Open-plan kitchen, diner and living conversions in London. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces in homes across London, from knock-throughs in Camden terraces to kitchen-diners opening onto side returns in Wandsworth and Islington. With over 30 years of structural work across Greater London, we take out the walls between rooms, carry the loads on hidden steel and open period homes up for modern living.

The bay-fronted Victorian and Edwardian terraces that fill London were built as a series of small, separate rooms, so opening them up almost always means removing structure. A front-to-back knock-through joining two reception rooms, a kitchen-diner formed by taking out the wall to the rear closet wing, or a broader opening onto a side return each relies on a steel beam to replace the wall that was carrying the floors and roof above.
Not every wall in these homes is load-bearing, though. Some later partitions come out with no structural implication, while the original spine wall is very much doing a job. We tell you which is which after the engineer's survey, so you know exactly where steel is needed. Where you want a lighter division rather than one huge space, we can frame in a Crittall-style screen for broken-plan living that keeps light flowing without losing the beam's structural role.
Every open-plan conversion we carry out across London is engineered before it is built. The structural engineer sizes the beam, we prop the floors and roof, take the wall down in stages and seat the steel on padstones at each end so the load transfers cleanly. Because the loads in these terraces run down into the shared party wall, the notices under the Party Wall Act are served on the neighbour before we start.
Opening up the ground floor is controlled under the Building Regulations rather than planning permission, so building control inspects the beam and its bearings and issues the completion certificate. Internal structural work needs no planning consent across Greater London; only altering the exterior in a conservation area or to a listed building does. We manage the engineer, the party wall procedure, the steel and the sign-off, and finish the space ready to decorate.
London homeowners choose GS Renovation for open-plan work because we deliver it as one structural package: engineer-sized steel where loads sit in the shared wall, building control sign-off and clean working in your home. More than 30 years knocking through terraces across Greater London means the beam is hidden, the floors stay level and the room feels genuinely open.

Punctual, worked hard, and did exactly what he was asked and what he said he would do. Overall, a very high quality job. Will use again.

FAQ
Only if it covers the same work, and usually it does not. A low open-plan conversion figure for a London home normally excludes the engineer, the local authorities across London application or the making good, all of which still have to be paid for at the London property. GS Renovation itemises so the comparison is honest. Ask the cheaper London quotation for the same breakdown. Ring 07472 424 226 and GS Renovation will go through both London quotations with you. 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.
More weeks than the structural work alone suggests. Once the beam or the opening is in at your London property, open-plan conversion moves into plastering, decorating and sign-off, and that phase fills out the London programme. GS Renovation sets realistic dates rather than optimistic ones. Ring 07472 424 226 and we will give a range for a comparable late Victorian and Edwardian home in London. The local authorities across London inspection dates are marked on the London programme from the outset.
Not a call centre, and not a different voice each week. GS Renovation assigns one manager to your open-plan conversion project, who surveys the London property, writes the programme and stays accountable until the local authorities across London certificate is issued. That is the single biggest reason London clients say the process felt calm. Ring 07472 424 226 and you will speak to them about your London job directly. That manager is your only point of contact in London.
It can, and it is worth planning for. One large space in a London property behaves differently to two small ones, so radiator sizing or underfloor heating is reconsidered as part of the London conversion rather than left as it was.
Only where the property genuinely warrants it. Open-plan conversion is priced from what the London survey finds rather than from the age on the deeds, so a well-maintained London house of that period is not loaded with a period premium. GS Renovation itemises so you can see the reasoning. Comparing that against another London quotation is straightforward. Ring 07472 424 226 and we will explain how an open-plan conversion quotation is built up at London.
In most cases, yes. It usually means removing a load-bearing wall and installing an engineer-sized steel beam on padstones to carry the floors and roof above. The work is controlled under the Building Regulations, so building control signs it off, and where the load meets the shared party wall you serve notice on the neighbour. We handle the whole process end to end.
We do not think of it as travelling, because London is inside our normal working area. Open-plan conversion projects run across London most weeks, so reaching a London address is routine and there is no surcharge for it. GS Renovation also returns for aftercare, which matters more than the initial journey. Ring 07472 424 226 and we will confirm the position. The survey costs a London homeowner nothing. Snagging visits to London are equally routine.
