Open-plan kitchen, diner and living conversions in Teddington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces in Teddington's period homes, turning the compartmented rooms of a bay-fronted Victorian or Edwardian terrace into a bright kitchen-diner or a broken-plan living space. With 30+ years across TW11 and Richmond upon Thames, we combine engineer-designed steelwork with tidy finishing to open these houses up without compromising the structure.

The classic Teddington layout, a front reception, a middle room and a rear closet wing off the side return, was never meant to flow. Knocking the two reception rooms into one, or opening the kitchen through to the dining room, usually means taking out a load-bearing wall, so a structural engineer sizes a steel beam to carry the floors above onto padstones at each end before any wall comes down.
Not every homeowner wants a single vast room. Broken-plan is popular in these terraces: a wide structural opening keeps the sightline and light while a Crittall-style glazed divider defines the kitchen from the sitting area. Whether it is a full knock-through or a part-height break, the load path is worked out first and the beam installed on props, in stages, so the structure is supported throughout.
An open-plan conversion inside a Teddington house is a Building Regulations job, not a planning one, so no planning permission is needed for the structural opening itself. Richmond Council's building control inspects the beam, its bearings, the propping and the completed work. Planning or listed-building consent only enters the picture if you are also altering the exterior in a conservation area or your home is listed, which we will identify at the survey.
Because the new beam frequently bears into the flank wall shared with the neighbouring terrace, the Party Wall Act often applies and you serve notice on the adjoining owner before starting. From the engineer's calculations through to the steelwork, plastering and reinstated flooring, one team runs the whole conversion so your new kitchen-diner is delivered fully certified and finished.
For an open-plan conversion in Teddington, GS Renovation gives you one accountable team from survey to certificate: engineer-sized steel served on your terrace neighbours, and Richmond Council building control managed throughout. We prop and demolish in safe stages, protect an occupied home from dust, finish neatly around Crittall dividers and steel, and back it with 30+ years in TW11.

FAQ
Set the figure after the survey rather than before it. Guessing an open-plan conversion budget for a Teddington home usually means guessing wrong in one direction or the other, and the TW11 visit costs nothing. GS Renovation then gives you an itemised written total including the Richmond Council element. Call 07472 424 226 or email info@gsrenovationltd.co.uk to arrange it. The TW11 visit carries no obligation at all, whether the Teddington work goes ahead or not. 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.
Modern stock is usually faster to finish. Where open-plan conversion is concerned the difference shows after the structural stage, because a bay-fronted Victorian terraced Teddington property needs far more reinstatement around the TW11 works. GS Renovation allows for that difference in the programme it issues. Both types are surveyed the same way in Richmond upon Thames before any dates are committed. Ask GS Renovation on 07472 424 226 what a bay-fronted Victorian terraced property at TW11 is likely to require in practice.
Yes, that is included. GS Renovation submits the Richmond Council building control application for open-plan conversion at your TW11 property, books and attends the inspections, and sees the completion certificate through. Where the design needs a structural engineer we appoint and coordinate them. A Teddington homeowner is left with the party wall notices to serve, and we prepare those. Ring 07472 424 226 and we will explain the Richmond upon Thames steps. The party wall duty stays with you as Teddington building owner.
Building regulations, principally structure. The beam is sized by an engineer and inspected by Richmond Council before it is concealed. Fire separation also matters where the Teddington conversion opens a stairwell, because escape routes must stay protected under Part B.
Damp, decayed timber and load paths that are not where anyone expected. Two and three-bedroom Victorian terraces, a good many now split into flats hide all three, which is why open-plan conversion at a TW11 address starts with careful opening up rather than demolition. GS Renovation tells a Teddington homeowner immediately and prices the fix in writing. Nothing proceeds on a Richmond upon Thames site until you have agreed it. Email info@gsrenovationltd.co.uk and we will explain how open-plan conversion variations are agreed at a TW11 property.
Usually yes. Knocking two reception rooms together is internal structural work governed by the Building Regulations, not planning, so planning permission is not needed for the opening itself. Richmond Council building control signs off the beam and bearings. You would only need planning or listed consent for exterior changes or a listed home. Where the beam bears into the shared party wall, you serve the neighbour notice first.
The whole borough, and beyond it. Open-plan conversion takes GS Renovation across Teddington, Twickenham and much of South West London in a normal month, and there is no surcharge for a TW11 address in one part of Richmond upon Thames over another. Building control goes through Richmond Council either way. Ring 07472 424 226 to confirm your street. The survey that follows is free and carries no obligation.
