Structural Calculations for Chimney Breast Removal (Certified RSJ Design)

Planning to remove a chimney breast to create more space or improve your layout? Prostructural Design offers safe, compliant, and custom structural engineering solutions. We provide the certified RSJ (steel beam) calculations and detailed drawings required to ensure your home remains stable and secure, and that you achieve Building Control approval without delay.

What Our Structural Engineering Service Offers

Our solutions focus on safely supporting the remaining stack above the removal point using a robust steel beam system, the safest and most compliant method:

• Load-Bearing Calculations: Precise assessment of the weight of the chimney stack to be supported.
• RSJ/Steel Beam Design: Specification of the correct beam size (e.g., UC or UB) required to carry the load.
• Padstone Design: Calculation of the required bearing points and padstone size to distribute the weight safely to the supporting wall.
• Detailed Drawings: Comprehensive engineering documents and drawings for your builder and local authority submission.
• Building Control Support: Documentation prepared specifically to meet Part A (Structure) of the UK Building Regulations.

Why Choose ProStructural Design for Chimney Removal?

We work directly with homeowners, architects, and builders to deliver designs that prioritize structural integrity and compliance. Our aim is to help you enhance your living space safely and confidently.

• Safety First: We exclusively design using the Steel Beam method, avoiding the less reliable Gallows Bracket method which is often rejected by councils.
• Guaranteed Approval: Our reports are prepared by Qualified Structural Engineers and guaranteed to meet all local Building Control standards.
• Quick Turnaround: Efficient design process ensures you get your structural documents quickly to keep your project on schedule.
• Fixed Pricing: Upfront, fixed-fee pricing means no hidden charges or hourly rates.

The Essential Step: Building Control Approval

Removing a chimney breast constitutes a structural alteration under UK law. It is mandatory to notify your Local Authority Building Control (or an Approved Inspector) before starting work.

Note: Building Control will require our certified structural calculations before granting approval. Proceeding without this documentation and final inspection is illegal, uninsured, and highly unsafe.
