Open-plan kitchen, diner and living conversions in Catford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Catford, opening up the Victorian and Edwardian terraces of SE6 into bright kitchen-diners and knock-through living areas. With more than 30 years in Lewisham, we handle the structural side properly, from engineer-sized steels to Lewisham building control sign-off, so your period home flows the way modern family life needs.

The classic Catford layout, two reception rooms front and back with a narrow kitchen in the closet wing, was designed for a very different way of living. Knocking the receptions together and opening the kitchen into the dining space transforms how these SE6 homes feel, but the spine wall between the rooms is load-bearing, so a properly sized steel beam has to take over its job.
We tailor each conversion to the house. A full knock-through suits some families, while others prefer broken-plan with a Crittall-style glazed divider that keeps the two spaces distinct while letting light run through. Either way the structural opening is engineered first, and the side return and closet wing are factored into where the beam bears.
Opening up a Catford terrace means installing an RSJ that a structural engineer has sized for the loads above. The beam bears onto padstones at each end, the floor above is propped on Acrows while we remove the wall in stages, and the steel is lifted in and pinned up tight before the props come out, so the house stays stable throughout.
This is Building Regulations work rather than a planning matter, so Lewisham Council's building control inspects the beam and its bearings and issues the completion certificate. Because the spine wall meets the party wall shared with your neighbour, the Party Wall Act applies and you serve notice first, then finish with plastering and making good so the new open space is ready to decorate.
GS Renovation is the single team behind your Catford open-plan conversion: engineer's beam design, building control inspections and the build itself, all in-house. We prop and remove safely while you stay in the home, protect floors and keep dust contained, and hand back a clean, certified open space, drawing on 30+ years across SE6.

FAQ
Sometimes, though rarely by as much as people fear. The structural part of open-plan conversion is broadly similar; what differs in a late Victorian and Edwardian Catford house is reinstating cornice, floors and plaster around the SE6 works. Those appear as separate lines on the quotation. GS Renovation has worked on this stock for years and prices it from experience rather than caution. Ring 07472 424 226 and we will describe recent work on similar SE6 properties in Lewisham. 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.
It varies through the year and you will get the real answer. GS Renovation will not open an SE6 property for open-plan conversion until the team can stay on it to the end, which is why a Catford start date is committed rather than provisional. Approvals from Lewisham Council run alongside. Call 07472 424 226 and we will check the next available Lewisham slot. Email info@gsrenovationltd.co.uk with the SE6 postcode and we will confirm the position.
Over 30 years of hands-on experience sits behind every judgement made on your SE6 site. That is our founder's, and it shows in how open-plan conversion is scoped in late Victorian and Edwardian housing before anything is committed. GS Renovation is fully insured, handles Lewisham Council approvals and leaves the Catford site clean each day. Ring 07472 424 226 and speak to the people who will actually do the Lewisham work. Ask to meet the named manager beforehand.
Where the dividing walls are non-structural partitions, usually yes, but the lease and the freeholder's licence to alter come first. In an SE6 flat we confirm with an engineer what is carrying load before agreeing any layout.
Not if the work is planned around them, which is what we do. Cornice, fireplaces, sash windows and original floors at an SE6 property are identified before open-plan conversion begins, and GS Renovation agrees with you which are being retained. Protection goes up before any structural work starts. Reinstatement afterwards is matched rather than approximated in the Catford house. GS Renovation will explain how open-plan conversion protects original detail at an SE6 address in Catford.
In most cases, yes. The wall between the front and rear receptions in an SE6 terrace is load-bearing, so a structural engineer sizes a steel beam to replace it and building control signs off the work under the Building Regulations. As the spine wall ties into the shared party wall, we also serve the Party Wall Act notices before we start.
We are on sites across Catford and Lewisham most weeks, so yes. That proximity affects three practical things on an open-plan conversion project: how fast the SE6 survey happens, how well we know the Lewisham Council process, and how quickly anyone returns afterwards. GS Renovation would rather be judged on those than on a postcode in an advert. Ring 07472 424 226 to check. References are available beforehand. The SE6 survey costs nothing and commits you to nothing.
