GS Renovation creates open-plan spaces across Battersea, turning the cellular rooms of SW11's Victorian and Edwardian terraces into bright kitchen-diners and connected living spaces. We handle the knock-through, the steel and broken-plan touches like Crittall dividers as one coordinated project.
In Battersea, 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 Battersea: 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 Battersea 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 Wandsworth 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 Battersea terraces
The classic Battersea terraced house layout separates a front reception, a rear reception and a kitchen in the closet wing, so opening it up usually means removing the wall between the two receptions or knocking through into the side return. Because these dividing walls typically carry load, a structural engineer sizes a steel beam for each opening so the floor and rooms above are safely supported once the wall is gone.
Many owners near Clapham Common and Wandsworth Common now prefer broken-plan to a single vast room, keeping some separation for warmth and quiet. Crittall-style glazed screens are a popular way to divide a kitchen-diner from the living area without losing light, and we set out the openings, with the steels as the engineer specifies them, so those dividers sit cleanly within the period proportions of the house.
Housing in Battersea
Battersea counts roughly 33,740 homes for Council Tax; 19% are older than 1919, 4% interwar and 76% post-war, with 91% flats and 9% houses. Most homes here are flats, and opening up a flat in Battersea changes its fire escape route, which building control checks.
Fire safety and sign-off for open plan in a Battersea flat
91% of homes in Battersea are flats, so an open plan scheme here is usually in a flat, and in a flat the wall that comes out is often the one that protected the route from the bedrooms to the front door. Take it away and the kitchen becomes part of the escape route. Its replacement has to be designed before demolition: fire doors to the bedrooms, linked detection, and sometimes a sprinkler or mist system, all agreed with building control as part of the application rather than added at the end.
Which body approves it depends on the block. Usually it is Wandsworth Building Control, which issues a completion certificate after it has been notified the work is complete and has carried out a satisfactory final inspection. In a tall block registered as a higher-risk building, which includes some of the newer riverside towers, the Building Safety Regulator takes that role instead, and approval has to be in place before work starts. We confirm which applies with the managing agent at survey, because it can add weeks before the first wall is touched.
Coordinated and signed off in SW11
A knock-through in these terraces is structural work, so it falls under the Building Regulations and is signed off by Wandsworth Council's building control, not planning permission. Planning is a matter for external changes, so most internal open-plan conversions proceed on building control approval alone once the engineer's design is in place. The exception is a listed home, which needs listed building consent for internal work too, including removing a wall.
Where the removed wall meets the party wall shared with next door, the Party Wall Act applies and you serve notice as building owner before work begins, using the drawings we supply. We prop safely, take the wall down in stages, set the beam onto padstones and then run the trades together, so your Battersea kitchen-diner is delivered as one tidy, certified job rather than a string of disconnected contractors.

FAQ
Frequently Asked Questions about Open-Plan Conversions Battersea
What happens to the open-plan conversion price if the scope changes in Battersea?
The open-plan conversion price in Battersea moves visibly when the scope changes, because the quotation is itemised within £3,000 to £8,000 or more (indicative). A change at SW11 is priced against the same lines rather than renegotiated, and any change touching the approvals, such as the engineer's calculations and building regulations approval of the steel, is flagged. GS Renovation issues a written variation and waits for approval.
Does a Battersea terrace open up well at the back?
It does, and the rear addition is usually the key to it. In a Battersea terrace the ground floor typically has two rooms plus a narrower rear wing, and combining all three produces a single space across the back with the garden beyond. That means removing more than one wall, so the structure is designed as one scheme rather than as separate openings taken in turn.
How is light brought into the middle of an open plan Battersea house?
From above, because the middle of the plan has no external wall. In a deep Battersea ground floor the centre sits furthest from any window, so rooflights over the junction between the original house and the rear wing are what stop it going dark. Where a side return is infilled, a run of glazing over that strip does the same. Daylight is designed in rather than added later.
What happens to the utility and storage in an open plan Battersea house?
They need somewhere deliberate to go, or the room fills with what used to be hidden. Opening up a Battersea ground floor removes the small rooms that held a washing machine, coats and everyday clutter. A utility cupboard, an understairs enclosure or a run of joinery is designed in from the start. Appliance noise in a room used for living is the usual complaint when it is not.
Does open plan living suit every Battersea household?
No, and it is worth saying before the walls come out. An open ground floor in a Battersea house means cooking, television and homework share one volume, with no door to close on any of it. If your household uses rooms separately at the same time, you may find it worse than what you had. A wide opening with doors within it keeps the light and the option to divide.
How is a Battersea open plan room lit at different times of day?
On separate circuits chosen before the ceiling is closed. One long room in your Battersea house serves cooking, eating and sitting, and a single pendant arrangement suits none of them. Task lighting over worktops, something softer at the sitting end and dimming on the main circuits are set out at first fix, because adding them later means chasing into plaster you have just paid for.
Will an open plan room in a Battersea flat be noisier for the neighbours below?
It can be, and the lease may already cover it. 91% of homes in Battersea are flats, so the room you open up usually has someone living underneath. Open plan layouts tend to swap carpet for hard flooring, which carries footfall straight through, especially on the timber joists of a converted house. Check the lease for a flooring or underlay clause before choosing finishes, and allow for an acoustic underlay or a resilient layer so the new floor performs no worse than the old one.
Does a Battersea conservation area stop an internal knock-through in a house?
No. Wandsworth's conservation area FAQ lists outside works, such as front and side extensions and two storey rear extensions, among those needing planning permission, and taking down an internal wall in an unlisted house is not one of them. The knock-through itself is a building regulations matter, unless the house is listed, when interior alterations that affect its character need listed building consent. What the designation does affect is any extension built at the same time, and on the Article 4 estates the list of works needing permission is longer.
How does the steel get into a Battersea flat in a converted Victorian house?
Through the common parts, which the lease controls. 19% of homes in Battersea were built before 1919, and a flat in one of those houses is reached by the original stair, which may be too tight to turn a beam long enough for a period reception room. The structural engineer we appoint can design it in bolted sections joined in the room. The managing agent is given the delivery date, and the hall and stair are protected and photographed before and after.
