A Business Improvement District (BID) is a specified area where local businesses work together to invest in projects such as improving the local environment and public realm. The Victoria BID was launched in 2010. Our brief included looking at areas within Victoria that could be transformed ‘from grey to green’ – i.e. projects to improve air quality and introduce urban greening. Projects included a planting scheme outside the Queen’s Gallery, a ‘rain garden’ outside John Lewis HQ and several new roof gardens above offices. We hope that the combination of these projects will result in a net gain in biodiversity across Victoria.
