Open-plan kitchen knock-throughs in Mitcham

When do open-plan kitchen knock-throughs make sense in Mitcham?

If your Mitcham home is an older terrace, the wall between the kitchen and the middle room may well be load-bearing, so an engineer and a steel beam are likely to be part of the plan.

Some households in Greater London want a kitchen-diner for having people round, where guests can sit at a table or island while the food is still being cooked. Kitchens in every part of Mitcham are covered, and the survey visit is free wherever you are in Greater London.

House types around Mitcham and what they mean for a kitchen

The housing mix across Greater London includes Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis, so no two kitchen fits are quite alike. 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.

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. Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day.

Do you need approval for open-plan kitchen knock-throughs in Mitcham?

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.

Worth knowing before the fit

If your Mitcham home is leasehold, ask the freeholder for written consent before any structural work is designed or booked in.
Plan the heating for your new Mitcham kitchen-diner; removing a wall can also remove a radiator, and the larger room may need more heat.
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.
Expect dust and noise for several days; clearing both rooms and sealing doors to the rest of the house saves a lot of cleaning.

Questions about open-plan kitchen knock-throughs in Mitcham

How much do open-plan kitchen knock-throughs cost in Mitcham?

Open-plan kitchen knock-throughs in Mitcham typically cost £1,000 to £2,600 including VAT for removing a non-load-bearing wall and making good, based on prices in London. Larger or more involved jobs cost more, and your price is fixed in writing after a free survey visit.

Which parts of Mitcham do you work in?

All of them. Our Greater London coverage takes in the whole of Mitcham, including the CR4 postcode district, as well as surrounding towns such as Morden. If you are unsure, send us your postcode.

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.

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.

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.
