Timber Square: Building success with timber workspace

Timber Square is redefining how sustainable workplaces can be designed, delivered, and adapted for the future. Driven by a commitment to minimise whole-life carbon, the project integrates innovative structural solutions, material reuse strategies, and forward-thinking design principles to achieve significant environmental gains whilst delivering best-in-class facilities for a global headquarters occupier. As the UK’s largest commercial scheme to utilise cross-laminated timber (CLT), and the world’s tallest hybrid steel–CLT structure, Timber Square demonstrates the scalability of mass timber in urban construction. The use of approximately 7,000m³ of CLT sequesters substantial embodied carbon while enabling a 30% reduction in embodied carbon and 15% reduction in structural weight compared to a typical new-build construction. Hybridisation with steel—over half of which is produced via recycled electric arc furnace methods—further optimises performance and carbon efficiency. The project also pioneers circular economy principles, incorporating reclaimed steel, retained structural elements, and reused materials across the site. Intelligent engineering solutions, including transfer structures and future-proofed foundations, extend the life and adaptability of both new and existing buildings. Through a “retain, reclaim, build lean, build green” philosophy, Timber Square sets a new benchmark for sustainable commercial development, demonstrating how innovation, collaboration, and material efficiency can transform the built environment.
