Planning through-lounge knock-throughs in Eastbourne
For homes in Eastbourne and the BN20, BN21, BN22 and BN23 districts, we handle through-lounge knock-throughs from survey to sign-off. We also cover the surrounding towns and villages in East Sussex. The beam is sized by a structural engineer and inspected before it is boxed in.
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.
Things to plan for
- 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.
- 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.
- Radiators, pipe runs and sockets on the dividing wall need relocating. Older houses sometimes have heating pipes running under the floor along the wall line, so these are traced and moved by a heating engineer before the wall comes down.
- The structural stage for a through-lounge typically takes three to five working days. Both reception rooms are out of use for that time, so furniture is moved out or stacked and sheeted, and the hallway is kept clear as the main walkway.
- 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.
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.

Building rules for Eastbourne
For Eastbourne, 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.

Questions about through-lounge knock-throughs in Eastbourne
How soon can through-lounge knock-throughs start in Eastbourne?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
How much do through-lounge knock-throughs cost in Eastbourne?
As a guide, budget £2,800–£6,150 including VAT for through-lounge knock-through in Eastbourne, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Can I knock my front and back rooms into one?
Yes, in most houses. The dividing wall is usually load-bearing, so a structural engineer designs a steel beam to carry the floor and wall above, and building control approves the work. In terraces and semis the beam often bears into the party wall, which in England and Wales means serving a party wall notice before work starts.
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.
Is the wall between two reception rooms load-bearing?
In most period terraces and semis it is, because it carries the floor joists and the wall between the bedrooms above. Some later houses have lighter partitions in this position, so the only way to be sure is an engineer's inspection. We arrange this during the survey and design stage.
What happens at the survey visit in Eastbourne?
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.
