Options to consider in Longbridge

Through-lounge

Joining the front and back reception rooms gives one long room with light from both ends. The wall between them is often load-bearing, and on some houses a chimney breast sits nearby, which needs its own support if it's removed. A partial opening with nibs left either side can be a good compromise on cost and structure.

Load-bearing wall with a steel beam

Where the wall supports floors, other walls or the roof, a structural engineer sizes a steel beam and the padstones that carry its ends. Temporary props hold everything up while the wall is removed and the beam goes in. The steel is then boxed in with plasterboard, usually fire-rated, and skimmed so it looks like part of the ceiling.

Knock-through walls in Longbridge: common questions

Should I do the knock-through before a new kitchen?

Yes, the structural work comes first, but plan both together. Knowing the kitchen layout tells us where the steel can sit, where lights and sockets should go, and whether radiators need to move. Doing the wall and kitchen as one project avoids re-plastering twice and means the floor can run through in one go.

Do you cover Longbridge?

Yes. Longbridge (B31, B38) is about 8 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

How much does it cost to knock through a wall?

In the West Midlands, a knock-through typically costs £1,200–£14,000 including VAT where it applies. Removing a non-load-bearing partition is usually £1,200–£2,800. Opening a load-bearing wall of about 3.5 metres between a kitchen and dining room, with an engineer-designed steel, building control and re-plastering, is typically £4,500–£6,800. Decorating and new flooring across both rooms are usually extra.

Will I need permission from the council in Longbridge?

Not for planning — internal work isn't development unless the house is listed. Building Regulations approval is needed for structural work such as removing a load-bearing wall, through Birmingham City Council or a registered building control approver.
