Icon Background




British Offsite was founded with investment from the Weston Group. Today we are an independent company with two state-of-the-art factories with the capacity to create a complete set of panels for one apartment every 60 minutes.

We're here to give the design and construction industry more choice in how it builds – with the speed, safety, efficiency and environmental gains of our UNisystem and BOS Fitout products.

We know that most people appreciate the significant role offsite construction will play in delivering energy efficient homes faster, to meet government home building and carbon reduction targets. However, they will only transition to offsite when they have full assurances about product quality, design flexibility and compliance with the various required accreditations.

We deliver on all these criteria to the highest standard and have extensive first-hand experience of successfully managing the transition to MMC. We have prototyped over 600 properties for Weston Homes with many more in the pipeline.

We have absolute confidence that the experience you have of our products and services will convert you to our hybrid manufacturing and construction solutions for all your future developments.

Born to build

We were developers before we became manufacturers and remain fully committed to our contribution to the housing industry. We understand the challenges the construction industry faces and maintain a developer’s mindset as we produce offsite manufacturing solutions and services that help designers and developers achieve their vision and goals.

Champions of Precision

We’re bringing the best of automotive manufacturing and the logistics industry to construction, to change how Britain builds. Our UNisystem products consolidate on the production line the work of up to five trades, helping to reduce risks and delays on site and delivering consistently high quality products, down to the finest detail. Our internal modules, for bathrooms, kitchens and bedrooms are equally precise, high quality products that can be produced in volume at high speed.

Proudly British

British Offsite is part of the new high-tech manufacturing sector in the UK, bringing new capabilities and skills to the construction industry. We are helping create a next generation of advanced engineers, manufacturing and construction experts. We are far from insular, we bring in the best materials from around the world to manufacture our products, and seek insights from any and every sector that will enhance what we do. For us, being British means being outward looking, innovative, trustworthy and 100% committed to advancing skills, housing and manufacturing in the UK.

Sustainability & Environment


Steel is 100% recyclable without any loss of quality and today, on average, new steel products contain 37% recycled steel. We’re working with our international supply chain to increase this percentage and ensure our light gauge steel products are among the most sustainable in our industry.


We use durable packaging to protect our products while in transit, which is strong enough to reuse multiple times, reducing the overall volume of packaging we need. Our packaging is 100% recyclable so even when it’s no longer suitable for use, none of it needs to go to landfill.


Our precision, just-in-time manufacturing methods, utilising state-of-the-art machinery, enable us to optimise the use of raw materials, reducing the amount that goes to waste and the overall volumes we need. We’re committed to reusing or recycling our waste as far as possible to minimise the amount we send to landfill.


Energy efficiency is a key consideration as we continue to invest and grow, to make sure we’re playing our part in limiting global warming. Both of our factories have solar panels on the roof. We continuously collaborate with our supply partners to reduce our energy footprint at all stages of production and to develop more energy efficient manufacturing equipment.
