Calldene Structural Timber Solutions, one of the South East’s most experienced structural timber engineering specialists, has completed the latest investment phase at its Dover Trussed Roof Company site with a £60k roof extension to increase production capacity and support truss assembly – resulting in strengthened service for customers across the region.
Fully operational from February 2026, the expansion is set to increase product flexibility and scope, benefiting customers in Southern England served by Calldene’s Canterbury and Lancing operations. In many cases, the additional capability will also reduce the need for ‘two-piece’ frames, helping to cut costs and delivery times while improving structural integrity and installation efficiency for clients.

By increasing ceiling height to an existing production facility, the investment provides a dedicated space for truss assembly, enabling more efficient use of the current building footprint. This intelligent engineering boosts manufacturing capabilities by improving assembly capacity and increasing Calldene’s overall production output by 20%.
Les Fuller, Managing Director at Calldene Structural Timber Solutions, said:
This investment is about making it easier for our customers to get what they need, when they need it. By increasing capacity at our Kent site and improving how we manufacture and deliver, we’re strengthening our ability to support projects across Southern England with reliable lead times and a consistently high level of service.
By continuing to invest in its regional operations, Calldene Structural Timber Solutions is reinforcing its commitment to supporting customers across the South East, strengthening local supply chains and delivering high-quality structural timber solutions backed by long-term investment and reliability.
The building expansion follows Calldene’s recent investment in its first dedicated delivery vehicle, as the business continues to prioritise improvements in capacity, efficiency and customer service. Serving both of the company’s production sites, Dover Trussed Roof Company and Triad Timber Components, this new truss truck improves delivery services and capabilities to customers across Southern England.
