Open-plan kitchen, diner and living conversions in Greenwich. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Greenwich, opening up Georgian townhouses near the Maritime Museum and Victorian terraces in Charlton and Eltham into bright kitchen-diners and knock-throughs. With over 30 years in SE3, SE7, SE9, SE10 and SE18, we combine the structural work with careful finishing, including broken-plan layouts and Crittall dividers.

The compartmentalised layouts of Greenwich's period homes, with their separate front rooms, back rooms and galley kitchens, respond beautifully to opening up. Knocking two reception rooms into one, or joining the kitchen to a rear room to form a kitchen-diner, transforms how these houses live while keeping the character of their cornicing, high ceilings and original detailing intact.
Because the walls being removed are usually load-bearing, every conversion is engineered first: we prop the structure, install a correctly sized steel beam on padstones and demolish in safe stages. Many Greenwich homeowners now choose broken-plan layouts, using a Crittall-style glazed screen to divide the space visually while keeping it light and connected, an approach that suits the proportions of these older rooms well.
An internal open-plan conversion is governed by the Building Regulations rather than planning permission, so the Royal Borough of Greenwich's building control signs off the beam, its bearings and the propping. Planning or listed-building consent only applies to exterior work on a listed property or within one of the borough's conservation areas, which are extensive around central Greenwich and Blackheath.
Where the removed wall or a chimney breast within it ties into the shared party wall, common in the terraces of Woolwich, Charlton and Eltham, the Party Wall Act applies and you serve notice on the neighbour first. We coordinate the engineer, the steel and building control, then handle the plastering, flooring and any Crittall dividers so the finished open space is ready to use.
Greenwich homeowners choose GS Renovation for open-plan conversions because one team owns the whole project. We arrange the structural engineer, size and fit the steel, serve secure building control sign-off, and finish the space, from Crittall dividers to plaster. Tidy working in your occupied period home and 30+ years of local structural experience underpin every job.

FAQ
The method is deliberately dull: measure, scope, itemise. Nothing about open-plan conversion is quoted over the phone for a Greenwich home, because a blind figure is a figure that changes later. We look at the SE3 property, allow for its listed and conservation-area construction, and issue a written quotation. GS Renovation works that way throughout Greenwich and it is why the figures hold. Email info@gsrenovationltd.co.uk with the SE3 address and we will arrange a free survey. 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.
Yes, more often than not. GS Renovation runs open-plan conversion at an SE3 property with dust sheeting, sealed openings and a clear-up at the end of each day, which is what makes living alongside it workable in a Greenwich home. Where the listed and conservation-area layout makes that impractical we say so before you commit. The decision stays yours throughout the Greenwich project. Ask on 07472 424 226 what a listed and conservation-area SE3 property typically means in practice.
You get the Royal Borough of Greenwich completion certificate, the guarantee and a number that still answers. Installations carry a five year guarantee, and if something needs attention at your SE3 property after open-plan conversion is signed off you reach the same people who did the Greenwich work. GS Renovation does not route aftercare through a call centre. Nothing about that is a brochure line. Ring 07472 424 226 whenever a Greenwich issue arises. The guarantee covers Greenwich installations for five years.
Building regulations, principally structure. The beam is sized by an engineer and inspected by Royal Borough of Greenwich before it is concealed. Fire separation also matters where the Greenwich conversion opens a stairwell, because escape routes must stay protected under Part B.
Rarely, because we expect what the stock throws up. Georgian and Regency townhouses, many listed or within conservation areas bring aged materials, uneven floors and occasional unauthorised previous work, none of which stops open-plan conversion at an SE3 address but all of which affect the programme. GS Renovation allows for them in the Greenwich quotation. Royal Borough of Greenwich inspects the structural work either way. GS Renovation will happily describe what open-plan conversion usually reveals once an SE3 property in Greenwich is opened up properly on site.
In most cases, yes. Internal open-plan conversions are controlled under the Building Regulations, so the Royal Borough of Greenwich's building control, not the planning department, signs off the steelwork. Planning or listed-building consent is only needed for exterior changes to a listed home or within a conservation area. If a shared party wall is affected, we also serve the required party wall notices.
Almost certainly. The open-plan conversion patch extends well beyond Greenwich and the SE3 area, and what matters is whether GS Renovation can survey the property, run the programme and return for aftercare properly. Most of Greenwich and the surrounding South East London qualifies. Email info@gsrenovationltd.co.uk with the address and we will give you a straight answer. Nothing is owed for the SE3 visit either way. Snagging afterwards is handled by exactly the same team that actually built it.
