GS Renovation turns compartmented mansion flats into bright, open living space across Brent, from Kilburn and Willesden to Wembley and Harlesden. We handle knock-throughs, kitchen-diners, broken-plan layouts and Crittall-style dividers, installing the steel the engineer designs where it is needed and leaving the flat signed off by building control.
In Brent, 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 Brent: 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 Brent 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 Brent 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 conversions in Brent flats
Many of the internal walls in Brent's purpose-built period flats are non-structural partitions, which makes open-plan living very achievable once an engineer confirms which walls carry load and which do not. A knock-through between a cramped kitchen and a separate dining room can create a single sociable kitchen-diner, while a Crittall-style glazed divider keeps light flowing yet gives you a broken-plan feel and some separation from cooking smells and noise.
Where the wall coming out is load-bearing, the engineer we appoint sizes a steel beam that bears onto padstones, and we prop the flat above before demolition begins. The wall comes down in staged sections, the beam goes in, and the props come out only once everything is carrying properly. Brent Council's building control inspects the steel under the Building Regulations, so your new open layout is signed off rather than simply knocked through.
Housing in Brent
By the valuation list's count, Brent holds about 135,080 homes, 38% houses and 62% flats; by age, 28% were built before 1919, 32% between the wars and 40% since 1945. Where most homes are flats, opening up a flat in Brent changes its fire escape route, which building control checks.
Open-plan flats in Brent and the escape route through the hall
62% of homes in Brent are flats, and in a flat the wall people most want gone is often the one between the hall and the living room or kitchen. On an upper floor that hall is normally the protected route out in a fire. Opening the kitchen into the living room while keeping the hall enclosed is usually straightforward. Taking the hall into the open space as well changes how the flat is escaped from, and building control will then look for another answer, such as a fire suppression system or an alternative exit, designed to meet the regulations.
That is why the application route matters for an open plan in a Brent flat. Where Brent's own service is used, it takes either a full plans application or, in certain circumstances, a building notice. A full plans submission lets the fire approach be agreed on paper, and Brent aims to respond to it within three weeks. Agreeing it before the strip-out means the kitchen layout, the detectors and any door that has to stay are all fixed first. Finding out on site, with the hall wall already gone, is the slower and dearer way to learn the same thing.
Consents and sound in Brent flats
Opening up a leasehold flat means the freeholder's licence to alter comes first, and in a managed block the managing agent will review the engineer's drawings and set the terms for access and working hours. Sound matters more once walls come down: an open kitchen-diner can carry noise, so we keep the separating floor and ceiling to your neighbours intact and work within the block's building-management rules on acoustic separation.
This is internal work, so it is controlled by the Building Regulations rather than planning permission; a planning application only arises where the outside changes, and a listed home needs listed building consent for internal work too. Where a beam bears onto a party structure shared with the flat next door, the Party Wall Act may apply and you, as building owner, serve notice. We protect communal areas, contain dust and leave a clean, open, signed-off space.

FAQ
Frequently Asked Questions about Open-Plan Conversions Brent
Is the price of open-plan conversion higher in Brent than elsewhere in North West London?
The price of open-plan conversion in Brent is set by the housing rather than the postcode, within £3,000 to £8,000 or more (indicative). Older construction takes more making good than recent work, and access at HA9 affects the labour line. GS Renovation prices the property in front of it, because the protected route from the stairs decides how open the plan can be, rather than applying a Brent multiplier.
Which walls can I remove to open up my Brent flat?
That depends on what each wall is carrying. In Brent's period flats many partitions are non-structural and can come out easily, but others are load-bearing and need a steel beam on padstones to replace them. An engineer inspects first, and Brent Council building control signs off any structural change. We also secure the freeholder's licence to alter before starting.
Why does building control ask for a fire strategy on an open-plan Brent flat?
Because the enclosed hallway is what lets you get past the kitchen and living room to the front door in a fire. Knock those rooms into it and that route is lost. The strategy agreed with building control sets out detection and which doors stay, and it decides where the open plan can go before any wall is touched, which is why it comes ahead of the steel design.
Is a glazed divider a sensible middle way in a Brent flat?
Often. A Crittall-style screen between kitchen and living space keeps the light and sightlines of open plan while holding back cooking smells and noise, and a fire-rated version can help keep an escape route protected. The frame still needs a sound head: where the old wall was structural, the steel goes in first and the screen is fitted beneath it.
Should a Brent open plan join the kitchen to the dining room or the lounge?
In a flat, kitchen to dining room usually works best, because plumbing and extraction stay close to their existing routes and the shared stack. Opening into the main reception gives a bigger room but moves cooking into what was the escape route and further from the ducting. That layout choice comes before the fire strategy and the engineer's drawings.
How are floors levelled after opening two rooms in a Brent flat?
The strip where the wall stood is filled and both floors are brought to one height, which in older blocks can differ by a board thickness or more. Where joists change direction under the old wall, new noggings or plywood carry the join. Any acoustic layer above the flat below is kept continuous, since a gap along the old wall line lets sound straight through.
What stands in the way of joining two reception rooms in a Brent interwar house?
Usually two things. 32% of Brent's homes were built between 1919 and 1939, and in a house of that age the wall between the front and back reception rooms commonly carries the first-floor joists, while chimney breasts may project from the same line. The beam has to clear the breasts or the breasts come out first. The joined room then needs one heating plan, because two radiators and two fireplaces were sized for two rooms.
When should the managing agent of a newer Brent block see open-plan drawings?
Before building control does. 23% of Brent's homes were built in 2000 or later, and a block of that age is likely to have fire safety information written for the whole building, held by the managing agent or the responsible person. Removing the wall between a flat's hall and its living space changes the escape route that information assumes. Send the drawings to the agent early, so their consultant's comments shape the application rather than delay it.
Does knocking through in a Brent conservation area need planning permission?
Not for work wholly inside a house that is not listed. Brent's conservation area article 4 directions bite on the outside, and where one applies, works including removal of chimneys can need permission. An open plan that also takes a stack down therefore crosses that line. Brent has nine Grade II* listed buildings and around 200 Grade II listed buildings, and for those, listed building consent can cover internal walls too.
