GS Renovation creates open-plan and broken-plan layouts in Holloway homes, from knocking two receptions into one in a Victorian terrace to opening a kitchen into the living room of a flat. Around Holloway Road and Caledonian Park, with our founder's 30+ years on the tools, we open up these homes with the steelwork and building control sign-off the job demands.
In Holloway, 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 Holloway: 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 Holloway 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 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.
- 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 Holloway terraces
The classic Holloway open-plan project is the through-lounge, taking down the wall between the front room and the rear reception to run light from the street to the garden. Beyond that, owners join the kitchen to the rear room across the side return and closet wing, or use a Crittall-style glazed screen to keep a broken-plan feel that separates cooking from dining without closing the space in.
Because that dividing wall is usually load-bearing in these terraces, an engineer sizes a beam to carry the floor above before anything comes out. We prop the structure, remove the masonry in stages, and seat the RSJ on padstones so the finished opening is clean and square. The result reads as one flowing space while the original floors overhead stay fully and properly supported.
Housing in Holloway
The stock in Holloway runs to roughly 10,640 dwellings, 90% of them flats and 10% houses, built 40% before 1919, 6% between 1919 and 1939 and 50% after 1945. Most homes here are flats, and opening up a flat in Holloway changes its fire escape route, which building control checks.
Getting an open plan Holloway flat approved before walls come down
In Holloway 90% of homes are flats, and opening a kitchen into a living room in a flat changes how you get out in a fire as well as how the room looks. A flat off a shared hall counts as residential premises with common areas, where Islington says a building notice cannot be used, so the new layout goes in as a full plans application. That has an advantage. The approved drawings fix the detection, the door positions and any sprinkler provision before a single wall is touched, and Islington has a statutory obligation to process full plans applications within five weeks, or two months if agreed.
Approval before work also helps with the freeholder. A landlord asked for a licence to alter may want to see the drawings building control has approved, and preparing the application and the freeholder's pack from one set means neither waits for the other. On site in a Holloway flat we build the fire measures first: the new detection, the upgraded doors and any sprinkler head that has to move. Only then does the wall come out, so the flat never sits in a layout the approval did not cover.
Getting it signed off in N7
Opening up a Holloway terrace usually means working into the party wall shared with the neighbour, whether the beam bears into it or a knock-through runs up to it. That makes the work notifiable under the Party Wall Act, so you serve notice on the adjoining owner before starting. We give you the engineer's drawings and a programme early, which keeps the neighbour informed and the schedule intact once the props are in place.
An internal open-plan conversion is Building Regulations work, inspected and certified by Islington Council's building control, and does not need planning permission in an ordinary N7 house. Planning only applies where the outside of the house changes, and a listed building also needs listed building consent for internal work. We bring the engineer's beam design, the steelwork and the building control inspections together as a single coordinated project from start to certificate.

FAQ
Frequently Asked Questions about Open-Plan Conversions Holloway
Is the price of open-plan conversion higher in Holloway than elsewhere in North London?
Work on open-plan conversion in Holloway is priced from scope, so it costs no more than the same house in Highbury, typically £3,000 to £8,000 or more (indicative). Costs rise in period stock and with awkward access, both checked at N7. What neither changes is the order of work: the escape route is resolved at design stage, before the wall comes out. GS Renovation shows each as its own line.
Does an open plan ground floor suit a Holloway terrace?
Often yes, though the hall is usually kept. In your Holloway terrace the two ground floor rooms combine well into a single space running front to back, which brings light through from both ends. Opening the hall as well is a separate question, because the hall encloses the stair and the escape route from the bedrooms. Most schemes here keep the hall and open the two rooms.
What happens to the chimney breasts in an open plan Holloway room?
They usually stay, and they help the room work. Once the dividing wall in your Holloway terrace is removed, the breasts on the flank wall are what stop the space reading as a corridor, and they give two natural focal points. Removing them is a separate structural job requiring support to the stack above. Keeping them costs nothing and gives the long room some structure.
Where does the kitchen go in an open plan Holloway house?
Usually at the rear, where the drainage already is. Putting the kitchen at the back of a Holloway terrace keeps waste runs short and near the existing stack, and leaves the front room as living space away from cooking. Moving it to the front is possible and means running drainage the length of the house with adequate fall. The drainage route decides more than the layout preference does.
Is the room noisier once a Holloway wall is removed?
It usually is, and some of it can be designed out. Taking away a dividing wall in a Holloway house removes mass that absorbed sound and creates one long hard surfaced volume, so conversation, television and kitchen noise all carry. Soft flooring at one end, curtains and considered ceiling treatment help measurably. Where a family uses the two ends differently, that is worth addressing at design stage.
What does a completion certificate for an open plan Holloway flat prove to a buyer?
That the altered layout was inspected and met the building regulations. Islington only issues a completion certificate once the works are satisfactorily complete under the regulations and the fees are paid in full, so an unpaid fee can hold it back after the work has passed. When the flat is sold, the buyer's solicitor asks for it alongside the freeholder's licence, and a removed wall with no certificate can stall a sale while retrospective approval is sought.
Can the hall wall come out in a Holloway flat built in 2000 or later?
Sometimes, but it is the wall most likely to matter. 34% of homes in Holloway were built in 2000 or later, and flats of that age are often designed around a protected entrance hall that the building's fire strategy depends on. Removing that wall means reviewing the strategy with building control and the managing agent first. The outcome can be a glazed fire rated screen in place of solid wall, which keeps the light without losing the protected route.
Is opening up a Holloway house in an article 4 area a planning matter?
Inside, it is a building regulations question only, unless the house is listed. Planning arises where the scheme ends in new external doors or windows. Islington says a house covered by an Article 4 direction needs householder planning permission to install or replace windows or doors on the front of the house, and in its article 4 conservation areas changing external doors and windows may need permission. The garden or street end of the design is therefore checked before the steel is sized.
