Open-plan kitchen, diner and living conversions in Wimbledon. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan and broken-plan spaces in Wimbledon's Victorian and Edwardian terraces, turning cramped reception rooms and closet wings into flowing kitchen-diners. With more than 30 years across SW19, we know how these bay-fronted homes near Wimbledon Common are built, and how to open them up without losing their period character.

The classic Wimbledon knock-through joins the front bay reception to the middle room, or opens the kitchen in the rear closet wing into the dining space, so the whole ground floor works as one. Because the dividing wall almost always carries floor and roof loads above, an engineer sizes a steel beam for the span and specifies padstones before a single brick is removed.
Not every project wants a single vast room. Broken-plan schemes using Crittall-style glazed dividers keep light flowing while giving the cook and the dining table a little separation, which suits these period proportions well. Whether it is a full knock-through or a glazed screen, the structural opening is formed the same careful way: propped, cut in stages, beam seated on padstones, then finished.
Opening up a Wimbledon terrace is building control work under the Building Regulations, not a planning matter, so Merton Council's building control checks the engineer's calculations and inspects the beam and its bearings before issuing a completion certificate. If your home falls within a Wimbledon conservation area, only exterior alterations would need separate planning consent, the internal knock-through does not.
Where the wall being opened meets the shared party wall with the neighbouring terrace, the Party Wall Act applies and you serve notice next door beforehand. We manage the whole conversion under one roof: engineer, propping and safe demolition, the beam and any Crittall dividers, plus the plastering and making good that turns a structural opening into a finished, liveable open-plan space.
Wimbledon homeowners choose GS Renovation for open-plan conversions because one team carries the job from first idea to finished room: engineer's beam design where the terrace is shared, building control sign-off with Merton, and tidy working around your family in an occupied SW19 home. Thirty years in these terraces means the result is both open and structurally sound.

FAQ
No. Open-plan conversion is priced from scope, so a Wimbledon home is not quoted higher than the same house over in Mitcham. Where costs do rise is in period stock and awkward access, both of which are checked at the SW19 property. GS Renovation shows those as separate lines so you can see the reason. The SW19 survey costs nothing and there is no obligation afterwards, in Wimbledon or anywhere in Merton. 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.
Most of the disruption lands in the first phase and then eases considerably. The structural stage of open-plan conversion at an SW19 property is noisy and dusty for a defined period, after which your Wimbledon home comes back in stages. GS Renovation dust-seals the work area, protects floors and clears up daily. Working hours are agreed before we start anywhere in Merton. Ring 07472 424 226 and GS Renovation will explain what to expect at your SW19 address.
All 31 of them, on MyBuilder, where they cannot be edited by us. They cover open-plan conversion and the rest of what GS Renovation does across Wimbledon and Mitcham, and the 4.9 average is the honest picture rather than a selected one. References for an SW19 property are available on request. Ring 07472 424 226 and we will point you at recent Merton work. Nothing in those reviews is selected or edited by GS Renovation in Wimbledon.
Building regulations, principally structure. The beam is sized by an engineer and inspected by Merton Council before it is concealed. Fire separation also matters where the Wimbledon conversion opens a stairwell, because escape routes must stay protected under Part B.
There can be, and we check before any design work begins. Conservation area status, an Article 4 direction or a listing removes permitted development rights at an SW19 address, so open-plan conversion may need a full application to Merton Council. GS Renovation establishes the position for your Wimbledon home first. Building regulations apply regardless of the planning route. Ring 07472 424 226 and we will confirm the designation before any open-plan conversion design work at SW19.
In most cases, yes. The wall between the rooms usually carries load, so a structural engineer sizes a steel beam on padstones to replace it, and Merton's building control signs the work off. It is building regulations work, not planning, unless you are also altering the exterior in a conservation area. We handle the design and the build.
We work there constantly. Open-plan conversion in SW19 makes up a good share of what GS Renovation does across Wimbledon, which is why the survey can usually be arranged quickly. The Merton Council building control process is the same throughout Merton. Call 07472 424 226 and we will give you the next available slot. Nothing is owed for the visit or the written quotation. Aftercare visits reach that postcode as easily as the Wimbledon survey did.
