Open-plan kitchen, diner and living conversions in Balham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces in Balham's bay-fronted Victorian and Edwardian terraces, from knock-through kitchen-diners to broken-plan layouts and Crittall dividers. With over 30 years working in SW12, we open these homes up structurally, bring in the right steel and sign the work off with Wandsworth Council building control.

The classic Balham layout, two separate reception rooms front and back divided by the spine wall, no longer suits how people want to live near Wandsworth Common or Clapham Common. Knocking those rooms together, or opening the back reception into the closet wing to form a kitchen-diner, is the most popular change we make in SW12. But that dividing wall is usually load-bearing, so it is a structural job, not a cosmetic one.
A structural engineer sizes a steel beam to replace the wall, and we prop the structure, cut the opening in stages and set the RSJ onto padstones bedded into the flanking walls. If you want to keep some separation, we fit Crittall-style glazed dividers or a broken-plan arrangement so light still travels through the plan while the kitchen, dining and living zones each keep their own feel.
An internal open-plan conversion is governed by building regulations, not planning, so you will not usually need planning permission unless your Balham home is listed or you are altering a protected exterior within a conservation area. Wandsworth Council building control is what matters here, checking the engineer's beam, its bearings and the propping before the opening is closed up and finished.
Because the spine wall is often part of, or bears into, the party wall shared with your neighbour, the work can be notifiable under the Party Wall Act, and you serve notice where it applies. We manage the sequence around your daily life, keep dust contained, and hand over a bright, connected space with the completion certificate that proves it was done properly.
For open-plan conversions in Balham, GS Renovation is one team from first survey to sign-off. We bring in the engineer, size and install the steel, serve any and see Wandsworth Council building control through to completion. We work cleanly in your occupied SW12 home and draw on 30+ years opening up these Victorian and Edwardian terraces.

FAQ
The scope is written out rather than implied. For a Balham property the open-plan conversion quotation lists the structural work, the trades that follow it, the Wandsworth Council inspections and the making good that late Victorian and Edwardian construction usually needs. Site protection and the daily clear-up at SW12 are included as standard. GS Renovation does not treat basic care of your house as an extra. Ring 07472 424 226 and we will confirm what applies at your SW12 address. 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.
That is how we work, and it is deliberate. Splitting a crew across Balham jobs makes every one of them late, so open-plan conversion at an SW12 address is resourced properly from the first day to the certificate from Wandsworth Council. GS Renovation would rather start you two weeks later than leave a house open. Ask our Wandsworth references about it. Ring 07472 424 226 and we will confirm what else is running in Balham or Battersea.
Yes, that is included. GS Renovation submits the Wandsworth Council building control application for open-plan conversion at your SW12 property, books and attends the inspections, and sees the completion certificate through. Where the design needs a structural engineer we appoint and coordinate them. A Balham homeowner is left with the party wall notices to serve, and we prepare those. Ring 07472 424 226 and we will explain the Wandsworth steps. The party wall duty stays with you as Balham building owner.
Often a better one. Part-height walls, Crittall-style glazed dividers and level changes keep zones defined in a Balham home while still opening the space up. The structural work is the same, but the result suits how many households actually live.
Not if the work is planned around them, which is what we do. Cornice, fireplaces, sash windows and original floors at an SW12 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 Balham house. GS Renovation will explain how open-plan conversion protects original detail at an SW12 address in Balham.
Usually yes, but the dividing spine wall in a Balham terrace is typically load-bearing, so a structural engineer must size a steel beam to carry the load once the wall comes out. It is a building regulations job needing Wandsworth Council sign-off, and often a party wall notice too, since the wall is shared. We handle all of it.
There is normally something running in Balham or Battersea. That matters practically: it keeps open-plan conversion materials and labour local to SW12, and it means GS Renovation can attend a Wandsworth site quickly if anything needs looking at. It also means you can ask for addresses. The 31 MyBuilder reviews cover recent work too. Ring 07472 424 226 and we will point you at them. Addresses near SW12 can usually be supplied on request.
