Open-Plan Conversions Wanstead

GS Renovation creates open-plan living in Wanstead's period homes, turning the divided rooms of bay-fronted Victorian and Edwardian terraces into bright kitchen-diners and knock-throughs. We open up these houses from Wanstead to Woodford and Ilford without ever compromising what holds them up.

In Wanstead, 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 Wanstead: 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 Wanstead 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 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.
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 conversions in Wanstead terraces

The classic Wanstead conversion joins the two ground-floor reception rooms into one long space, or opens the kitchen into the rear closet wing to make a proper kitchen-diner. Because the dividing spine wall is load-bearing, the knock-through relies on a steel beam sized by an engineer to carry the floor and wall above across the new opening, bearing onto padstones at each side.

Not everyone wants a single vast room. Broken-plan layouts keep a sense of separate zones using a part-height wall or a Crittall-style glazed divider, which suits the proportions of a period terrace and keeps light moving through. We build to the engineer's design either way, prop the structure while the wall comes out in stages, then set and level the steel before the load is transferred onto it.

Housing in Wanstead

By the valuation list's count, Wanstead holds about 4,680 homes, 69% houses and 31% flats; by age, 43% were built before 1919, 20% between the wars and 36% since 1945. 36% of homes here are terraced; opening up a terrace in Wanstead usually lands one beam end on the party wall.

Listed and locally listed checks before a Wanstead knock-through

An open-plan conversion is internal work, so on an ordinary Wanstead house it never touches planning. The exception is a listed building. The Redbridge Local Plan counts over 200 statutory listed buildings in the borough. In one of those, taking out an internal wall is very likely to affect the building's character, so it needs listed building consent as well as building regulations approval. Redbridge does not let a statutory listed address use its standard duty planner service. The advanced service is open to it, and the written advice statement it produces is the document to have before the structural engineer we appoint starts designing the opening.

Local listing is a separate thing and easy to confuse with it. Redbridge reviewed and updated its Local List in 2023, covering locally listed buildings, structures and locally designated areas. A locally listed house does not need listed building consent for an internal knock-through, but the status is weighed in any planning application the wider scheme needs, such as new garden doors on a house in a conservation area. With 43% of Wanstead homes built before 1919, the older houses are the ones to check against both lists before a layout is drawn, since a house added in the review may not show up in the paperwork from its last sale.

Consents for open-plan work in E11

Knocking two rooms into one is internal structural work, so it is controlled under the Building Regulations rather than planning permission. Redbridge Council's building control inspects the propping, the beam and its bearings and issues the completion certificate. Planning is about external changes, which a conservation area controls more tightly; a listed building also needs listed building consent for internal work.

Since the spine wall in these terraces meets the shared party wall with the neighbour, an open-plan conversion that affects that wall is notifiable under the Party Wall Act, and you serve notice on the adjoining owner as building owner, using the drawings we supply. We coordinate the engineer's calculations and book the building control inspections together, so you get an open, certified space with all the paperwork in order.

The file an open-plan job leaves

An open-plan conversion touches more regulations than a single wall removal, and the record you keep should reflect that. Alongside the engineer's calculations and the building control completion certificate there will usually be an electrical certificate covering relocated circuits and lighting, and where the kitchen forms part of the open space, evidence that the extraction meets the ventilation requirements applying to it.

Two more items are specific to open plan. Where a stair now rises from a room rather than a hall, escape and fire detection arrangements form part of what was approved, so the specification of any alarms fitted belongs on the file. And if the beam was fire protected, keep that detail too. In an E11 terrace this whole set is what a buyer's surveyor asks for, and it is far easier assembled as you go. Where a party wall notice was served, keep the award or the written consent with the rest, as that is the item most often lost.

• Level flooring and threshold removal across the whole space
• Zoned lighting circuits and dimming for a multi-use room
• Lighting, heating and electrical reconfiguration
