Open-plan kitchen, diner and living conversions in Richmond upon Thames. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces in Richmond upon Thames, opening up the compartmented layouts of Georgian, Regency and Victorian homes across TW1, TW9 and SW13. With 30-plus years of structural experience in the borough, we handle knock-throughs, kitchen-diners, broken-plan schemes and Crittall dividers, engineering the steel so period homes flow without losing their character.

Richmond's period houses were built as a series of small, separate rooms, so opening them up nearly always means taking out load-bearing masonry. A double knock-through to make one reception room, or joining the kitchen to a rear diner in a Teddington terrace, needs a structural engineer to size the steel that will carry the floors and walls above once the dividing wall has gone.
We favour a broken-plan approach in these homes, keeping a sense of the original proportions rather than gutting everything to one box. A steel beam on padstones can be boxed in flush or left exposed, and Crittall-style glazed dividers let light travel through while still marking the old room lines, which suits the borough's conservation-area streets and their more restrained character.
The beam that makes an open-plan space possible has to be right. Our engineer sizes it for the actual loads, we set it on padstones at each end, prop the structure above and take the old wall down in stages before removing the props. Getting the steel and its bearings correct is what keeps floors level and doors square long after the work is finished.
Knocking through is notifiable under the Building Regulations, not planning, so Richmond Council's building control inspects and certifies the structural work. Where the removed wall meets a shared party wall, common in the borough's terraces across TW11 and SW14, you serve party wall notice on the neighbour first. For listed homes or conservation areas we check whether any external element, such as new glazed doors, needs consent before we begin.
Richmond homeowners choose GS Renovation for open-plan conversions because we deliver the whole job under one roof: engineer-sized steel on padstones and building control sign-off, sympathetic broken-plan and Crittall detailing for period homes, and tidy staged working. More than 30 years on the borough's Georgian and Victorian stock stands behind every knock-through.

FAQ
Expect the figure to track scope rather than postcode. The open-plan conversion elements that move a quotation are span, access and condition, all of which we check at the TW1 property before writing anything down. GS Renovation then itemises labour, materials and the Richmond Council element for your Richmond upon Thames home. Comparing that against another Richmond upon Thames builder is straightforward because every line is visible. Ring 07472 424 226 and we will arrange a free survey at the TW1 property in Richmond upon Thames. 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.
Less than most people expect, because it runs alongside the work. GS Renovation submits the open-plan conversion application, books the Richmond Council inspections and attends them at your TW1 property, so the Richmond upon Thames programme absorbs them. The one thing that does add time is a full plans approval, which we advise on where a listed and conservation-area structure warrants the certainty. Ring 07472 424 226 and GS Renovation will advise which route suits a TW1 home in Richmond upon Thames.
A small, consistent team rather than a rotating cast. GS Renovation employs its own people for the structural element of open-plan conversion and coordinates the following trades at your TW1 home directly. One named manager owns the Richmond upon Thames project, books the Richmond Council inspections and answers the phone. Ask for references in Richmond upon Thames and you will see the same names recur. Ring 07472 424 226 to arrange that. Ask which Richmond upon Thames projects they are on now.
Where the dividing walls are non-structural partitions, usually yes, but the lease and the freeholder's licence to alter come first. In a TW1 flat we confirm with an engineer what is carrying load before agreeing any layout.
The large majority of it. Georgian and Regency townhouses, many listed or within conservation areas make up most of the housing around TW1, so open-plan conversion on them is what GS Renovation does week in and week out rather than occasionally. That familiarity is why a Richmond upon Thames quotation is priced from experience. References across Richmond upon Thames are available on request. Email info@gsrenovationltd.co.uk and we will send addresses of several recent open-plan conversion projects on properties of that age near TW1 in Richmond upon Thames itself.
For the internal structural work, no. Removing a dividing wall is controlled under the Building Regulations, so Richmond Council's building control certifies it, not planning. Planning or listed-building consent only applies to external changes, such as new glazed rear doors, or if your home is listed. We confirm your property's status and handle whichever approvals are needed.
We do not set one. What decides whether GS Renovation takes an open-plan conversion job at a TW1 address is whether we can do it properly and when, not the size of the invoice. Small work in Richmond upon Thames often turns into a longer relationship. Call 07472 424 226 and we will tell you honestly if another Richmond upon Thames trade suits you better. The survey costs nothing regardless. A modest job at TW1 often becomes a longer Richmond upon Thames relationship.
