Modular construction firm Thurston Group has acquired the assets, IP, and customer base of Hull-based portable building maker Alsim System Building Ltd, following Alsim’s recent insolvency.
The deal will enable Wakefield-headquartered Thurston to enhance its Cabins division and introduce a new line of temporary living accommodation products to its portfolio, thereby expanding its capabilities in the modular and secure accommodation market.
Alsim, founded in 1992, was a known supplier of temporary accommodation solutions before entering administration in late 2024. At the time, it employed 52 staff and had a presence in sectors requiring secure, short-term living units.
The acquisition follows Thurston’s earlier 2025 investment in Storplan, a specialist fabrication business, which increased the firm’s production capacity and enabled it to deliver more complex structural steel and modular projects.
Thurston, established in 1970, currently operates across four sites in East and West Yorkshire, employing around 380 people. The company serves over 100 clients and is forecast to generate £60 million in turnover this year. The Alsim acquisition is part of its ongoing strategy to diversify offerings, scale up operations, and strengthen its position in the UK modular construction sector.
