Thurston acquires Alsim System Building assets to accelerate growth in modular industry
2 min read | June 2025

We have acquired the assets, intellectual property and customer relationships of Alsim System Building Limited, following its recent insolvency.
The acquisition will immediately complement our product offering and allow it to expand its Cabins division as it seeks to solidify its leadership in the UK modular and portable building sector
This strategic move will diversify our offering, enabling us to manufacture an additional style of temporary living accommodation not currently within our portfolio.
Alsim was established in 1992 and grew into a leader in the temporary living and secure accommodation sector, employing 52 people before experiencing financial difficulties in late 2024.
The acquisition of Alsim’s assets quickly follows our investment into Storplan, a specialist fabrication business in February this year, which has increased production capacity and unlocked the ability to deliver larger structural steel projects and more complex modular construction schemes.
Matt Goff, our managing director, says: “Alsim has long been respected for its design expertise and customer relationships within the construction sector. By acquiring its assets and IP, we’re not only strengthening our own technical capability but also reinforcing our position as a trusted, forward-thinking off-site manufacturer.
“This acquisition enables us to support Alsim’s existing customers with confidence, while enriching our design library and expanding the breadth of solutions we offer. Strategic moves like this are fundamental to Thurston’s growth — we’re actively seeking further opportunities to diversify, scale our capacity, and enhance our expertise to better serve a growing client base and cement our leadership in the modular industry.”
