Open-plan kitchen, diner and living conversions in Kennington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan and broken-plan living in Kennington's period homes, opening up the compartmented ground floors of SE11's Georgian and Regency townhouses. With 30+ years of structural experience in Lambeth, we knock through, form kitchen-diners and fit Crittall dividers, all properly supported and building-control certified.

Georgian and Regency townhouses in Kennington were designed as separate front and rear rooms divided by a solid spine wall, which is precisely why so many SE11 owners want them opened out into a single light-filled space. Because that dividing wall is load-bearing, a knock-through is never just a demolition job. A structural engineer sizes the steel beam that will span the new opening and carry the floors above once the wall has gone.
We install the beam onto padstones, prop the structure while we work, and take the wall down in staged sections so the load transfers safely onto the new steel. Many Kennington clients now prefer broken-plan layouts, using a wide structural opening with Crittall-style glazed dividers to keep a kitchen-diner feeling connected yet distinct, which also respects the proportions of a period room rather than gutting it completely.
An open-plan conversion in Kennington is governed by Building Regulations, not planning permission, so Lambeth Council's building control inspects the beam and its bearings against the engineer's calculations and issues the certificate you will want on record. Where the new beam bears into the party wall shared with your neighbour, the Party Wall Act applies and you serve the required notice before starting, so consents are in place from day one.
Many Kennington houses are listed or within a conservation area, which affects the exterior rather than an internal knock-through; we keep the structural work inside and flag early if a change would ever reach a controlled facade. The result is a bright, connected ground floor, ready for a kitchen-diner opening onto the garden, delivered with the sightlines you would expect near Vauxhall and the South Bank and fully certified.
Kennington owners choose GS Renovation for open-plan work because one team carries it from engineer's design to finished, replastered space. We handle the steel, Lambeth building control and Crittall dividers, work cleanly in your occupied period home, and bring 30+ years of SE11 structural experience to every knock-through.

FAQ
Budget for the work itself plus a sensible contingency for what a survey cannot see. On a Georgian and early Victorian property near SE11 the usual unknowns with open-plan conversion sit behind plaster and under floors, so GS Renovation prices what is visible and flags the rest openly. The Lambeth Council building control fee belongs in your Kennington budget too. GS Renovation would rather over-explain a Lambeth figure than surprise a Kennington homeowner halfway through the work. 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.
Longer than the fastest quote you will be given, and shorter than an open-ended one. GS Renovation would rather set open-plan conversion dates a Kennington homeowner can plan around than win the SE11 job on a programme nobody can meet. The stages, the trades and the Lambeth Council points are all written down. You are updated against them weekly throughout the Lambeth project. Ring 07472 424 226 and we will describe how a comparable SE11 project ran.
You get the Lambeth Council completion certificate, the guarantee and a number that still answers. Installations carry a five year guarantee, and if something needs attention at your SE11 property after open-plan conversion is signed off you reach the same people who did the Kennington work. GS Renovation does not route aftercare through a call centre. Nothing about that is a brochure line. Ring 07472 424 226 whenever a Lambeth issue arises. The guarantee covers Lambeth installations for five years.
It can, and building control will look at it closely. Opening a hallway into a living space in a Kennington property removes the protected route to the front door, so interlinked alarms and sometimes a protected alternative are required. We resolve that with Lambeth Council at design stage.
It changes the making good more than the structural element. Listed period houses with sash windows, lime plaster and original joinery rarely have square openings or regular floors, so open-plan conversion at an SE11 property takes longer in plaster and joinery than in a modern house. GS Renovation shows that as a separate line on the Kennington quotation. The survey that establishes it is free. GS Renovation will explain on 07472 424 226 how open-plan conversion is actually priced at an SE11 address in Kennington itself.
For internal structural work, no. Knocking through in your Kennington home is governed by Building Regulations, and Lambeth building control signs off the steel beam, not the planning department. Planning and listed-building consent only come into play if you alter the exterior, which many SE11 conservation-area homes have. A pure internal knock-through stays a building control matter, and we manage that certification.
Further than most people expect, though we are honest about the limit. GS Renovation covers Kennington and the SE11 area and neighbouring Lambeth for open-plan conversion without a surcharge, and will still consider properties beyond Brixton. What matters is whether we can service the SE11 site properly through to aftercare. Email info@gsrenovationltd.co.uk and we will tell you either way. Nothing is owed for asking. Aftercare and snagging are treated as part of the same SE11 commitment.
