GS Renovation creates open-plan spaces in Vauxhall homes, from flats in SE11's post-war and riverside blocks to the Georgian and Regency terraces, opening them into kitchen-diners and connected living areas. We handle knock-throughs, broken-plan layouts and Crittall dividers, with an engineer's beam carrying the loads and Lambeth building control signing it off.
In Vauxhall, 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 Vauxhall: 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 Vauxhall 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 Lambeth 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 living in Vauxhall's Georgian terraces
In the Georgian and Regency houses that make up Vauxhall's older minority, the classic conversion joins two front-to-back reception rooms, or opens the kitchen into the dining room, giving these tall period houses the light and flow they were never built for. The dividing wall is usually load-bearing, so we start with a structural engineer sizing a steel beam to carry the floors above, bearing onto padstones set into the flank walls at each end.
Not everyone wants a single vast room. Broken-plan layouts, with a Crittall-style glazed screen or a part-height wall, suit SE11's period proportions and keep some separation between cooking and sitting. Where the divider is glazed rather than structural we can be lighter-handed, but any wall taking load is still opened with propping and staged demolition under the engineer's design.
Housing in Vauxhall
The stock in Vauxhall runs to roughly 14,160 dwellings, 92% of them flats and 8% houses, built 22% before 1919, 14% between 1919 and 1939 and 64% after 1945. Since most homes here are flats, opening up a flat in Vauxhall changes its fire escape route, which building control checks.
A Vauxhall through lounge as Lambeth's building control schedule sees it
Lambeth's building control schedule names a through lounge as its own item, with its own total charge. That tells a Vauxhall owner two useful things. Joining the front and back rooms of a terraced house is building regulations work in Lambeth's eyes, not a decorating job, and the schedule lists items separately, so a scheme that also removes a chimney breast may involve more than one line. Terraced houses are only 8% of Vauxhall's homes, and in them the dividing wall is usually solid brick carrying the floor above.
Lambeth says its domestic charges apply to new applications deposited on or after 1st April 2024 and apply until further notice. The charge is set by the date the application is deposited, not the date the wall comes down, so check the current schedule on the day it goes in rather than relying on a figure quoted months earlier. Once the rooms are joined, ask the engineer to show the beam, its bearings and any fire protection on one drawing. That drawing is what the inspector checks against and what a buyer's solicitor later asks to see beside the completion certificate.
Getting it signed off across SE11
A knock-through is notifiable under the Building Regulations, so Lambeth Council's building control inspects the beam and its bearings and issues the completion certificate. This is building control rather than planning: opening up internally needs no planning permission, though a listed Vauxhall house, or exterior changes in a conservation area, can need consent, which we check before starting.
Where the new beam bears into the party wall shared with the neighbouring house, the Party Wall Act applies and you serve notice before work begins, using the drawings we supply. Because these conversions happen in lived-in homes, we prop carefully, dust-sheet and seal the working area, and manage the mess. You get an open, connected space that is engineered, certified and finished, not just knocked through.

FAQ
Frequently Asked Questions about Open-Plan Conversions Vauxhall
How does your open-plan conversion price in Vauxhall compare with a national firm's?
A GS Renovation price for open-plan conversion in Vauxhall compares well with a national firm's because there is no head office to fund, and both should sit within £3,000 to £8,000 or more (indicative). GS Renovation is the contractor doing the work at SE11, not a broker adding a margin. Compare the scope, including Lambeth Council building control sign-off of the beam and the Part B escape route, not just the total.
Are modern Vauxhall flats already open plan?
Most are, and the question is usually how to divide rather than how to open. Apartments built around Vauxhall in recent years generally combine living, dining and kitchen in one space by default, so owners more often want a study, a second bedroom or somewhere to close the kitchen off. That is a different problem from removing a wall and it has its own constraints.
Can a partition be added in a Vauxhall apartment?
Often yes, and it has to respect light, ventilation and escape. Subdividing an open space in your Vauxhall flat can leave the new inner room without a window, which affects whether it counts as habitable, and it changes the route to the entrance door. Sprinkler and detection coverage may also be affected. The freeholder's consent is required even where nothing structural is touched.
Why does a Vauxhall apartment sound echoey?
Hard finishes and one large volume with nothing to absorb sound. Flats around Vauxhall are frequently finished with resilient flooring, plasterboard walls and large areas of glass, which reflect sound rather than absorb it. Rugs, curtains, upholstered furniture and acoustic treatment where it can be accommodated all reduce it measurably. Adding a partition changes the acoustics as much as it changes the plan.
What will the management company allow in a Vauxhall building?
Less than owners generally expect, and it is set out in the lease. Buildings around Vauxhall commonly regulate floor finishes, alterations to services, working hours, lift use and waste removal, and some prohibit structural change outright. The alterations policy is obtained before any design work begins. A scheme designed against what the building permits cannot be built however good it is.
What flooring is permitted in a Vauxhall apartment?
Whatever the lease allows, and hard flooring is frequently restricted. Buildings around Vauxhall commonly require carpet or a specified acoustic underlay in habitable rooms, because impact sound travels readily through a concrete frame to the home below. Checking that before choosing a finish avoids a floor that has to come up again. Where hard flooring is permitted, the underlay specification is part of the consent.
Why does the engineer need to see the flat above before a Vauxhall knock-through?
Because the wall you want to lose may be carrying their partitions as well as their floor. In a Vauxhall terrace divided into flats, walls upstairs were not always built directly over walls downstairs, so loads can arrive at your wall in unexpected places. The structural engineer we appoint looks at the layout above before sizing the beam, and that visit needs the neighbour's agreement, so ask for it when you first raise the plan.
Which Lambeth application does a knock-through in a Vauxhall flat need?
One of Lambeth's two routes to building regulations approval: a building notice or a full plans application. In a block, ask Lambeth whether a building notice is accepted, as the fire safety rules for shared parts can require full plans. A riverside tower may be a higher-risk building under the Building Safety Act, where approval comes from the Building Safety Regulator, not Lambeth, so ask the managing agent first. The freeholder's licence usually takes longest anyway.
Will opening up a Vauxhall flat let more noise reach the flat next door?
Not through the wall you remove, which sits inside your flat, but the junctions matter. Where an internal wall met a wall or floor you share with a neighbour, taking it out leaves a gap in the finishes that lets sound travel along the structure. With 92% of Vauxhall's homes being flats, there is a neighbour on the far side in almost every case, so those junctions are made good in dense material before decorating.
