Fast. Flexible. Reliable. Competitive.


Next generation steel frame construction

British Offsite is bringing extra speed, flexibility and reliability to traditional construction with our next generation light gauge steel framing system and infill panels. We’re not reinventing the wheel of construction. We’re making the wheel in a far better way, with the pre-manufacture of more components on our panels to drive productivity.

UNisystemSFS infill panels and our UNisystemLB light gauge steel system are precision-manufactured on our advanced robotics assembly line and arrive on site with the cavity build-up included. Sheathing board, insulation, vapour control layer, cavity barriers, brick-tie channel or façade support, windows and doors can all be preinstalled, combining the work of up to five trades into one panel.

UNisystemSFS and UNisystemLB are tailormade products manufactured to your exact specifications for any scale of building in any sector. Both come with NHBC Accepts certification.

Solutions for every sector






Better building outcomes

With our pre-manufactured panels, we’re bringing streamlined and efficient processes to the construction industry and delivering better building outcomes.

We're filling the skills gap and increasing productivity. Reducing the use of materials and cutting waste. Lowering energy consumption in the process of building and the final built environment. Delivering essential community assets and high-quality homes faster.

Our focus is integrating with traditional construction. Establishing a hybrid approach that supports developers of all sizes and addresses industry challenges.
