GS Renovation removes load-bearing walls throughout Eltham, from the bay-fronted 1930s semis off the high street to the interwar suburban houses set back on their generous SE9 plots. We open up ground floors safely, install the steel the engineer sizes and leave a level result signed off by building control.
In Eltham, a complete single opening typically costs £2,500 to £6,500 or more, including the engineer's calculations, the steel beam, propping and making good (indicative London ranges, MyBuilder and Checkatrade, 2026).

How the job runs
- Free site survey at your Eltham address and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with the Royal Borough of Greenwich building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped, the wall comes out and the beam is set on padstones.
- Building control inspects the steel before it is covered. We make good, and the completion certificate follows.
Load-bearing walls in Eltham's 1930s semis
Eltham's interwar semi-detached houses were built with a solid load-bearing wall between the front reception and the rear living room, carrying the floor joists and the wall above. Homeowners in SE9 nearly always want this spine opened up, but it is holding real weight, so we never touch it until a structural engineer has confirmed exactly what sits on top.
The engineer sizes a steel beam to carry the load once the masonry is gone, and specifies the padstones it bears onto at each end. On these 1930s plots the party wall with the attached neighbour often forms one bearing point, so the engineer designs that support carefully. We then prop the floors above, remove the wall in stages, seat the beam and make everything good.
Housing in Eltham
The valuation list shows roughly 14,360 homes in Eltham, of which 17% are pre-1919, 52% interwar and 30% post-1945, split 27% flats to 73% houses. Semi-detached houses make up 35% of homes here, and only the beam end on the shared wall of a semi in Eltham needs a party wall notice.
Building notice or full plans for an Eltham wall removal
Royal Greenwich building control says a building notice should only be used for simple work, and it gives a through room as its example. Taking out the wall between the two reception rooms of a 1930s Eltham semi is that job, so the quicker route can suit it. The trade off is that nothing is approved on paper before work starts. The structural engineer we appoint therefore finishes the calculations before the notice is lodged, and a copy stays on site for the inspector, because on this route the design is checked against the steel as built rather than ahead of it.
The route changes when the wall is one part of something bigger. Where new work goes over, or within three metres of, a public sewer, Royal Greenwich requires a full plans application, and behind an Eltham semi a new kitchen extension can sit right on that line. If the wall removal comes with a rear extension near the sewer, put both on the one full plans application. Splitting them, a notice for the wall now and plans for the extension later, leaves two sets of paperwork and two inspection sequences chasing one opening in the back of the house.
Building control sign-off across SE9
Taking out an internal load-bearing wall is structural work governed by the Building Regulations, not planning permission, so there is no planning application to make, though a listed home needs listed building consent for internal work. The support does need building control, and the Royal Borough of Greenwich, or a registered building control approver, inspects the beam, the padstones and the bearings before signing the job off.
Because these interwar semis share a party wall with the house next door, and one end of your new beam frequently bears into that shared wall, the Party Wall Act applies and you serve notice on the neighbour first, as building owner or through your surveyor; we give you the drawings it needs. We handle the engineer's calculations and the building control application, then complete the works as one accountable team with no loose ends.
How long the work takes from start to finish
A single opening in an SE9 semi is not a long job on site, but it is not a two-day one either. Allow time for the engineer's visit and calculations before anything starts, and for the building control application and any party wall notice, which run to their own timetable. Once we are in, protection and diverting services take the first day, propping and demolition the next, and the beam usually lands shortly after that.
Then it slows down deliberately. The bearings stay open until building control has seen them, the props stay in until the padstone mortar has gained strength, and only then is the steel encased and the opening plastered. Fresh plaster needs to dry before it is painted, longer in winter, and it wants a mist coat first. Rushing the decoration is the most common way a sound opening ends up looking patchy six months later. We give you a realistic sequence at the outset so you know which weeks are noisy and which are simply waiting.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal Eltham
What drives the cost of load-bearing wall removal in an Eltham home?
Scope drives the price of load-bearing wall removal in Eltham first, condition second and access third, inside £2,500 to £6,500 or more per opening (indicative). Scope is set by the regulations as much as the design: the work needs a Royal Borough of Greenwich building control inspection of the bearings before they are concealed. GS Renovation shows that element separately, and the SE9 survey establishes all three before a figure is committed.
Do I need planning permission to remove a load-bearing wall in my Eltham semi?
No. Removing an internal load-bearing wall is covered by the Building Regulations, not planning, so no planning application is needed, though a listed SE9 home needs listed building consent for internal work. You do need building control sign-off for the steel and, as the party wall is usually involved, a party wall notice, which you serve on your neighbour as building owner. We arrange the building control side and give you the drawings the notice needs.
How can I tell whether the wall I want out of my Eltham semi is carrying anything?
Look at the joists and at what stands directly above it. In a 1930s Eltham semi the first-floor joists usually span from the outside walls onto the central spine, and a bedroom partition often sits right on top. Lift a board upstairs to see which way the joists run, then check the loft for struts landing on the same line. The engineer confirms it, but those clues settle the question early.
Will the new beam hang below the ceiling in my Eltham house, or can it be hidden?
Either can work, and the joist direction decides which is easier. A downstand sits under the joists and shows as a boxed nib across the ceiling. A flush beam is set up within the floor depth with the joists hung off it, so the ceiling runs through level, but it needs more propping of the floor above and sometimes a heavier section. Choose before the engineer calculates, not after the steel is ordered.
Is an asbestos survey needed before a wall comes down in an Eltham interwar house?
Yes. VOA figures put 52% of Eltham homes in the interwar bracket, and any house of that age may hide asbestos somewhere. Textured ceiling coatings, old floor tiles, boarding round a boiler cupboard and the lining of a serving hatch are the usual places to look near a spine wall. The survey comes before strip-out, so any removal is programmed ahead of demolition day instead of being found halfway through it.
What happens to the floor where the old wall stood in an Eltham semi?
It leaves a strip that has to be rebuilt, not just covered. The boards on each side stop short of the old wall line and rarely meet at the same height, and under a suspended timber floor the sleeper wall below needs looking at. We pack, join or replace that section so the two rooms become one level surface, and the ceiling gets the same treatment where the old wall head was.
How soon after the building notice goes in can an Eltham wall come out?
Not before two days have passed, because Royal Greenwich building control needs two days notice before any work under a building notice starts. We use that gap for the jobs that come before demolition anyway: dust sheeting, isolating the circuits that run in the wall and setting out the props. The masonry stays untouched until the notice period has run, so the first inspection is never about work already done without notice.
Can a load-bearing wall come out of an Eltham flat the same way as in a house?
The structure works the same way but the permissions do not. 27% of homes in Eltham are flats, and in a flat the wall you want out may carry the floor of the flat above as well as your own ceiling. Check the lease, which will often require the freeholder's written licence before any structural alteration. Get that licence before paying for detailed calculations, because the freeholder's surveyor may ask for changes to the design.
Is the first hour of advice from Royal Greenwich building control really free of charge?
Yes. Royal Greenwich building control charges pre and post application advice by the hour, and the first hour carries no charge. For an Eltham wall removal that hour is best spent before the notice goes in, confirming the route and asking what the inspector will want to see at the bearings. After the first hour the time is charged, so arrive with the engineer's sketch, the wall position and photographs taken in the loft.
