About our through-lounge knock-throughs service in Canterbury
We carry out through-lounge knock-throughs in Canterbury, covering the CT1 and CT2 postcode districts. Our coverage runs across Kent, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
Many period terraces and semis were built with a front parlour and a back sitting room divided by a solid brick wall. Opening them into one through-lounge brings light from both ends of the house, but that wall commonly carries the floor joists, the wall between the bedrooms above and sometimes part of the roof load too.
Key points for your project
- 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.
- Victorian brickwork is usually laid in soft lime mortar and the internal walls may be only one brick thick. The engineer allows for this when designing the bearings, and padstones are often used to spread the beam's load over the weaker masonry.
- 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.
- Chimney breasts on the party wall in each room often sit close to the dividing wall. The beam may need to bear near them or avoid them, so the engineer checks how the breasts and flues relate to the new bearing before the opening width is fixed.
- Minor hairline cracks can appear in plaster upstairs as the structure takes up the new support. This is common after a knock-through and is usually filled at decoration stage, but wider or growing cracks should be reported so they can be checked.
What happens, step by step
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.

Building rules for Canterbury
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about through-lounge knock-throughs in Canterbury
Who approves through-lounge knock-throughs in Canterbury?
Structural work in Canterbury 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.
What happens at the survey visit in Canterbury?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
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.
Do I need a party wall agreement for a through-lounge?
In England and Wales, yes, if the beam end will be cut into the wall shared with your neighbour: a party structure notice must be served at least two months before that work. Your neighbour can consent or dissent. Scotland and Northern Ireland have no Party Wall Act, so title deeds and the general law apply instead.
How long does a through-lounge knock-through take?
The structural part usually takes three to five working days, covering needling, propping, removing the wall, fitting the steel and packing it. Party wall notice periods, plastering, period repairs and drying time sit around that, so the overall timeline depends mostly on notices and the finishing work.
