100 Liverpool is cleaning up! Winning Building Magazines ‘Project of the Year’, as well as an award at the 2021 Structural Steel Design Awards, to name but a few.
This is high praise for a project that has sustainable design at heart. The mission to drive carbon out of the construction process was realised by utilising 50% of the existing superstructure and 100% of the existing substructure. This has helped pave the way for it to become British Land’s first flagship net zero carbon building, and will no doubt change the landscape of how new and more efficient structures will be delivered in the future. William Hare has undertaken similar structural developments with Battersea Power Station and Triton Square.
100 Liverpool Street was constructed by reconfiguring two existing buildings into a single structure with the new steel frame knitting these together, with an additional four floors on top. This yielded a 40% increase in lettable area totalling 66,000m2.
“The project shows the unique circular economy credentials of steel-framed construction. The steel industry’s fantastic quality control processes and provenance have enabled the retention of much of the existing frame,” explains AKT II Technical Director David Watson.
The collaboration with British Land’s supply chain led to a truly remarkable building. William Hare was appointed to an early PCSA with a remit to add value to, and take risk out of, an extremely challenging project. With the backing of British Land, and working closely with AKTII, William Hare looked at the critical interfaces of the steel frame that knitted the existing structures together, giving advice on a range of elements that helped reduce the costs and weight of the steel frame.
