How fast can you produce structural calculations for a Liverpool project?

Once we have all the information, many small domestic jobs in Liverpool are turned around within a few working days. If you already have a builder booked, tell us the start date so we can plan around it.

Can you design RSJs for typical Liverpool wall removals?

Yes. We regularly design RSJs for kitchen knock-throughs, rear openings and through-lounges in Liverpool houses. You receive beam sizes, bearings, padstones and clear drawings your builder can follow on site.

Do you handle Building Control queries?

Yes. We prepare a pack that fits what Liverpool Building Control officers expect to see and we answer their technical questions directly as part of the fee.

What information do you need for a quote?

A short description of the job, floor plans or sketches, a few photos and the property postcode are usually enough for us to give a clear fixed fee for a Liverpool project.

Do you work with local builders and architects?

Yes. We regularly work with builders and designers across Liverpool and nearby towns, and we are happy to speak to them directly about the structural design.

Our Core Services in Liverpool

Steel Beam & RSJ Design

We calculate steel beams for any scenario, from simple door widenings to complex open-plan layouts. Our designs use Eurocode 3 standards to ensure the steel is strong enough to carry the load but efficient enough to fit within your ceiling or floor void.

Local expertise: We account for typical Liverpool constraints, such as concrete floors in city centre flats (Baltic Triangle/Ropewalks) or heavy tiled roofs on 1930s suburban semis.

Load Bearing Wall Removal

Removing a wall changes how your house carries weight. We calculate the correct RSJ size, design the padstones to prevent crushing older brickwork, and provide clear notes on temporary propping for your builder. Includes masonry checks, beam bearing details, and deflection checks to prevent cracks in the rooms above.

Home Extension Structural Design

From single-storey rear extensions to wrap-around and double-storey additions. We design the complete structural shell, including foundations (strip or trench fill depending on ground conditions), steel box frames for bi-fold doors, and roof structures. We calculate lateral bracing to ensure your new extension withstands wind loads and ties correctly into the existing house.

Loft Conversion Calculations

We design the structural upgrades needed to turn an attic into a habitable room. This includes sizing new floor joists to reduce bounce, designing ridge beams for hip-to-gable conversions, and specifying steels to support dormer windows. We have extensive experience with Liverpool’s Victorian cut roofs, detailing exactly how to support the roof once purlins and struts are removed.

How We Work

Send your details: Email us your architect’s drawings, sketches, or photos of the project area along with the property address.

Get a fixed quote: We review the job and confirm the exact structural scope (e.g., "1x RSJ design" or "Full Loft Pack") and give you a fixed fee.

Design & Calculation: Once engaged (typically 50% deposit), we trace the loads, run the Eurocode calculations, and produce the drawings.

Delivery & Support: You receive a PDF pack ready for Building Control within 24–72 hours. We answer any queries from the inspector as part of the fee.

Frequently Asked Questions

Do you need to visit my house in Liverpool?

Often, no. For most internal alterations, extensions, and lofts, we can work from architectural plans, estate agent floor plans, and clear photographs. This saves you the cost of a site survey fee. If a visit is strictly necessary due to complex structural issues (like subsidence or unusual load paths in older terraces), we will tell you upfront and include it in the quote.

Will Liverpool Building Control accept these calculations?

Yes. Our calculations are presented in a standard format recognized by Liverpool City Council Building Control and private approved inspectors. We design to British Standards and Eurocodes. If the inspector asks for clarification (e.g., regarding ground conditions in Bootle or brick strength in Anfield), we provide the answers as part of our service.

My builder says he knows what steel to use. Do I still need calculations?

Yes. A builder’s "best guess" is not insurance-backed and will not satisfy Building Control. Installing a beam without calculations is a risk—if it deflects (sags) later, it damages your finishes, and you may face legal issues when selling the home. We provide the proof that the design works.

What happens if the ground conditions are poor?

Liverpool has varied soil conditions. For extensions, we specify standard foundations (like strip footings) but include notes on what to do if your builder finds made-ground or soft clay. If specialist foundations (like piles or rafts) are required, we can design these for an additional fee.
