Kitchen-diner knock-throughs in Portslade: how it works

If you live in Portslade, kitchen-diner knock-throughs can usually be planned and priced after a single survey visit. We also work in nearby Brighton, roughly 3.5 miles away. We cover BN3 and BN41, and we fix the price in writing once the layout and scope are agreed.

The wall between a kitchen and dining room is often a structural one, especially in semi-detached and terraced houses where it carries the floor joists for the bedrooms above. Opening it up gives the sociable, open-plan space most families want, but the kitchen brings extra things to plan: pipes, cables, an extractor, and a layout that has to work around the new steel.

Things to plan for

  • Sinks and dishwashers usually sit on an outside wall, but supply pipes and waste runs sometimes cross the internal wall. Moving the sink to an island means planning a waste route with enough fall under the floor, which affects how the floor is prepared.
  • 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.
  • Keep the structural calculations, the building control completion certificate and any gas or electrical certificates together. When the house is sold, the buyer's solicitor will usually ask for evidence that the knock-through was approved and signed off.
  • 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.

How the job runs in Portslade

  1. Survey in Portslade

    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.

  2. 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.

  3. Building control

    We submit a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.

  4. 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 Portslade

For Portslade, building control is provided by Brighton & Hove City Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered

Can I stay at home while the work is done in Portslade?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

How soon can kitchen-diner knock-throughs start in Portslade?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

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.

Who moves the gas pipe for my cooker?

A Gas Safe registered engineer, because work on gas pipework must legally be done by one. If the pipe runs in or near the wall being removed, it is capped or rerouted before demolition starts and reconnected once the new layout is in place. We build this into the programme so it is not left to chance.
