Open-plan kitchen, diner and living conversions in Camberwell. Trusted, professional, 30+ years' hands-on experience.
Open-plan living suits Camberwell's Georgian and Victorian homes beautifully, and GS Renovation has spent over 30 years making it happen across SE5. From knock-throughs between front and back receptions to full kitchen-diners and broken-plan spaces with Crittall dividers, we combine engineer-led structural work with a finish that respects the proportions of these period rooms.

The classic Camberwell knock-through joins the two reception rooms of a Georgian or Victorian townhouse into one flowing space. The wall between them is usually load-bearing, carrying the floors above, so it cannot simply be knocked out. A structural engineer sizes a steel beam to bridge the opening, and we seat it on padstones at each end, propping the structure while the masonry comes down in controlled stages.
Extending that same idea to the rear, many Camberwell owners open the kitchen into a side return or garden addition to create a single kitchen-diner. Where a fully open room is not wanted, broken-plan works well: a steel-framed Crittall screen or a part-height wall divides cooking from dining while keeping light and sightlines. Each of these needs its own beam design, and we detail the steel to sit discreetly within the ceiling line.
An open-plan conversion in Camberwell usually removes at least one load-bearing wall, and that is a Building Regulations job, signed off by Southwark Council's building control rather than needing planning permission. Even inside a conservation area, the internal reconfiguration itself is not a planning matter. Planning or listed-building consent only arises if you also change the exterior, such as a side-return roof or new rear glazing on a listed home.
Because these houses share party walls, opening up often means cutting a beam bearing into the wall you share with a neighbour, which is notifiable under the Party Wall etc. Act 1996. You serve the notices and manage the process so relations stay good. The result is a bright, connected ground floor that still reads as a period Camberwell home, delivered by one team from first prop to final coat of paint.
For open-plan conversions in Camberwell, GS Renovation is one team for the whole transformation: engineer's beam design, building control sign-off, structural work and finishing trades. That means no gaps between trades, tidy working in your occupied period home, and a kitchen-diner or knock-through that is both structurally sound and beautifully finished, backed by 30+ years across Southwark.

FAQ
Everything needed to finish the work and get it signed off. The open-plan conversion quotation for a Camberwell home covers labour, materials, the structural engineer where the design requires one, the Southwark Council building control element, and the making good afterwards. Anything genuinely uncertain at the SE5 property is flagged before we start rather than added later. GS Renovation issues it after a free SE5 survey, with no obligation in Camberwell or the wider Southwark. 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.
No, not as one open plan room. Southwark's Householder Development Supplementary Planning Document states that removal of internal walls will not be permitted where it results in the loss of the original plan form. That same Householder SPD states that removal to create an open plan living room, kitchen and dining room will not generally be allowed. Partial removal retaining wall nibs and down stands may be accepted. That is the honest answer before drawings are paid for.
It works, but the gain is length rather than width. The Camberwell Grove appraisal records terraced plots of 5 to 6 metre width based on 18th and 19th century housing patterns, with front setbacks at their minimum of just two to three metres, frequently lighting a semi-basement behind railings. In a plan that narrow the useful move is joining the front and rear rooms, keeping the chimney breast and using a flush beam.
Only with planning permission, because it counts as a basement. Southwark's Householder Development SPD states that planning permission is required for all homes to create a new basement or extend an existing one. It also requires a Basement Impact Assessment, and limits basement extensions to a single storey below ground. Policy P14 of the Southwark Plan 2022 asks for basements without adverse archaeological, amenity or environmental impacts.
Not necessarily, and in the conservation areas the extension is the harder half. The Camberwell Green appraisal applies the same test as Camberwell Grove. Rear extensions should normally be no more than one storey in height, low key and unobtrusive, and full width rear extensions will normally prove unacceptable. Rearranging the rooms that exist, and moving the stair or the utility, can reach the same layout without that planning risk.
Sometimes, though what sits above decides it. Census figures record about nine in ten homes in Camberwell Green ward as flats, with purpose built blocks the largest share. In St Giles ward around eighteen per cent of homes sit in a converted or shared house, against about ten per cent across Southwark. In a converted house the walls above may carry floors, so an opening needs an engineer and the freeholder's consent.
