Open-Plan Conversions Islington

GS Renovation creates open-plan living across Islington, opening up the compartmentalised ground floors of Barnsbury, Highbury and Holloway terraces into bright kitchen-diners, and refining the layouts of Clerkenwell's warehouse conversions. We handle the steel and the finishes as one job.

In Islington, 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 Islington: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs

1. Free site survey at your Islington address, covering the walls, services and floor levels, and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Islington Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
4. Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.

Open-plan kitchen-diners in Islington terraces

In Islington's houses, the classic open-plan conversion opens the rear of a Victorian terrace, knocking the kitchen through to the middle room to create one long, sociable kitchen-diner. Because the dividing wall is load-bearing solid brick, this means a steel beam, padstones and a building control inspection, and often a Party Wall Act notice where the wall is shared.

Where there is a side return, we can go further and infill it to widen the space, bringing in light through rooflights and glazed doors, a hugely popular upgrade on the borough's terraces.

Housing in Islington

Islington has about 112,190 homes on the Council Tax list: 43% pre-1919, 4% interwar and 50% post-war, with flats making up 85% and houses 15%. Where most homes are flats, opening up a flat in Islington changes the protected route from the bedrooms to the front door, so building control checks the escape before any wall comes out.

Open plan in an Islington flat is a fire question first

When an Islington homeowner asks for an open-plan layout, the rooms being joined are more often in a flat than a house: 85% of homes in the borough are flats. In a flat the internal hall is normally the protected route from the bedrooms to the front door, and a kitchen opened into the living room can put the cooking area on that route. So the first drawing is not the steel but the escape plan: which doors stay, which rooms become inner rooms, and whether a protected lobby, a fire suppression system or a different layout makes the scheme work under Part B.

Where the flat is reached through a shared entrance, Islington says the building notice route is closed to it, because that route cannot be used for residential premises with common areas. The layout goes in as a full plans application, and Islington Council has a statutory obligation to process those within five weeks, or two months if agreed. We use that window to settle the escape plan with the plans examiner while the kitchen design can still move. Ordering units before the plan is approved is how an island ends up where a door has to go.

Broken-plan options for period homes

Open-plan is not the only route. In Islington's finer Georgian houses, where the reception rooms carry original cornicing and shutters, a broken-plan layout, part-height walls or a Crittall-style glazed divider can open the space up while keeping some separation and the period character.

Whichever route suits your home, we level the floors across the rooms, remove thresholds, and rework the lighting, heating and electrics so the finished space reads and functions as one.

What you give up when walls go

Opening a floor up is not all gain, and it is better to hear that before the wall comes out than afterwards. You lose wall space, which is where the radiators, the bookshelves and the television used to go. You lose doors, so cooking smells and noise reach the whole floor. And you lose a room that can be shut off, which matters more than people expect once somebody is working from home or a child wants somewhere quiet.

There are answers to all of it. A retained pier or a glazed screen keeps some separation while the light still travels. A good extractor deals with the cooking. Underfloor heating or a tall slim radiator frees the wall up. Islington terraces off Upper Street are deep and narrow, so we usually suggest zoning the space rather than emptying it, and we mark the furniture layout out on the floor before anything is demolished.

• Kitchen island services routed through the new floor
• Radiator relocation and underfloor heating in the new layout
