What Leeds clients say

Feedback from homeowners and builders using our RSJ design and structural calculations in Leeds.

We removed the wall between the kitchen and sitting room in a stone terrace near Headingley. The RSJ design and calculations were clear and Building Control passed everything without any problems.

Frequently asked questions

Common questions about RSJ design, steel beam calculations and structural calculations for Leeds projects.

How quickly can you provide RSJ design in Leeds?

Most wall removal work and small RSJ design jobs are turned around within 24 to 72 hours once we have drawings, photos and key sizes. Full structural calculations for larger extensions or loft packages usually take five to seven working days.

Will the structural calculations be accepted by Building Control?

Yes. The steel beam calculations and wider structural calculations follow current Eurocodes and are set out in a format Building Control officers across Leeds are used to seeing. If your inspector has any questions we answer them directly.

What do you need from me to start the design?

We need the project address, a short summary of what you plan to do, good photos and basic sizes of the wall or opening. Architect plans, estate agent floor plans or your own sketches all help us plan the RSJ design correctly.

Can you work from photos only or do you need a visit on site?

Many domestic RSJ design and steel beam calculation jobs in Leeds can be handled from photos, sketches and clear measurements. If the structure is complex or access is awkward, we may suggest a site visit or measured survey before we finalise the structural calculations.
