

The second rule catches alterations that begin by taking something down. Barking and Dagenham says it is an offence to begin demolition without giving notice, and that at least six weeks notice must be given. If a structural alteration starts with demolishing a rear addition, a garage or an outbuilding before rebuilding, ask Be First Building Control early whether notice applies, and put the six weeks into the programme ahead of the first skip. That period is also the time to commission the drainage survey and trial holes that the new foundations will need.

Engineered and certified across IG11 and RM10

Structural alterations are notifiable under the Building Regulations, so Barking and Dagenham Council's building control inspects the works at the key stages, including underpinning excavations before they are filled and beams before they are cased in. We coordinate every inspection and hand you the completion certificate, which lenders and buyers will expect to see for this kind of work.

Because the borough's houses share a party wall with the house next door, alterations such as underpinning, cutting into the shared wall or bearing a new beam onto it are notifiable under the Party Wall Act. We identify what applies at the survey stage; you serve the correct notices on your neighbour as building owner, and we give you the drawings and programme they need so the process moves without hold-ups.
