What prompts open-plan kitchen knock-throughs in South Yorkshire?

Some households in South Yorkshire want a kitchen-diner for having people round, where guests can sit at a table or island while the food is still being cooked.

Parents across South Yorkshire 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 South Yorkshire include?

Here is what usually goes into open-plan kitchen knock-throughs, adjusted to your South Yorkshire kitchen after we have measured it:

  • 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 South Yorkshire

You will find Victorian terraces, former pit village terraces, 1930s semis and post-war council-built houses throughout South Yorkshire. Sheffield's Victorian terraces often have a small kitchen behind the living room, while 1930s semis and post-war houses tend to have a compact kitchen beside the dining room.

Hardness varies across South Yorkshire: Sheffield's supply is generally soft, while some eastern areas are harder, so check with your supplier before choosing a filter. Steep hillside streets and terraces with steps up to the front door can make carrying long worktops and tall units harder, so access is checked at the survey.

Knocking a small back kitchen through to the living room is a common way to make a kitchen-diner in a terrace. Pit-village terraces and ex-council houses often need a full strip-out with new wiring, more sockets and an asbestos check before older floor tiles or boards are lifted.

Rules for open-plan kitchen knock-throughs in South Yorkshire

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.

Parts of Sheffield and Barnsley lie within the Peak District National Park, and listed buildings or conservation areas elsewhere may need consent for new external vents.

Before you start

  • Find out whether the wall is load-bearing before planning the layout; joists landing on it or a wall directly above are common clues.
  • Check what runs through the wall: sockets, switches, radiator pipes, gas pipes and sometimes a soil stack all need rerouting 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.
  • Think about fire escape if the kitchen will open onto the hall and stairs, particularly in homes of three storeys or more.
  • 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.
  • If your South Yorkshire home is leasehold, ask the freeholder for written consent before any structural work is designed or booked in.

Questions about open-plan kitchen knock-throughs in South Yorkshire

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

Open-plan kitchen knock-throughs in South Yorkshire typically cost £760 to £1,900 including VAT for removing a non-load-bearing wall and making good, based on prices in Yorkshire and the Humber. Larger or more involved jobs cost more, and your price is fixed in writing after a free survey visit.

Do you cover the whole of South Yorkshire?

Yes. We carry out open-plan kitchen knock-throughs across South Yorkshire, including Sheffield, Rotherham, Doncaster and Barnsley. Every job starts with a free survey visit and an itemised written quote.

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.

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.
