Open-plan kitchen, diner and living conversions in Isleworth. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan and broken-plan living across Isleworth, turning the tight rooms of TW7's Victorian and Edwardian terraces into flowing kitchen-diners. With more than 30 years of structural experience in this riverside part of Hounslow, we handle the knock-throughs, the steel and the finish that make these period homes feel twice the size.

The classic Isleworth terrace, with its front bay, middle room, rear closet wing and side return, lends itself perfectly to opening up. Homeowners here typically want the two reception rooms knocked through, or the kitchen combined with the wing into one bright kitchen-diner. Because the walls between these rooms usually carry load, every knock-through starts with a structural engineer sizing the right steel.
We install a beam onto padstones with temporary propping in place, then demolish in safe, staged sections so nothing is left unsupported. Not every homeowner wants a single vast space, so we also form broken-plan layouts and fit Crittall-style glazed dividers, keeping a sense of separate rooms while letting light travel from the front bay right through to the garden.
Where a knock-through runs to the party wall, or a beam needs to bear into masonry shared with your neighbour, the Party Wall Act applies and you serve the notice before work starts. That keeps the shared wall in these packed Isleworth terraces dealt with properly and your neighbour informed, which matters when you both live wall to wall.
An open-plan conversion is a Building Regulations job, not a planning one, so no planning permission is needed to knock rooms together internally. Hounslow Council's building control inspects the steel, its bearings and any ventilation or fire requirements and signs it off. We coordinate the engineer, the building control inspections and the plastering so you get one finished, certified space.
Isleworth homeowners choose GS Renovation for open-plan work because one accountable team carries the whole project: the engineer's beam design on your neighbour, safe staged demolition, Hounslow building control sign-off and a clean plastered finish. We work tidily in your occupied TW7 home and stand behind the result with more than 30 years locally.

FAQ
By surveying first and writing it down afterwards. An Isleworth property is measured, the structure is confirmed, and the open-plan conversion scope is agreed before GS Renovation puts a figure to it. The quotation then splits into structure, services and finishes, with the Hounslow Council fee visible rather than bundled. Homeowners around TW7 can hold us to it, because it is in writing. Ring 07472 424 226 or email info@gsrenovationltd.co.uk to book the TW7 visit. 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 something that could have been foreseen at survey. In bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns the classic hold-up on open-plan conversion is discovering the structure at a TW7 property is not what the drawings suggested, which is why GS Renovation investigates before committing to an Isleworth programme. Beyond that it is inspection slots and deliveries. Both are booked ahead across Hounslow. GS Renovation investigates the structure at the TW7 property before any Isleworth date is committed to paper.
Happily. Previous Isleworth clients are usually willing to talk about how an open-plan conversion project actually ran, including what went wrong and how GS Renovation dealt with it. We will point you at recent work near TW7 and in Chiswick. The 31 MyBuilder reviews behind our 4.9 rating are public and cover the same ground. Ring 07472 424 226 to arrange a Hounslow introduction. Nothing about a Hounslow reference is curated by us at TW7.
It can, and it is worth planning for. One large space in a TW7 property behaves differently to two small ones, so radiator sizing or underfloor heating is reconsidered as part of the Isleworth conversion rather than left as it was.
Rushing the investigation to save a few days. Everything difficult about open-plan conversion in a late Victorian and Edwardian Isleworth house is manageable if it is found at the TW7 survey and priced honestly, and expensive if it is found on site. GS Renovation takes the time first. That is why our fixed prices across Hounslow tend to stay fixed. Email info@gsrenovationltd.co.uk and we will explain what the TW7 survey checks before open-plan conversion is priced.
Absolutely. Many Isleworth homeowners prefer broken-plan to a single open box. We can form a wide structural opening for flow while fitting a Crittall-style glazed divider or a part-wall to zone the kitchen-diner from the reception. The engineer still sizes the steel over the opening and Hounslow building control signs it off, so you get light and connection without losing every sense of separate rooms.
We work on both, and the difference is consent rather than construction. An Isleworth flat needs the freeholder's agreement before open-plan conversion begins, and in a period block the structure at TW7 may be carrying load from several storeys. GS Renovation establishes that with an engineer first. The survey across Hounslow costs nothing. Ring 07472 424 226 and we will explain the Hounslow Council position. Freeholder consent is confirmed before any TW7 design work begins.
