Open-plan kitchen, diner and living conversions in Harlesden. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan living in Harlesden's Victorian and Edwardian terraces, turning cramped front-middle-rear layouts into flowing kitchen-diners. Across NW10, from streets near the town centre to homes closer to Willesden and Kilburn, our 30-plus years of structural experience means we open these terraces up properly, with the right steel behind every knock-through.

The classic Harlesden terrace was built as a string of small, separate rooms, so an open-plan conversion usually means knocking through the two reception rooms, or joining the rear room to a side-return kitchen to create one bright kitchen-diner. Because the walls between them typically carry load, a structural engineer designs the beam, its bearings and the padstones so the floor above stays fully supported once the wall comes out.
Not everyone wants a single vast space, and broken-plan suits these terraces well: a Crittall-style glazed divider or a part-height wall can define a snug or study while keeping light flowing through the depth of the house. We build the structural opening first, then set out these dividers so they land cleanly against the new steel and the original bay-fronted proportions still read.
Every knock-through in these terraces is an RSJ job done properly: temporary propping to take the load, a beam sized by the engineer bearing onto padstones at each end, and staged demolition so the structure is never overloaded. Because the opening usually bears into the shared party wall, the work is notifiable under the Party Wall Act and you serve notice on your Harlesden neighbours first.
Opening up the ground floor is a Building Regulations matter rather than a planning one, so Brent Council building control inspects the beam and signs it off; you do not need planning permission for the internal structure. We coordinate the engineer, the propping, the steel and the sign-off, then finish the plastering and levels so your new kitchen-diner feels like one considered, seamless space.
For open-plan conversions in Harlesden, GS Renovation gives you one accountable team from concept to certificate. We commission the structural engineer, size and install the steel on padstones, serve Party Wall Act notices on neighbours and secure Brent Council building control sign-off, all while working tidily in your terrace, backed by more than 30 years of structural experience across NW10.

FAQ
Everything needed to finish the work and get it signed off. The open-plan conversion quotation for a Harlesden home covers labour, materials, the structural engineer where the design requires one, the Brent Council building control element, and the making good afterwards. Anything genuinely uncertain at the NW10 property is flagged before we start rather than added later. GS Renovation issues it after a free NW10 survey, with no obligation in Harlesden or the wider Brent. 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.
We will tell you exactly, once we have seen the house. Guessing an open-plan conversion duration for a Harlesden property without a survey helps nobody, and the NW10 visit is free. GS Renovation then issues a staged programme including the Brent Council inspection dates and the drying time that cannot be rushed. That is the version to plan a Brent household around. Ring 07472 424 226 and we will describe how a similar NW10 job ran in Brent.
Mostly because the process is clear from the first visit. You get an itemised quotation for open-plan conversion, a written programme for the NW10 property, and one person to call throughout the Harlesden job. We are fully insured, company number 14611254, and GS Renovation handles the Brent Council approvals rather than leaving them with you. Read the 31 MyBuilder reviews before deciding on a Brent builder. Ask for NW10 addresses of finished Brent work.
Often a better one. Part-height walls, Crittall-style glazed dividers and level changes keep zones defined in a Harlesden home while still opening the space up. The structural work is the same, but the result suits how many households actually live.
We can, and we would tell you early if we could not. Open-plan conversion in solid-wall Victorian terraces with original chimney breasts and suspended timber floors occasionally runs into a structure that will not do what the owner hoped, and finding that out at the NW10 survey is far better than on site. GS Renovation is honest about it before a Harlesden client commits. The visit is free either way. Brent Council building control is coordinated by GS Renovation on every open-plan conversion project in Brent.
In most cases yes, but the dividing wall in these terraces is usually load-bearing, so it must be replaced with a properly sized steel beam on padstones, not simply removed. A structural engineer designs it, the work is notifiable under the Party Wall Act and Building Regulations, and Brent building control signs it off. We manage the whole process.
