GS Renovation creates open-plan spaces throughout Redbridge, opening up the separate rooms of its Edwardian terraces and 1930s semis. Across IG1, IG2, IG6 and E18, our team, led by a founder with 30+ years on the tools, delivers knock-throughs, kitchen-diners, broken-plan living and Crittall-style glazed dividers, all built on steel sized by the engineer we appoint and signed off by building control.
In Redbridge, 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 Redbridge: 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 Redbridge 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 Redbridge 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 for Redbridge suburban homes
Interwar Redbridge houses were designed as a series of separate rooms: a front reception, a back sitting room and a small kitchen, divided by a solid central spine wall. Families in Woodford and Gants Hill now want light-filled kitchen-diners that open onto the generous rear gardens these plots enjoy. Because that dividing wall is typically load-bearing, opening it up is a structural job that needs an engineer, not just a demolition crew.
We can take the whole spine wall out for a fully open ground floor, or keep things broken-plan with a wide supported opening, a retained pier, or a Crittall-style glazed divider that separates the kitchen from the living space while keeping the light and sightlines. Whatever the layout, a steel beam sized by the engineer bears onto padstones and carries the floor and wall above.
Housing in Redbridge
Redbridge counts roughly 108,080 homes for Council Tax; 27% are older than 1919, 34% interwar and 38% post-war, with 36% flats and 64% houses. 42% of homes here are terraced; opening up a terrace in Redbridge usually lands one beam end on the party wall.
Losing the hall in an interwar Redbridge house changes the escape route
34% of homes in Redbridge were built between 1919 and 1939, and in those houses the hall wall is an obvious candidate for removal. Taking it out, so the front door and the stair open straight into the living room, changes how the bedrooms escape in a fire. In a two storey house that is usually manageable, because first floor bedrooms can rely on escape windows of the right size. Where the house already has rooms in the roof, the stair has to be a protected route, which an open ground floor cannot give without a designed fire solution. So the first question in a Redbridge open plan scheme is how many storeys sit above the room, and the steel comes second.
When the layout touches the escape route, the full plans route puts the fire strategy in front of Redbridge building control before any wall comes down. Redbridge says it makes a decision on a full plans application within 5 to 8 weeks, so an open plan scheme with a fire question needs that time in the programme. Starting on a building notice and settling the fire detail on site risks a partition going back up after the kitchen is fitted. Redbridge building control also offers a free pre-application advice service, and that is the place to test an unusual layout, such as a glazed screen round the stair, before the drawings are finished.
Steel, party walls and sign-off in Redbridge
Once the engineer has sized the beam, we prop the structure temporarily, remove the masonry in a safe staged sequence and set the RSJ onto its padstones before transferring the load. In a Redbridge semi one bearing often lands on the party wall shared with next door, so where the work affects that shared wall you serve notice under the Party Wall Act before starting.
Knocking through is controlled under the Building Regulations rather than planning permission, so no planning application is needed for this internal change. Redbridge Council's building control inspects the propping, the beam and the bearings and issues the completion certificate. We handle the engineer, the steel, the building control inspections and the making good, so you get a finished open-plan room from one team.

FAQ
Frequently Asked Questions about Open-Plan Conversions Redbridge
What happens to the open-plan conversion price if the scope changes in Redbridge?
The open-plan conversion price in Redbridge moves visibly when the scope changes, because the quotation is itemised within £3,000 to £8,000 or more (indicative). A change at IG1 is priced against the same lines rather than renegotiated, and any change touching the approvals, such as Redbridge Council building control sign-off of the beam and the Part B escape route, is flagged. GS Renovation issues a written variation and waits for approval.
Can I knock through my Redbridge semi's ground floor without planning permission?
Yes. Knocking through internally is controlled under the Building Regulations, not planning permission, so no planning application is required for a standard Redbridge semi. Redbridge Council's building control inspects and certifies the steel beam instead. Planning only becomes a question if the outside of the house changes, but a listed building needs listed building consent for internal structural work too. We appoint the engineer for the design and make the building control application for you.
Can I open the back of my Edwardian Redbridge terrace into the rear addition?
Usually, and it is often the best space gain in the house. The wall between the middle room and the rear addition often carries the upstairs addition, so the engineer sizes steel for it. The kitchen in the addition is narrow, so a knock-through makes it a proper kitchen-diner. If the steel bears into a party wall, you serve notice on that neighbour first.
Will one open-plan space in my Redbridge house need a new heating layout?
Usually. Radiators that heated two small rooms are often on walls that have disappeared, and one larger volume loses heat differently. A heat loss calculation sets the new radiator sizes, or underfloor heating is laid under a new floor. Pipes are rerouted at first fix, before plastering, so the choice is made before the walls come down.
Should the stairs stay enclosed when I open up my Redbridge house?
In a two-storey house there is more flexibility, but the escape route still needs thought. Building control looks at escape windows from the bedrooms, linked smoke alarms and keeping the kitchen separated from the stairs. In a three-storey house, including one with a loft conversion, Part B requires a fire strategy agreed before the hallway is opened.
What happens to the chimney breast in the middle of the wall I want to open up in Redbridge?
It either stays as a pier or comes out with its own support. Many period layouts put the chimney breast in the dividing wall, so an opening either side of it keeps the stack standing on its own masonry. Taking it out too means the engineer designs support for the stack above, and a party structure notice if it sits in a party wall.
Does letting a Redbridge house to sharers change an open plan scheme?
Two things change. The use: Redbridge's borough-wide Article 4 direction on small HMOs in the C4 use class came into force on 6 December 2019, so turning a family house into a small shared house now needs planning permission. Check the lawful use before designing around sharers. The layout: an open living space changes how several unrelated occupiers escape in a fire, and shared houses carry stricter fire standards, so the fire strategy is agreed before the wall comes down.
Is an open plan layout simpler in a Redbridge house built since 2000?
Sometimes, though not always in the way people expect. 12% of homes in Redbridge were built in 2000 or later, and in those the roof is often carried on trussed rafters that span wall to wall, so an internal wall may carry no roof load. It may still carry a first floor partition or an engineered joist bearing, and it may be a fire rated wall. The structural engineer we appoint checks the original drawings against what is on site before anything is removed.
Why is open plan in a Redbridge flat treated differently from a house?
Because the flat's entrance hall usually does the job a protected stair does in a house. 36% of homes in Redbridge are flats, and removing the hall walls to join the kitchen and living room can leave bedrooms whose only way out runs past the cooker. Building regulations then want a designed fire strategy, which may mean a rearranged plan or sprinkler protection. The lease also needs the freeholder's consent for any structural wall, so both questions are settled before the steel is sized.
