Open-plan kitchen knock-throughs in Roehampton
Whether your Roehampton kitchen is a narrow galley or an open-plan room, open-plan kitchen knock-throughs follow the same careful order: survey, written scope, fit and a final check together.
What prompts open-plan kitchen knock-throughs in Roehampton?
When a Roehampton kitchen is dark because its only window faces a narrow side return, a wide opening into the next room borrows light from the other end of the house.
Plenty of Roehampton 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. We cover all of Roehampton, including the SW15 postcode district, and travel out to neighbouring towns across Greater London.
What is included in the work?
Every kitchen is different, so we confirm the scope in writing. Most jobs of this kind include:
- Structural engineer arranged to design the beam, padstones and temporary propping
- 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
- 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
- Free survey visit to check the wall, the floors above and the services running through it
How much do open-plan kitchen knock-throughs cost in Roehampton?
Use these ranges to plan your budget. They include VAT, reflect costs in London, and are firmed up once we have seen your Roehampton kitchen. Labour in London generally costs more than the UK average, which lifts these ranges a little.

Fitting kitchens in older and newer Roehampton homes
Across Greater London you will often find Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis, and each shapes the kitchen differently. Victorian terraces often have a narrow galley beside the side return, while conversion flats and mansion blocks usually fit the kitchen into a small room or along one living-room wall.
Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day. London's mains water is hard, so limescale builds quickly on taps and boiling water taps, and a scale-reducing filter is worth planning in.
Do you need approval for open-plan kitchen knock-throughs in Roehampton?
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.
Conservation areas are widespread across London, so a new extractor vent on a front wall may need permission, and leaseholders usually need the freeholder's written consent first.
Practical advice for Roehampton homeowners
- Keep the completion certificate somewhere safe after the work, as a buyer's solicitor will usually ask for it when you sell your Roehampton home.
- If your Roehampton home is leasehold, ask the freeholder for written consent before any structural work is designed or booked in.
- Choose the new floor finish before the wall comes out, so the strip where the wall stood can be levelled and covered in one go.
- Allow time for the engineer's design and approval before work starts, especially in Scotland, where the building warrant must be granted first.
Questions about open-plan kitchen knock-throughs in Roehampton
How much do open-plan kitchen knock-throughs cost in Roehampton?
Guide prices in Roehampton are about £1,000 to £2,600 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 all of Roehampton?

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.
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.
