Open-plan kitchen, diner and living conversions in Surbiton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Surbiton, turning the compartmented ground floors of KT6's bay-fronted Victorian and Edwardian terraces into flowing kitchen-diners and broken-plan living. With more than 30 years in Kingston upon Thames, we combine the structural engineering, the steelwork and the finish so a knock-through feels seamless from bay window to rear return.

The classic Surbiton layout puts a front reception, a middle room and a kitchen in the rear closet wing behind a run of solid walls, and the spine wall dividing them is almost always load-bearing. To open the space we replace that wall with an engineer-sized steel beam bearing onto padstones, so the floors and rooms above are properly carried once the brick is gone.
Homeowners here often want more than a single vast room, so we plan broken-plan schemes with a Crittall-style glazed divider or a part-height wall keeping the front bay as a cosy sitting area while the middle and side-return kitchen become one bright diner. We prop, cut the opening in stages, set the steel and only then take the props down.
Because the beam carrying your new open-plan space bears into the party wall shared with the neighbour, the work is notifiable under the Party Wall Act. You serve notice on the adjoining owner early, so consent is in place before the steel goes in and the job runs to schedule without a stand-off over the shared wall.
Removing structural walls is controlled under the Building Regulations, so Kingston Council's building control inspects the propping, beam and bearings and issues the completion certificate. No planning permission is needed for internal open-plan work; planning only applies to exterior alterations in a conservation area or on a listed building. We book the inspections and keep the engineer's calculations on site throughout.
Surbiton homeowners choose GS Renovation because we deliver the whole open-plan conversion under one roof: structural engineer, sized steelwork to your neighbour and Kingston building control sign-off, through to a plastered, level finish. With 30+ years in KT6's terraces, we work tidily in your home and hand over a certified, seamless space you can enjoy for years.

FAQ
Free, always. Pricing open-plan conversion without seeing a Surbiton house is guesswork, so the visit to KT6 is part of quoting rather than a service to bill for. GS Renovation allows enough time on site to look properly, including at the Victorian and Edwardian terraced details that move the figure. Nothing is owed if you go elsewhere in Kingston upon Thames. Ring 07472 424 226 or email info@gsrenovationltd.co.uk and we will find a Surbiton appointment time that suits 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 KT6 property, open-plan conversion moves into plastering, decorating and sign-off, and that phase fills out the Surbiton programme. GS Renovation sets realistic dates rather than optimistic ones. Ring 07472 424 226 and we will give a range for a comparable Victorian and Edwardian terraced home in Kingston upon Thames. The Kingston Council inspection dates are marked on the Surbiton programme from the outset.
The structural work is ours, always. Electricians, plumbers and plasterers are engaged and coordinated by GS Renovation for an open-plan conversion project at a KT6 address, but they work to our programme and our named manager. The engineer, where open-plan conversion needs a design, is appointed by us too. Nothing about your Surbiton job is sold on. Ask for Kingston upon Thames references and check that yourself. Ask who would attend your KT6 home in Surbiton.
Internal work in a Surbiton house does not normally engage planning, but removing a load-bearing wall needs building regulations approval, engineer's calculations and Kingston Council sign-off. If the wall is shared with a neighbour the Party Wall Act may apply too. GS Renovation manages the whole process.
We do, week in and week out. Edwardian bay-fronted houses with generous ceiling heights and long rear gardens make up much of Surbiton, so open-plan conversion on them is core work for GS Renovation rather than an occasional job. The KT6 survey establishes what is actually there before anything structural is touched. Kingston Council building control is coordinated by us in the usual way. Ask on 07472 424 226 what a KT6 property of that age typically needs before open-plan conversion can even begin in Surbiton.
Usually yes, but the dividing wall in these terraces is load-bearing, so it cannot simply be removed. A structural engineer sizes a steel beam to carry the load onto padstones, we prop and work in stages, serve the party wall notice on your neighbour and get Kingston building control to sign it off. A broken-plan glazed divider is a popular alternative.
That postcode is well within the patch. GS Renovation carries out open-plan conversion throughout Surbiton and the KT6 area and into New Malden, with no surcharge for one part of Kingston upon Thames over another. Free survey, no obligation, and a written quotation afterwards. Email info@gsrenovationltd.co.uk with the address and we will arrange a visit. Building control goes through Kingston Council exactly as it does elsewhere. Small jobs and full projects are quoted on exactly the same basis in Surbiton.
