Open-plan kitchen knock-throughs in Hampton

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

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.

If your Hampton 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. Hampton sits about 12 miles south-west of Westminster, and our Greater London coverage takes in everything in between.

What do open-plan kitchen knock-throughs in Hampton include?

Every kitchen is different, so we confirm the scope in writing. Most jobs of this kind include:

New kitchen fitted once the opening is made good and the structural work inspected
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
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
Structural engineer arranged to design the beam, padstones and temporary propping

Local homes and their kitchens

You will find Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis throughout Greater London. 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.

Building regulations, electrics and gas in Hampton

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.

Tips before you start

Plan the heating for your new Hampton kitchen-diner; removing a wall can also remove a radiator, and the larger room may need more heat.
Tell your neighbours early if a beam may bear into a wall you share; in England and Wales a party wall notice may be needed before work starts.
Before asking for prices for your Hampton home, look upstairs: a wall directly above the one you want removed is a strong sign it is load-bearing.
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 Hampton

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

For removing a non-load-bearing wall and making good, budget around £1,000 to £2,600 including VAT in Hampton. That reflects typical costs in London; we confirm the actual figure in writing once we have measured up.

Do you work near Hampton as well?

Yes. As well as Hampton itself, we cover the rest of Greater London and nearby towns such as West Molesey and East Molesey. The process is the same wherever the kitchen is.

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.

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.

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.
