British Offsite is the creator of UNisystemSFS (non-loadbearing) and UNisystemLB (loadbearing), the most technically advanced, light gauge steel panel systems in the marketplace.
Adaptable to any design vision, our solutions are suitable for housebuilding, mid-rise and high-rise developments, and for the construction of commercial and public buildings.
We manufacture our panels at our flagship factory Horizon, in the heart of Essex, using state-of-the-art robotics, designed with Randek UK. We have the capacity to produce 110,000 lm – the equivalent of 4,000 homes per year. A complete set of panels for one aparatment can be manufactured every 60 minutes.
UNisystemSFS is designed for use in buildings of over six storeys and up to any finished height. The non-loadbearing components, UNipanelSFS (external walls) and UNiwallSFS (internal walls) operate as infill panels, working in conjunction with a loadbearing steel or reinforced concrete structure that delivers vertical load transmission and flooring. Once panels are lifted into place and secured, you have dry building envelopes. Internal fit out can begin on lower floors, while panels are still being lifted into place on floors above.
15 mins
Four UNipanels for a typical apartment can be installed on site in one hour. That's one panel complete with insulation, firestopping, windows and doors installed every 15 minutes.
That's why manufacturing your panels with British Offsite can improve first fork in the ground to first keys handover time by up to 30%.

UNisystemLB (loadbearing) is designed for use in buildings of up to six storeys, with a maximum finished floor height of 18 metres. Every component of UNisystemLB will be familiar. The only difference is we're bringing them together on our automated assembly line, to produce consistent quality panels and deliver dry building envelopes faster.
~2 days
It takes approximately two days to install the panels for a 2B3P semi-detached dwelling, if you're combining UNipanelLB and UNiwallLB with UNifloor. Other floor types e.g. composite floors will take slightly longer.
British Offsite can convert a traditional construction project to a hybrid manufacturing and construction project and deliver to site in as little as 120 days.
