Our process
Initial discussion and site visit
We meet on site, review the objective and what's already in place, and understand what is fixed and what is still being shaped.
Design review, budget and scope
We contribute buildability input, identify structural risks early and confirm scope. Older or out-of-true buildings get their assumptions checked before pricing.
Pre-start planning and procurement
Long-lead items like structural steel are ordered early. Sequencing is locked in before site starts, with access and temporary works planned around occupied areas.
Live construction and structural works
Site and project managers lead delivery with direct labour on the core works. Structural changes are coordinated tightly with the engineer and building control.
Completion, snagging and handover
We finish properly: completing finishes, working through snagging, and handing over clean and ready to use.

Yes. We regularly undertake structural alterations, including openings, reconfigurations and works involving structural steel, in coordination with the design and engineering team where required.
Yes. Many extension and alteration projects are carried out while the property is still occupied. We plan carefully around safety, cleanliness, access and day-to-day disruption, and our teams are used to working around people who still live or work in the building.
It depends on the size and complexity of the scheme. Smaller structural phases can run over a few weeks; larger multi-month extension projects are common. The honest range is set at pre-start planning.
Yes. We are happy to get involved before the design is finalised. We can work alongside your architect, designer or engineer and contribute buildability input, programme thinking and practical guidance as the project develops. Getting a contractor involved early often avoids costly redesign later and helps ensure the project is priced and planned on realistic assumptions from the start.
