Open-plan kitchen, diner and living conversions in Woolwich. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Woolwich, opening up the bay-fronted Victorian and Edwardian terraces of SE18 with their rear closet wings and side returns. With more than 30 years of structural experience in the Royal Borough of Greenwich, we turn cramped separate rooms into knock-throughs, kitchen-diners and broken-plan layouts that still stand up properly.

The original layout of a Woolwich terrace keeps the front reception, middle room and rear kitchen boxed apart, which is why so many owners want them opened up. A double knock-through into one long reception, a kitchen-diner running back through the closet wing, or a broken-plan arrangement with a Crittall-style glazed divider are all popular ways to make these SE18 homes feel light and connected.
Almost every one of these layouts means taking out a load-bearing wall, so a structural engineer sizes a steel beam to carry the floors and masonry above. The beam bears onto padstones, we prop the structure while the wall comes down in stages, and the steel is set before the props are released, so the opening is created without ever risking the floors above.
An internal open-plan conversion is controlled under the Building Regulations rather than planning, so the Royal Borough of Greenwich building control department inspects the beam, its bearings and the fire and ventilation requirements that come with joining rooms together. Planning only enters the picture for exterior changes in a conservation area or to a listed building, which is a separate question from the structure inside.
Where the beam takes its bearing from the party wall shared with the neighbouring terrace, the Party Wall Act applies and you serve notice before work starts. A Crittall glazed screen or a retained nib can keep some separation while still feeling open, and we build in the fire protection and any acoustic detailing the new layout needs, then arrange the building control sign-off that completes the job.
Woolwich homeowners choose GS Renovation for open-plan conversions because one team designs and builds the whole thing: an engineer sizes the steel for your knock-through or kitchen-diner, you serve any party wall notices on the neighbouring terrace, and Greenwich building control signs off the beam and fire safety. You also get careful propping, tidy working and over 30 years of local experience.

FAQ
It covers the whole job through to sign-off. The document lists the structural work, the trades that follow, the Royal Borough of Greenwich inspections and the making good at the SE18 property, with the engineer's fee shown where open-plan conversion needs a design. Site protection and the daily clear-up are included. GS Renovation issues it in writing so a Woolwich homeowner has something to hold us to. Ring 07472 424 226 for a sample Greenwich layout before the SE18 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.
Structure first, then services, then finishes, with the Royal Borough of Greenwich inspections fixed between them. That sequence is what stops trades undoing each other on an open-plan conversion job at an SE18 address, and it is written into the programme GS Renovation issues with the quotation. Your Woolwich project is updated against it weekly. Nothing is concealed anywhere in Greenwich before it has been inspected. Ask GS Renovation on 07472 424 226 for the written SE18 programme before you commit.
Yes, fully insured, and we will show you the certificate before work starts. GS Renovation carries cover for every open-plan conversion project, whether the property is in Woolwich or over in Eltham, and we are GS Renovation Ltd, company number 14611254. You can check that independently. Ask any contractor quoting for your SE18 home to evidence the same. Email info@gsrenovationltd.co.uk and we will send ours for Greenwich work. The certificate is offered before any SE18 work starts.
Where the dividing walls are non-structural partitions, usually yes, but the lease and the freeholder's licence to alter come first. In an SE18 flat we confirm with an engineer what is carrying load before agreeing any layout.
In most cases yes, provided the structure is confirmed first. Open-plan conversion at an SE18 property of that age is entirely achievable once an engineer has established the load path, and GS Renovation coordinates that before any design is finalised. Royal Borough of Greenwich then inspects the structural stages. Where it is not suitable we will tell a Woolwich homeowner plainly. Email info@gsrenovationltd.co.uk and we will explain what open-plan conversion requires at an SE18 property first.
For the internal structure, no. Knocking through and installing a steel beam is governed by the Building Regulations, so Greenwich building control inspects and certifies it. Planning permission only applies if you also change the exterior in a conservation area or on a listed building. Because the beam usually bears into the shared party wall, you serve party wall notice on your neighbour first.
Yes, SE18 included, along with every other postcode in Woolwich. Open-plan conversion is not priced differently by street, and GS Renovation is usually working somewhere in Greenwich already. Familiarity with the Edwardian bay-fronted houses with generous ceiling heights and long rear gardens around that postcode is what keeps a quotation accurate. Ring 07472 424 226 and we will confirm your address in a minute. The survey that follows is free and carries no obligation. Aftercare and snagging visits across Greenwich are just as routine.
