Open-plan kitchen, diner and living conversions in Kensington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Kensington, opening up the reception floors of Georgian and Regency townhouses near Holland Park and the King's Road. With more than 30 years in W8 and the Royal Borough, we handle knock-throughs, kitchen-diners, broken-plan layouts and Crittall dividers, all engineered, propped and signed off under the Building Regulations.

Kensington's period townhouses were laid out as a series of separate rooms divided by solid masonry cross walls, so opening them up almost always means removing a load-bearing wall rather than a stud partition. A knock-through between the front and rear reception rooms, or a wide kitchen-diner at garden level, needs a structural engineer to size the steel beam that will carry the floors and storeys above once the dividing wall is taken out.
Not every client wants a single vast space in a home of this character, so broken-plan is popular in W8: a supported opening keeps the rooms connected while Crittall-style glazed dividers preserve some separation and let the light through. Whichever route suits your townhouse, the beam bears onto padstones, temporary props hold the structure during a staged demolition, and the original proportions are respected as the layout opens up.
Knocking two rooms into one is structural work under the Building Regulations, so the Royal Borough of Kensington and Chelsea's building control inspects the propping, the beam and the padstones and certifies the finished job. This does not require planning permission for the internal change; planning or listed-building consent only bites if you also alter a protected exterior or, in a listed home, its safeguarded interior fabric, and we keep those approvals distinct.
Where the dividing or party wall is shared with the neighbouring townhouse, the Party Wall Act applies and you serve notice before work begins. Many Kensington properties are listed or fall within conservation areas, so we confirm that status at the outset and factor any consent into the design. From engineer's calculations to the final plaster around a Crittall screen, we run the process so your open-plan floor is fully compliant.
Kensington homeowners choose GS Renovation for open-plan conversions because one accountable team takes the townhouse from closed rooms to a flowing, compliant space. We arrange the engineer's beam design, serve check any listed or conservation status, and secure the Royal Borough's building control sign-off, propping and working cleanly throughout, backed by more than 30 years in W8.

FAQ
Ask three builders in Kensington and Chelsea and you will get three different numbers for open-plan conversion, usually because they have scoped three different jobs. We price the W8 property after a survey and set out labour, materials, approvals and making good line by line. A Kensington homeowner can then see where any difference actually sits. GS Renovation puts all of it in writing. Ring 07472 424 226 and GS Renovation will arrange a free survey at your W8 property. 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.
Very little, provided the inspections are booked ahead. Royal Borough of Kensington and Chelsea needs to see the structural work on an open-plan conversion job at a W8 property before it is concealed, so GS Renovation schedules those visits into the Kensington programme rather than calling at the last minute. The completion certificate follows the final inspection. Waiting on paperwork in Kensington and Chelsea is a planning failure, not an inevitability. GS Renovation attends every Royal Borough of Kensington and Chelsea inspection at the W8 property on your behalf.
The same person throughout, and you will have their direct number. They own the open-plan conversion programme for your Kensington home, agree any variation in writing before it happens at W8, and provide the weekly update. GS Renovation does not rotate managers mid-project. Where a structural engineer is required they are appointed and coordinated by that manager too. Ask for Kensington and Chelsea references and check it. Ring 07472 424 226 and GS Renovation will name the W8 manager for Kensington.
It can, and it is worth planning for. One large space in a W8 property behaves differently to two small ones, so radiator sizing or underfloor heating is reconsidered as part of the Kensington conversion rather than left as it was.
It does, and the difference starts at the survey. GS Renovation cannot rely on assumptions about how a period, Georgian and listed Kensington house is built, so open-plan conversion begins with establishing the facts at W8. Everything after that follows from what is found. Over 30 years of hands-on experience is what makes that reading accurate. Ask on 07472 424 226 what the W8 survey has to establish in Kensington before any open-plan conversion work can actually begin.
In most cases yes, but the dividing wall in a Georgian or Regency townhouse is usually load-bearing, so a structural engineer must size a steel beam to replace it. The work is signed off by the Royal Borough's building control under the Building Regulations. If the wall is shared with the neighbour, the Party Wall Act also applies, and You serve those notices.
Yes, boundaries are not something we price against. Open-plan conversion runs across Kensington and Chelsea and into Central London, so an address on the edge of Kensington or over towards Chelsea is no harder to service. GS Renovation will say plainly if travel makes it impractical. Ring 07472 424 226 with the W8 postcode and we will confirm. The survey that follows is free and carries no obligation. Aftercare is no more difficult a few streets further out.
