GS Renovation creates open-plan living across Ealing, turning the compartmented rooms of W3, W7 and W13 terraces into bright kitchen-diners and knock-through receptions. We combine steel designed by the structural engineer we appoint with careful finishing, and can frame broken-plan spaces with Crittall-style dividers where you want light without one vast room.
In Ealing, a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Ealing: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs
- Free site survey at your Ealing address, covering the walls, services and floor levels, and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Ealing Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
- Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.
Open-plan layouts for Ealing terraces
The classic Ealing terrace was built as a warren of small rooms: front parlour, back reception, a narrow kitchen tucked into the closet wing. Opening these into a single flowing space changes how the house lives, but the walls between them are typically load-bearing spine walls. We plan each knock-through around a properly sized steel beam so the structure above is carried, then set the finished floor and ceiling levels to flow cleanly across the old divisions.
Not every Ealing homeowner wants one cavernous room. Broken-plan is popular here: a wide structural opening with a Crittall-style glazed screen keeps the kitchen-diner connected to a snug or study while cutting cooking noise and smells. The engineer sizes the steel for the opening; we build in the padstones and let you choose how open the space feels. The result suits the proportions of a period home rather than fighting them.
Housing in Ealing
Ealing's housing, as the Council Tax list records it, is about 149,900 homes: 46% houses, 54% flats, with 28% pre-1919, 30% interwar and 42% built since 1945. Most homes here are flats, and opening up a flat in Ealing changes its fire escape route, which building control checks.
How Ealing counts an open-plan layout with more than one beam
Ealing's domestic building control charges treat an open-plan scheme differently from a single knock-through. A simple structural opening, such as a simple through lounge, is one item. The installation of a beam combination to form an open plan arrangement is a separate item, charged at the same level as an opening that needs new foundations, piers or columns. Opening the whole ground floor of an Ealing house can need exactly that combination: one beam across the old spine wall and a second picking it up where the kitchen wall once stood.
The practical point is the junction. Where one beam lands on another, the connection is a designed detail, with bolts, cleats or a post, and it is the part the inspector wants to see before it vanishes into the ceiling. Ask the structural engineer we appoint to draw the beams as one scheme rather than as two openings designed a week apart, and describe it on the application as a beam combination. That keeps the application, the charge and the inspections aligned, and stops a second beam turning up later as a variation with its own paperwork.
Getting an Ealing knock-through signed off
Knocking two rooms together is an internal structural alteration, so it is governed by the Building Regulations, not planning permission. Unless your home is listed or you are altering the exterior within an Ealing conservation area, there is no planning application for the internal work. What matters is that the beam, its propping and its padstone bearings are inspected and approved by Ealing Council building control or a registered building control approver.
Because the spine wall you are removing often ties into the party wall shared with next door, we check whether the Party Wall Act is triggered. Where it applies, you serve notice on the adjoining owner as building owner (or your surveyor does), and we give you the drawings it needs. We run the entire conversion under one roof: engineer's calculations, temporary propping and staged demolition, steel installation, then plastering, flooring and any Crittall glazing to finish the space cleanly.

FAQ
Frequently Asked Questions about Open-Plan Conversions Ealing
Does the cost of open-plan conversion rise in a mixed interwar and post-war Ealing property?
Age affects the cost of open-plan conversion in Ealing less than people fear; the structural part is broadly similar, within £3,000 to £8,000 or more (indicative). What differs in mixed interwar and post-war housing is making good plaster, skirtings and floor finishes around the W5 works, priced as separate lines. The sequence also holds: the opening is propped before the wall comes out.
Can I knock my two Ealing reception rooms into one without planning permission?
Yes, in almost all cases. Combining internal rooms is controlled under the Building Regulations rather than planning, so you need Ealing Council building control sign-off, not a planning application. The exceptions are a listed property, which needs listed building consent for internal work too, and exterior changes in a conservation area. The dividing wall is usually load-bearing, so we install a steel beam sized by the engineer, and you serve any party wall notice on your neighbour as building owner.
Does opening up a three-storey Ealing house affect the fire escape?
Yes. On a three-storey Edwardian villa the stairs normally lead down to a protected hallway and out through the front door. Taking the hall wall out means the escape passes through the open living space, so building control needs a fire strategy agreed before approval. We settle that strategy with them first, because it can change the layout, doors and detailing upstairs as well as down.
Will one big open-plan room in my Ealing house be cold?
It can be if the radiators stay as they were. Two small rooms heated separately become one volume with more glass and more wall, so the heat output is recalculated for the new space. Pipework is altered at first fix, before plastering, and underfloor heating is laid before screeding if you choose it.
Is there a halfway option between separate rooms and fully open plan in Ealing?
Yes: broken plan. Keeping short nibs of wall at each end of the opening, or a wide doorway with a steel above, leaves zones for the sofa and table while light passes through. It often needs a smaller beam and less propping, and in a 1930s semi it can keep the chimney breast and the original cornice intact.
What if the floors in my Ealing reception rooms are at different levels?
That is common where a later rear room or extension was added on a solid slab beside the original suspended timber floor. Once the wall is out, the step is visible. The fix is chosen before the new floor finish: packing the timber floor up, lowering the slab where depth allows, or keeping a deliberate step with a nosing at the beam line.
When is the building control charge paid on an Ealing open-plan conversion?
In two parts on a full plan application. Ealing takes only 40% of the charge on submission and invoices the remaining 60% upon commencement of works. So the second payment is triggered by the start on site, not by the finish. Give building control your real start date, and budget for that invoice in the same week the props go up, alongside the steel delivery and the first skip.
Does an interwar Ealing house open up differently from a Victorian one?
It can, because the load path differs. In Ealing 30% of homes were built between 1919 and 1939. In a house of that period the staircase can rise against the wall you want removed, and its trimmer may bear on that wall. The stair has to stay supported once the wall has gone. The structural engineer we appoint traces the stair trimming before the beam layout is fixed, and that can decide whether the stair wall goes or stays.
Is opening up a post-war Ealing house different from a period one?
The walls and floors are. In Ealing 42% of homes were built after 1945, and houses and maisonettes of that age can have concrete floors, blockwork spine walls or floors spanning onto a single cross wall. Each changes what a beam has to carry and where it can bear. The structural engineer we appoint needs to know which floor sits above before sketching an open plan, so lift a board or drill a small inspection hole at survey.
