GS Renovation creates open-plan spaces across East Ham, where the Victorian and Edwardian terraces of E6 were built as rows of small, separate rooms. We turn the traditional front-and-rear reception layout into one bright space, engineered and signed off properly.
In East Ham, a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in East Ham: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs
- Free site survey at your East Ham address, covering the walls, services and floor levels, and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Newham Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
- Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.
Open-plan conversions in East Ham terraces
The terraces of East Ham were designed as a series of small, separate rooms: a bay-fronted parlour, a back reception, a narrow closet wing and a galley kitchen. Modern families want these opened up, whether a simple knock-through between the two receptions, a full kitchen-diner reaching into the side return, or a broken-plan layout with a Crittall-style divider keeping some separation while sharing the light.
Between parlour and back reception runs the spine wall carrying the floor above, which makes any opening there a structural decision. An engineer sizes the steel to that load and sets a padstone under each end. We prop the floor above, take the wall out in stages, set the steel and only then remove the temporary supports.
Housing in East Ham
The Council Tax list puts East Ham at about 15,490 homes, 41% flats against 59% houses; 64% went up before 1919, 6% between the wars and 30% after 1945. Opening up a terrace in East Ham usually lands one beam end on the party wall, and 57% of homes here are terraced.
Daylight and construction limits on East Ham open-plan layouts
In East Ham 57% of homes are terraced houses and only 1% are semi-detached or detached, so few houses here have a side wall that can take windows. When two rooms become one in a mid-terrace, the new space is lit from the front bay and the rear windows only, and the middle of a deep room can end up darker than either room was before. We look at that before the steel is designed. A glazed rear opening, a rooflight over a side return, or internal glazing between the stair hall and the new room can each be settled at the same time as the beam, since moving a rooflight later means reopening a finished ceiling.
The 14% of East Ham homes built in 2000 or later need a different survey. Newer houses and flats are more likely to have concrete ground floors, blockwork partitions and floor joists designed to span between particular walls, and the original building control drawings may still exist with the developer or the management company. Ask for them before the engineer visits, because they show which walls were intended to carry load. Engineered timber joists in newer floors can only be cut or drilled where the manufacturer allows, unlike solid Victorian joists, which limits any plan to hide a new beam within the ceiling depth.
Consents and party wall in E6
Joining two E6 receptions is a Building Regulations job with no planning application, and Newham Council's building control, or a registered building control approver, reads the engineer's calculations and sees the bearings before sign-off. You would only involve the planning department for exterior work within a conservation area, though a listed building needs listed building consent for internal work too.
With 57% of East Ham homes terraced, the steel usually seats into the wall joined to next door, so you serve Party Wall Act notice first (or your surveyor does). We coordinate the whole conversion under one roof: engineer's design, propping and staged demolition, the steel and padstones, building control inspections, then plastering and making good, so your open-plan space is finished and signed off.

FAQ
Frequently Asked Questions about Open-Plan Conversions East Ham
How much should open-plan conversion in East Ham cost?
The cost of open-plan conversion in East Ham is typically £3,000 to £8,000 or more (indicative), and the E6 survey decides where in that range your job lands. The biggest mover is what the survey finds: the ceiling height decides whether the beam sits flush or drops below it. GS Renovation shows the Newham Council building control fee on its own line, and the written figure follows within days of the visit.
Can I knock through both reception rooms in my East Ham terrace?
Usually yes, but that wall holds up the middle of the house, so an engineer sizes the steel for what it carries before anything is cut. The beam bears onto padstones, is signed off by Newham building control, and because it bears into the party wall, you serve a party wall notice as building owner. We handle the building work and building control, and give you the drawings the notice needs.
Is joining the kitchen to the back room better than joining the receptions in an East Ham terrace?
For most families, yes. East Ham terraces were laid out as a bay-fronted parlour, a back reception, a narrow closet wing and a galley kitchen, and it is the kitchen end that feels cramped. Opening the back reception into the closet wing gives a kitchen-diner facing the garden, while the front room stays a separate, quieter space.
Does an East Ham upstairs flat need a fire plan before going open plan?
Yes. Flats make up 41% of East Ham dwellings, many of them floors of converted terraces. In a flat the internal hall protects your route to the front door, and opening the kitchen or lounge onto it alters that route, so Part B requires the escape approach to be agreed with building control. The freeholder also needs to consent.
Will the heating cope once an East Ham terrace is opened up?
Not always without changes. One large room with solid Victorian walls and a big rear opening loses heat faster than two small ones. The radiator from the removed wall has to go somewhere, and the heat needed for the whole space is recalculated so a larger radiator or extra panel is piped in before plastering.
Where does the steel go when an East Ham kitchen opens into the closet wing?
Often in two places. Opening the back reception into the side of the closet wing can need one beam across the old rear wall and a second along the wing wall, meeting on a post or pier. The engineer sets out that junction, and the steel goes in before any kitchen first fix begins.
How much daylight reaches the middle of an opened-up East Ham terrace?
Less than the floor plan suggests, because the only windows are at the two ends. Terraced houses make up 57% of East Ham homes, and a bay at the front and a window facing the garden are all the glazing a through room gets. Stand in the room at midday in winter with the doors open before committing. If the middle stays gloomy, a wider rear opening or a glazed door onto the hall adds more than a paler paint finish will.
Are the walls in a post-2000 East Ham home load-bearing?
Some are and some are not, and the original drawings answer it faster than guesswork. 14% of East Ham homes were built in 2000 or later, and houses of that age were approved against drawings that show which walls support floors and which are partitions. Ask the developer, the management company or the previous owner for them. The structural engineer we appoint still confirms on site, since later alterations are not always recorded.
Does the build era of an East Ham home change the open-plan method?
Yes, and East Ham splits sharply by era: 64% of homes were built before 1919 and 30% after 1945. The older houses have solid brick spine walls and timber floors, so openings bear onto old masonry through padstones. Post-war and newer homes can have concrete floors, blockwork and engineered joists, so fixings, bearings and the way pipes and cables are rerouted all differ. The survey starts by dating the house rather than assuming its construction.
