Clients of this firm include Fever-Tree, Jeep, the BBC and Boxpark — which is No 36 on this year’s table. Founded in 2013 by former stockbrokers Ben Treleaven, 37, and Gregg Curtis, 38, it converts shipping containers into bespoke spaces such as cafes, bars and offices at its factory in Truro. It also repurposes the containers into residential accommodation, ranging from apartments to three-bedroom homes. Last year it completed a 60-unit project for Ealing council in west London, which was constructed, fitted and finished in just 24 weeks. Sales grew to £5.6m in the year to September, thanks in part to a merger with sister company CargoTek.
