Through-lounge knock-throughs in Canning Town: how it works
Planning through-lounge knock-throughs in Canning Town? Our team covers E3, E6, E7, E13 and E14 and the streets around them. The wider London area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
We plan the steel so the opening suits the room's proportions and keeps period features where you want them, from chimney breasts to cornicing. The survey visit, calculations from a qualified structural engineer, building control, party wall notices through a party wall surveyor where needed, propping, steel and making good are all set out in one itemised written quote.
Worth knowing before you start
- If the house is listed, internal structural alterations need listed building consent as well as building regulations approval. Conservation area status does not usually affect internal work, but flats within converted period houses normally need the freeholder's consent.
- Ornate cornicing often runs around both rooms and stops at the wall being removed. Where practical, the run is extended across the opening by matching the profile, either run in place or cast, so the joined room looks original rather than patched.
- The steel commonly needs fire protection to meet building regulations, usually by boxing it in fire-rated plasterboard and skimming it. In period rooms the box can be finished with a matching cornice so it reads as part of the original ceiling.
- The width of the opening, whether the beam bears into a party wall, and how much period detail has to be restored all affect the price. Lath and plaster repairs, cornice matching and floorboard work are priced as separate lines in the quote.
- With the wall gone, the floorboards on each side may run in different directions or sit at slightly different heights. Matching reclaimed boards can be fitted across the old wall line, or the floor can be levelled for a new continuous finish.
Four stages, one team
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Canning Town
For Canning Town, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Yes. We also cover nearby towns including Stratford, Bow, Greenwich and Barking.
Who approves through-lounge knock-throughs in Canning Town?
Structural work in Canning Town needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Will the ceiling crack when the wall is removed?
Some minor cracking in old lath and plaster ceilings is possible, even with careful propping, because the structure is being disturbed. We prop to spread the load and protect ceilings where we can, and any cracks are filled or repaired as part of making good. Sound plaster normally stays intact.
What happens to the floor where the wall was?
A strip of exposed joists, or a footing in a solid floor, is left where the wall stood. Timber floors are patched with matching or reclaimed boards, and solid floors are filled and levelled. If you are fitting a new floor across both rooms, it is simply prepared level for the new finish.
How wide can a through-lounge opening be?
That depends on what the wall carries and how the beam ends can be supported, and the structural engineer sets it. Many owners go nearly full width, keeping short nibs at each end, while others choose a narrower opening to keep two distinct rooms. Wider spans need heavier steel and sometimes columns.
