Open-plan kitchen knock-throughs in Barnet

Why do people in Barnet choose open-plan kitchen knock-throughs?

When a Barnet 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.

Parents across Greater London 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. We cover all of Barnet, including the EN5 postcode district, and travel out to neighbouring towns across Greater London.

What should you budget for open-plan kitchen knock-throughs in Barnet?

Typical open-plan kitchen knock-throughs prices for homes in Barnet, including VAT and adjusted for London. Your own figure depends on the size of the kitchen, the layout and what is moving. Prices in London usually run above the national guide, mainly because labour and parking cost more.

House types around Barnet and what they mean for a kitchen

In and around Barnet, homes range across Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis. 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 Barnet

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 Barnet homeowners

Keep the completion certificate somewhere safe after the work, as a buyer's solicitor will usually ask for it when you sell your Barnet home.
If your Barnet home is leasehold, ask the freeholder for written consent before any structural work is designed or booked in.
Before asking for prices for your Barnet home, look upstairs: a wall directly above the one you want removed is a strong sign it is load-bearing.
Think about fire escape if the kitchen will open onto the hall and stairs, particularly in homes of three storeys or more.

Questions about open-plan kitchen knock-throughs in Barnet

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

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

Which parts of Barnet do you work in?

All of them. Our Greater London coverage takes in the whole of Barnet, including the EN5 postcode district, as well as surrounding towns such as East Barnet. If you are unsure, send us your postcode.

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.

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.

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.
