Open-plan kitchen knock-throughs in Southampton
Homeowners and landlords in Southampton can book us for open-plan kitchen knock-throughs: walls between kitchen and dining room removed, steel designed by an engineer, then the new kitchen fitted.

When do open-plan kitchen knock-throughs make sense in Southampton?
Some households in Hampshire want a kitchen-diner for having people round, where guests can sit at a table or island while the food is still being cooked.
Plenty of Southampton 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. Kitchens in every part of Southampton are covered, and the survey visit is free wherever you are in Hampshire.
What do open-plan kitchen knock-throughs in Southampton include?
After the survey visit we write the scope down. For open-plan kitchen knock-throughs in Southampton it usually covers:
- Building Regulations approval arranged, or a building warrant before work starts in Scotland
- Beam boxed in, the opening plastered and the floor joined where the wall stood
- Cables, pipes and radiators in the wall rerouted by qualified trades
- 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
- Free survey visit to check the wall, the floors above and the services running through it

Local homes and their kitchens
The housing mix across Hampshire includes Victorian terraces, 1930s semis, post-war estate houses and thatched and brick cottages, so no two kitchen fits are quite alike. Terraces in Southampton and Portsmouth often have a narrow back kitchen, while post-war estate houses tend to have a compact rectangular room suited to an L-shape.
Dense terraced streets can be very tight for parking, and New Forest lanes and village roads may limit the size of delivery vehicle. Water across Hampshire is mostly hard, largely from chalk sources, so limescale on taps and boiling water taps is common and a filter can help.
Building regulations, electrics and gas in Southampton
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.
Homes within the New Forest or South Downs national parks, listed cottages and conservation areas may need consent for a new extractor vent or alterations to historic features.
Worth knowing before the fit
- Before asking for prices for your Southampton 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 Hampshire home, and seal doors to the rest of the house with dust sheets and tape.
- Check your home insurance and mortgage terms before structural work in Southampton; some insurers and lenders ask to be told about alterations like this.
- 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.
Questions about open-plan kitchen knock-throughs in Southampton
How much do open-plan kitchen knock-throughs cost in Southampton?
Open-plan kitchen knock-throughs in Southampton typically cost £920 to £2,300 including VAT for removing a non-load-bearing wall and making good, based on prices in the South East. Larger or more involved jobs cost more, and your price is fixed in writing after a free survey visit.
Can you measure up in Southampton before quoting?
Yes. Every quote starts with a free, no-obligation survey visit to your home in Southampton. We measure the room, check the walls, floor and service positions, then send an itemised written quote.
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.
Who designs the steel beam for a knock-through?
A structural engineer does. We arrange the engineer, who calculates the loads and specifies the beam size, the padstones it bears on and the temporary propping needed while the wall comes out. Those calculations go with the Building Regulations application or building warrant. We do not design steelwork ourselves; the work follows the engineer's design and is inspected as part of the approval.
Does knocking through to the kitchen affect fire safety?
It can. If the new open-plan kitchen opens straight onto the hall and stairs, a kitchen fire could affect the escape route from upstairs, so building control, or the building warrant process in Scotland, will check how people would get out. In houses with a floor more than 4.5 metres above ground, usually three storeys or more, extra fire safety measures may be needed. We confirm what applies before work starts.
