Open-plan kitchen knock-throughs in Cornwall
If you need open-plan kitchen knock-throughs anywhere in Cornwall, we survey the kitchen, agree the scope with you and book every trade through to handover.
What prompts open-plan kitchen knock-throughs in Cornwall?
Plenty of Cornwall homes have a small back kitchen beside a dining room that only gets used at Christmas, and joining the two gives one room the household actually lives in.
Parents across Cornwall often want to see the garden and the children from the hob, which a knock-through between the kitchen and family room can make possible.
What do open-plan kitchen knock-throughs in Cornwall include?
After the survey visit we write the scope down. For open-plan kitchen knock-throughs in Cornwall it usually covers:
- Free survey visit to check the wall, the floors above and the services running through it
- Structural engineer arranged to design the beam, padstones and temporary propping
- Building Regulations approval arranged, or a building warrant before work starts in Scotland
- In England and Wales, party wall requirements checked where a beam bears into a shared wall
- Temporary props set, the wall removed and the steel beam bedded on padstones
- Cables, pipes and radiators in the wall rerouted by qualified trades
- Beam boxed in, the opening plastered and the floor joined where the wall stood
- New kitchen fitted once the opening is made good and the structural work inspected

Kitchens in homes across Cornwall
You will find granite and slate cottages, Victorian terraces, post-war bungalows and converted barns throughout Cornwall. Older stone cottages often have a small, low-ceilinged kitchen with uneven walls, while post-war bungalows tend to have a square kitchen beside a separate dining area.
Mains water across most of Cornwall is soft, which is kinder to taps and appliances, so heavy limescale build-up is rarely a problem. Narrow lanes, steep harbour streets and cottages with no parking outside can make delivering long worktops tricky, so delivery day needs planning in advance.
Many older Cornish cottages have thick stone walls that are rarely straight, so units and worktops need scribing to fit and wall units need secure fixings. Owners of holiday lets and second homes often want a hard-wearing kitchen that is quick to clean between guests and simple for visitors to use.
Rules for open-plan kitchen knock-throughs in Cornwall
In England, removing a load-bearing wall needs a structural engineer's design and Building Regulations approval through local authority building control or a registered building control approver. Where a beam bears into a party wall, the Party Wall etc. Act 1996 means serving notice on the neighbours before work starts. If the new open-plan kitchen opens onto the hall and stairs, building control will check the escape route, and homes with a floor more than 4.5 metres above ground may need extra fire safety measures.
Where a cottage is listed or sits in one of the many harbour-town conservation areas, consent may be needed before a new extractor vent is cut through an outside wall.
Before you start
- Check what runs through the wall: sockets, switches, radiator pipes, gas pipes and sometimes a soil stack all need rerouting first.
- Allow time for the engineer's design and approval before work starts, especially in Scotland, where the building warrant must be granted first.
- If a beam will bear into a wall shared with a neighbour in England or Wales, the Party Wall Act may require notice before work starts.
- Find out whether the wall is load-bearing before planning the layout; joists landing on it or a wall directly above are common clues.
- Before asking for prices for your Cornwall home, look upstairs: a wall directly above the one you want removed is a strong sign it is load-bearing.
- Clear both rooms completely before the opening is made in your Cornwall home, and seal doors to the rest of the house with dust sheets and tape.
Questions about open-plan kitchen knock-throughs in Cornwall
How much do open-plan kitchen knock-throughs cost in Cornwall?
Guide prices in Cornwall are about £820 to £2,100 including VAT for removing a non-load-bearing wall and making good. The final price depends on the size of the kitchen and what is moving, and is set out in an itemised written quote.
Do you cover the whole of Cornwall?
Yes. We carry out open-plan kitchen knock-throughs across Cornwall, including Redruth, Falmouth, St Austell and Truro. Every job starts with a free survey visit and an itemised written quote.
Do I need approval to remove a wall between kitchen and dining room?
For a load-bearing wall, yes, everywhere in the UK. In England, Wales and Northern Ireland that means Building Regulations approval through building control; in Scotland a building warrant must be granted before work starts, followed by a completion certificate. A non-load-bearing partition is simpler, although a listed building may need listed building consent and a leasehold flat usually needs the freeholder's written consent.
How can I tell if a kitchen wall is load-bearing?
Usually you cannot be certain by looking. Clues include floor joists landing on the wall from above, another wall directly on top of it upstairs, or the wall running down the middle of the house on its own foundation. A hollow knock is not a reliable test, because some stud walls carry loads. We check at the survey, and where there is doubt a structural engineer confirms it before anything is removed.
When is the new kitchen fitted after a knock-through?
After the opening is complete. The order is propping, removing the wall, setting the beam on its padstones, inspection, then boxing in, plastering and joining the floor where the wall stood. Fresh plaster usually needs three to six weeks to dry before full decorating, though a mist coat can go on sooner, so the units are often fitted while the walls dry and the decorating follows later.
