PROJECT REPORT: COMMERCIAL BUILDINGS


This represents an approximate 60% reduction compared to the benchmark 1,000 kg CO2


e/m2


for new offi ce buildings


set by the Greater London Authority. Paradise sequesters over 1,800 tonnes of CO2


, equivalent to building 24 homes.


For comparison, Waugh Thistleton’s 5,000 m2


Black & White Building,


completed in 2022, came in at 410 kg CO2


e/m2 .


Reducing whole lifecycle emissions is vital to help buildings underpin national net zero targets, but what about 60, 70 or 100 years down the line? What can be done to ensure that buildings aren’t simply knocked down and sent to landfi ll? An important piece of the puzzle is to design them with a high level of circularity so that structures, products and materials can be easily dismantled and reused at end of life, retaining their value. Paradise’s pioneering approach to

All components were designed for logical and practical disassembly. Achieving this at interfaces between different materials, such as where steel columns interface with CLT fl oor slabs, was a particular challenge. Traditionally, cementitious grout would be used in connections to ensure fi restopping, instead the team looked at alternative options to grouts – ultimately adopting a combination of stone wool and sealants.

design for disassembly required close collaboration between the architects, engineers, and consultants. It hinges on a strategy to exploit dry mechanical fi xings and reversible fastenings, instead of adhesives, that allow components to be easily demounted in the future. About 80% of the structural wood is designed for reuse after the building’s demolition.
