Knock-through walls in Solihull

What should you know before starting in Solihull?

Work inside your Solihull home isn't development, so planning permission doesn't apply — the exception is a listed building, where Solihull Council would need to give listed building consent. Structural work, new electrics and drainage changes come under Building Regulations.

Internal alterations to a listed building need listed building consent from Solihull Council.
Keep the completion certificate and engineer's calculations safe, as a buyer's solicitor will ask for them.
Keeping a short section of wall at each end can mean a smaller steel and a lower cost.

Which option fits your home?

Wide opening instead of full removal

Keeping short sections of wall at each end, or a bulkhead above, lets you open two rooms up while keeping some separation and somewhere to put furniture. It can mean a shorter, lighter steel, and it sometimes gives a better result where the two floors are at slightly different levels or the ceilings don't line up.

Non-load-bearing partition removal

Stud or thin block partitions that carry no weight can be removed without steel, once we've confirmed what's above. The work is mostly making good: patching the ceiling and walls, filling the floor where the wall stood, and moving any sockets or switches. It's the quickest and cheapest kind of knock-through.

Knock-through walls in Solihull: common questions

How long does a knock-through take?

Most take 1–2 weeks on site. The steel usually takes one to two weeks to make after the engineer's calculations are approved, so allow three to five weeks from instruction to finished walls. The wall removal and steel installation themselves typically take two to four days; plastering, drying and refitting sockets take up the rest.

Do you cover the whole of Solihull?

Yes — we cover Solihull from our West Bromwich base, including Birmingham, Warwickshire and Sandwell. Call 0800 088 6248 or send the form on this page to book a free survey.

Will I get a certificate for the steel beam?

Yes. When building control is satisfied, it issues a completion certificate for the work, and you should keep that with the structural engineer's calculations. A buyer's solicitor will ask for both when you sell, as unapproved wall removals are a common problem in house sales. Steel and other products carry their manufacturers' terms, which are set out in your quote.

Does Solihull Council need to approve my knock-through?

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 Solihull Council or a registered building control approver.
