GS Renovation removes load-bearing walls across Southwark, from the post-war blocks and estate flats that make up most of the borough to the Georgian houses around Camberwell and Dulwich, the Victorian terraces of Peckham and the warehouse conversions of Bermondsey. We open up homes safely and leave them properly supported.
In Southwark, 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). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Southwark.

How the job runs
- Free site survey at your Southwark address and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Southwark Council 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.
Taking out walls in Southwark's period homes
In Southwark's Georgian and Victorian houses, the internal walls that separate the front and rear reception rooms are usually solid masonry carrying the floors and, in narrow SE22 and SE21 houses, part of the roof load above. We never guess at this. Every job starts with a structural engineer establishing exactly what the wall holds, so the steel we install is sized to the real loads rather than a rule of thumb.
The engineer specifies an RSJ or twin steels that bear onto padstones spread across the remaining masonry at each end. We prop the structure temporarily, take the wall down in safe stages, lift the beam into place and transfer the load before removing the props. In many Peckham and Camberwell terraces the wall ties into the shared party wall, so the bearing detail is designed to suit that older brickwork.
Housing in Southwark
By the valuation list's count, Southwark holds about 149,990 homes, 19% houses and 81% flats; by age, 25% were built before 1919, 7% between the wars and 64% since 1945. Since most homes here are flats, a wall in a flat in Southwark may carry the floors above, so the freeholder agrees first.
Taking out a wall in a listed Southwark house
In a listed house in Southwark, removing an internal load-bearing wall needs listed building consent as well as building regulations approval, because the plan form of the rooms is part of what the listing protects. Southwark's final fees and charges schedule sets a pre-application fee for householder listed building development, extensions or internal alterations. For a wall removal that service is worth using early, with the engineer's sketch of the opening in hand. It tells you whether the idea is acceptable in principle before paying for full structural calculations and a heritage statement, and whether a smaller opening would be.
The designs that tend to be easier to justify are the ones that leave evidence of the original layout in the finished room. Short nibs of wall at each side, and a downstand where the wall used to be, keep the line of the two rooms readable and give the steel a bearing that need not be cut into the party wall. A flush beam with the wall erased completely is harder to argue for. Where cornices or skirtings run into the wall, record them before any work and return them at the new opening rather than cutting them back.
Party wall and building control in Southwark
Because Southwark's terraced and semi-detached period homes share a party wall with next door, cutting a beam pocket into that wall to carry a new steel is notifiable under the Party Wall Act. You serve the party wall notice as building owner (or your surveyor does); we give you the drawings and programme it needs and build to any award. Where surveyors are appointed, they usually record the condition of the neighbour's side first. In Bermondsey's leasehold warehouse conversions the picture differs: many partitions are non-structural, but altering anything structural needs the freeholder's licence to alter and coordination with the managing agent.
Removing an internal load-bearing wall is a Building Regulations matter, not planning, so Southwark Council's building control inspects and signs off the completed steelwork. External changes may need planning permission, particularly in the borough's many conservation areas and always on a flat, and a listed building needs listed building consent for internal structural work too. We coordinate the engineer's calculations, the drawings for your party wall notice or freeholder consent, the propping, the steel and the building control sign-off as one accountable package.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal Southwark
Can you quote load-bearing wall removal for an SE1 property over the phone?
GS Renovation will not give a real quotation for load-bearing wall removal in Southwark over the phone, only the range, £2,500 to £6,500 or more per opening (indicative). On 07472 424 226 we can explain what moves the cost and whether the job needs a Southwark Council building control inspection of the bearings before they are concealed, but the SE1 property has to be seen first. Builders who quote blind across Southwark revise the figure once the floor or walls are opened.
Does the variety of housing across Southwark affect wall removal?
It determines the method entirely. Southwark ranges from Georgian and Victorian terraces to post war estates and recent apartment buildings, and what a wall is doing differs completely between them. In a framed block an internal wall may carry nothing, while in a panel built property the same wall is the structure. The construction is established before anything is designed.
Can a leaseholder in a Southwark block remove an internal wall?
Only with the landlord's written consent, and in some blocks not at all. A Southwark lease will normally reserve structural alteration to the freeholder, and where the block is of concrete panel construction the internal walls may be structural elements that cannot be altered. The lease and the building's construction are both checked before a design is commissioned rather than afterwards.
What is involved in opening up a Southwark terraced house?
A beam sized for the floor above, bearing into the walls at each side. In your Southwark terrace the wall between the front and rear rooms usually carries the joists above and sometimes a partition upstairs, so the engineer designs for both. The bearings land in the party walls, which brings the work under the Party Wall etc. Act and requires notice from the owner.
What is worth checking before buying a Southwark property to alter?
Whether the alteration is possible at all. Establishing the construction, the lease terms where it is leasehold, and whether previous work was approved will answer more than any assumption about what similar properties have done. Your Southwark flat in a framed block and one in a panel built block look the same and offer very different possibilities. That check is cheap before exchange and expensive afterwards.
How is a Southwark property left at the end of each day?
Safe, secured and reasonably clean. On a Southwark job that means propping is checked before anyone leaves, debris is cleared rather than stacked in the working room, any opening to the outside is closed, and the access route through the building is swept. Where the property is occupied or shared, that daily discipline matters more than anything else the household sees.
Who must agree before a load-bearing wall comes out in a Southwark flat?
Usually three parties before the engineer's design is final. 81% of homes in Southwark are flats. The freeholder or managing agent grants the licence to alter, since structure is normally outside the flat's demise. The owner above has a say where the floor between you is a party structure under the Party Wall Act, which a party wall surveyor can confirm. Building control then approves the calculations. Secure the licence first, as it can add conditions the design has to meet.
Are walls in Southwark's inter-war houses load-bearing like those in Victorian terraces?
Often, but for a different reason. Only 7% of Southwark homes were built between 1919 and 1939, so these houses are a minority here. In many houses of that period the roof is propped from struts that stand on an internal wall, so a ground floor wall can carry roof load as well as the first floor. The engineer checks the loft for struts before deciding what the wall supports.
What if a wall in a Southwark house was removed without approval before purchase?
It can be put right. Southwark Council's online form lets applicants begin a building regulations application as regularisation, as well as a building notice or full plans. Regularisation is the route for work already done without approval. The inspector needs to see the steel, its bearings and its fire protection, so ceilings and boxing are opened where the beam sits. Do it before new finishes go in, or combine it with any new structural work so one set of inspections covers both.
