Kitchen-diner knock-throughs in Hemel Hempstead: how it works
If you live in Hemel Hempstead, kitchen-diner knock-throughs can usually be planned and priced after a single survey visit. It sits about 8.8 miles from Luton, which we also cover. We cover HP1, HP2, HP3 and WD4, and we fix the price in writing once the layout and scope are agreed.
We plan the structural work alongside your kitchen design so the beam, any column and the services all land in the right place before units are ordered. A survey visit, engineer's calculations, building control, propping, the steel and making good are all covered in one itemised written quote, with the price fixed in writing once the layout and specification are agreed.
Things to plan for
- Older kitchens can hide asbestos in textured ceiling coatings, floor tiles, boxing around pipes or the backing of old heaters. In buildings from before 2000 it must be identified before the fabric is disturbed, so a survey of the affected area is arranged first.
- In many houses the kitchen and dining room wall carries the bedroom floor joists, and sometimes a bathroom wall above. Lifting a floorboard upstairs to see which way the joists run is a useful first look, though the engineer confirms what the wall actually supports.
- While the wall is out you will usually be without a working kitchen for several days. Many households set up a kettle, microwave and fridge in another room for that period and plan simple meals that need little cooking.
- If the kitchen also opens onto the hallway, the change can affect the escape route from the bedrooms. Building control checks how people would get out in a fire, and smoke alarms, a fire door or other measures may be required as part of approval.
- Where the wall stood there is usually a strip of footing or a change in floor level between the two rooms. It is levelled with screed or timber so one continuous floor finish, such as tiles or engineered boards, can run straight across.
Four stages, one team
Survey in Hemel Hempstead
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Hemel Hempstead
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered
Do you also work near Hemel Hempstead?
Yes. We also cover nearby towns including Berkhamsted, St Albans, North Watford and Harpenden.
What happens at the survey visit in Hemel Hempstead?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Do I need permission from my landlord or freeholder to open up a kitchen?
If you own a leasehold flat, usually yes. The lease will normally require the freeholder's or landlord's written consent for structural alterations, so get that before any work is booked. Freehold houses do not need this, and planning permission is not normally needed for internal changes unless the building is listed.
Should I do the knock-through before or after fitting a new kitchen?
Before. The steel, any column, the floor levelling and the plastering all need to be finished first, so the kitchen fitter works in a dry, square room with services already in position. Fitting units and then taking out a wall risks damage and rework, and the beam position can affect where wall units go.
Can the steel beam be hidden in the ceiling?
Yes, a flush beam can be set into the ceiling void so there is no step between the kitchen and dining ceilings. It needs enough joist depth and more labour to connect the joists to the steel, so it costs more than a downstand. The engineer confirms whether it is possible in your house.
