Flexible workspace is an effective solution for growing businesses as their needs evolve, but frequent tenant turnover can lead to increased construction waste. The koba @ 100 Barbirolli Square team tackled this challenge directly by pioneering sustainable, circular materials, ensuring business growth aligns with environmental priorities. Circularity was embedded at every stage, from establishing the organisation's strategy through to completion. This approach has resulted in a high-quality space showcasing circular solutions, all documented in a material passport. Consultants Drees & Sommer will explain why circularity was viewed as a crucial component of the business proposition. Cast Interiors will describe how they delivered the circularity objectives outlined in the brief, while circularity platform Madaster will demonstrate how materials passports can both evidence the circularity of selected products and help achieve embodied carbon KPIs.
