Open-plan kitchen, diner and living conversions in Borough. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan living across Borough and SE1, opening up the bay-fronted Victorian and Edwardian terraces that fill this part of Southwark. From knock-throughs to kitchen-diners and broken-plan layouts with Crittall dividers, our 30+ years of structural work means the walls come out safely, on engineered steel, and the space finally flows.

The classic Borough terrace divides into a bay-fronted front room, a middle room and a kitchen in the rear closet wing, all separated by walls that made sense in the 1890s but cramp the way people live today. A through-lounge knock-through, or opening the middle room into the side return to form a bright kitchen-diner, transforms these homes, and it is work we do regularly across SE1 towards Peckham, Dulwich and Bermondsey.
Not every homeowner wants one vast room, so broken-plan is popular here too. A Crittall-style glazed divider keeps a distinct kitchen while letting light travel through the plan, and it needs the same structural care as a full removal. Wherever a dividing wall carries load, an engineer sizes a beam on padstones, we prop temporarily and demolish in stages, so the open feel never comes at the cost of the structure above.
Because these dividing walls are usually part of, or tie into, the party wall shared with the neighbouring terrace, forming a wide opening is notifiable under the Party Wall Act. You serve notice on the adjoining owner before work begins, whether we are knocking two rooms together or cutting the opening for a Crittall screen, so the shared masonry is properly accounted for.
Opening up a floor is internal structural work, so it falls under the Building Regulations and Southwark Council's building control, not planning permission. Planning only applies to exterior changes in a conservation area or on a listed building. We manage the engineer's design, safe staged demolition and building control sign-off, then finish the flooring and plaster so your new open-plan space is ready to enjoy.
For open-plan conversions in Borough, GS Renovation gives you one accountable team across SE1. We engineer the beam, serve the party wall notice, manage Southwark building control and finish the space cleanly, whether it is a full knock-through or a broken-plan layout with a Crittall divider. Tidy working in your home and 30+ years across South London back every job.

FAQ
Check what has been left out before deciding. Cheap open-plan conversion quotations in Borough tend to be rather light on approvals and reinstatement, and work started without Southwark Council sign-off becomes expensive when the SE1 property is sold. GS Renovation includes both as standard. We would rather lose the job than win it by omission. Ring 07472 424 226 and GS Renovation will explain what a complete Southwark quotation should contain, and what it should not. As a rough guide, open-plan conversion in London typically costs from roughly £3,000 to £8,000 or more, including the steel beam and finishing (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
It depends on scope, and we will not pretend otherwise on the phone. Once the SE1 survey is done GS Renovation can give a Borough homeowner real dates for open-plan conversion, including the Southwark Council inspection points. Material lead times are ordered against that programme early. Ring 07472 424 226 and we will describe what a bay-fronted Victorian terraced property usually needs. Nothing about the Borough dates is guessed once the free survey at SE1 is done.
Communication is the difference most clients mention. You get a weekly update on the open-plan conversion project at SE1, and if something changes on the Borough job you hear it from GS Renovation first rather than at handover. The quotation is itemised and the programme is written. Neither is normal in this trade, and both are why Southwark work keeps coming from referrals. Ring 07472 424 226 to discuss it. Ask on 07472 424 226 who would manage your Southwark job.
Often a better one. Part-height walls, Crittall-style glazed dividers and level changes keep zones defined in a Borough home while still opening the space up. The structural work is the same, but the result suits how many households actually live.
Sometimes, depending on where the property sits. Open-plan conversion in bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns within a conservation area is usually possible but more constrained in form, and Southwark Council will scrutinise anything visible from the street at SE1. GS Renovation handles the application and the negotiation. Internal work in a Borough house is generally more straightforward. Ring 07472 424 226 and we will explain what Southwark Council is likely to ask about open-plan conversion at an SE1 address of that age.
In most cases yes. The dividing walls in SE1 terraces are often load-bearing, so a structural engineer sizes a steel beam on padstones and we prop before staged demolition. Because the wall ties into the shared party wall, you serve notice on your neighbour, and Southwark building control signs off the finished opening under the Building Regulations.
There is none, and it is worth asking even if the job feels too small. Open-plan conversion enquiries across Borough range from a single opening to a whole-house programme, and GS Renovation quotes both on the same basis. The SE1 visit costs nothing and carries no obligation. Email info@gsrenovationltd.co.uk with a description and some photographs. Building control still goes through Southwark Council where the work requires it. Small open-plan conversion work at SE1 is quoted the same way.
