Open-plan kitchen, diner and living conversions in Kensington and Chelsea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Kensington and Chelsea, opening up the compartmented interiors of stucco-fronted townhouses and red-brick period homes near Holland Park and the museums of South Kensington. With 30+ years in SW3, SW7, W8 and W10, we turn narrow Georgian room layouts into light-filled kitchen-diners and broken-plan living space, every steel engineered and certified.

The borough's Georgian and Regency townhouses were designed as sequences of separate rooms, so opening them up means removing masonry spine walls that carry real structural load. A simple knock-through between two reception rooms, a full kitchen-diner across the lower ground floor, or a broken-plan scheme with a Crittall divider all start the same way: a structural engineer assesses the wall and sizes the steel beam that replaces it. Nothing is knocked through on assumption.
We prop the structure, take the wall down in staged sections, and seat the new RSJ onto engineered padstones so the loads pass safely into the retained masonry. In many of the borough's homes a broken-plan approach, with a steel-framed Crittall screen holding a sense of separation, suits the tall proportions and period detailing better than a single unbroken space. We work around original cornicing, fireplaces and joinery wherever the design allows.
Removing an internal wall to open up your layout is structural work governed by the Building Regulations, and the Royal Borough of Kensington and Chelsea's building control inspects the beam, the padstone bearings and the propping before certifying it. This is not a planning matter for internal work. Only alterations to a listed property's fabric or a conservation-area frontage bring listed-building consent or planning into play, and we identify that at the design stage.
In South Kensington and Chelsea, where townhouses adjoin their neighbours, the wall being opened often meets or forms the party wall, and any beam bearing into that shared wall triggers the Party Wall Act. You serve notice on the adjoining owner before work begins. From the engineer's calculations to the steel, the making good and the final certificate, one GS Renovation team delivers the whole conversion under a single point of accountability.
Homeowners across Kensington and Chelsea choose GS Renovation for open-plan conversions because we combine design sensitivity with structural rigour. You get an engineer-designed beam and building control handled by one accountable team, careful staged working that protects period detail, and a certified, dust-managed result, all backed by 30+ years of conversions across the Royal Borough.

FAQ
Labour is the biggest line on almost every Kensington and Chelsea project. Materials for open-plan conversion are relatively predictable, but the days on site at SW3 depend on access, condition and how many trades must follow each other. GS Renovation sequences them to avoid idle time, which is the practical way to control the cost. The Kensington and Chelsea quotation shows where the hours go. Ring 07472 424 226 and GS Renovation will describe the sequence planned for your SW3 home. 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.
Usually yes, depending on which rooms are affected. For most open-plan conversion projects at an SW3 address we seal the work area, protect the routes through, and agree hours so a Kensington and Chelsea household can carry on. Where services are off for a period, GS Renovation tells you which days in advance. Full refurbishments are the exception, and we say so honestly. GS Renovation seals the SW3 work area and agrees hours before open-plan conversion begins in Kensington and Chelsea.
Yes, for practical reasons rather than sentimental ones. A contractor that works across Kensington and Chelsea and Westminster knows the Royal Borough of Kensington and Chelsea building control process, the parking constraints at SW3 and the way local houses were built, all of which affect an open-plan conversion job. GS Renovation has covered this area for years. Ask any firm for addresses of finished Kensington and Chelsea work. Email info@gsrenovationltd.co.uk for a free survey. Ask what happened when something went wrong on a previous job.
It can, and it is worth planning for. One large space in an SW3 property behaves differently to two small ones, so radiator sizing or underfloor heating is reconsidered as part of the Kensington and Chelsea conversion rather than left as it was.
Yes, and the age of the building is rarely the deciding factor. What matters for open-plan conversion is what the SW3 structure is carrying and what Royal Borough of Kensington and Chelsea requires, both established before design. GS Renovation appoints the engineer where the work needs one. The Kensington and Chelsea survey is free and carries no obligation in Kensington and Chelsea. Ask on 07472 424 226 exactly what open-plan conversion depends on at an SW3 address in Kensington and Chelsea before you decide anything at all.
For internal work, yes. Knocking two rooms into one is structural work under the Building Regulations, so the Royal Borough's building control signs it off rather than planning. Planning or listed-building consent only applies if your home is listed or the change affects a conservation-area exterior. We arrange the engineer's beam design, the building control notice for you.
Almost always, and it is a fair question to ask any contractor. Open-plan conversion across Kensington and Chelsea is core work for GS Renovation rather than an occasional job, so there is usually an SW3 project or a Kensington and Chelsea one under way. Ask to speak to those clients. Call 07472 424 226 and we will arrange it. Seeing finished work in Westminster is worth the trip. Nothing about an SW3 address is withheld if you ask.
