Our Knock Through Process
At KJL Builders, we follow a clear and structured process to make sure every wall is removed safely and legally, from first consultation to final finish.
Initial Consultation
We visit your property to discuss which walls you'd like removed and what you want the finished space to achieve.
Structural Assessment & Design
A structural engineer assesses the wall and calculates the correct steel beam specification. We liaise with architects and building inspectors throughout, and can source these professionals for you if you don't already have your own.
Detailed Quotation
You'll receive a clear and transparent breakdown of costs, including the steel beam, labour and timelines. We don't take any payment until the steel beam has been installed and the building inspector has been out to inspect and pass it off.
Building Control Application
We submit the structural calculations and plans to building control for approval before any wall removal begins.
Wall Removal & Temporary Support
The wall is carefully removed with appropriate temporary propping and support in place throughout.
Steel Beam Installation
The steel beam is installed to the structural engineer's exact specification by our experienced team.
Building Control Inspection
The building inspector visits to check and formally sign off the completed steel installation.
Finishing & Making Good
We plaster, skim and finish the area so the new open-plan space looks seamless.

★★★★★
KJL Builders removed the wall between our kitchen and dining room and fitted a steel beam — the whole process was handled properly, with building control involved at every stage. The open-plan space has completely changed how we use the house.
★★★★★
We had a load-bearing wall removed to open up our lounge and kitchen. The team explained the structural side clearly, dealt with the building inspector directly, and the finish was excellent.
★★★★★
Fantastic job removing our chimney breast and installing a steel beam. Everything was signed off properly by building control and the wall was made good so you'd never know it had been there.

Removing an internal wall usually doesn't require planning permission, as it's an internal alteration rather than development. However, if the wall is load-bearing, you will need building regulations approval — we handle this for you.
