Ross House, Melbourne

Ross House is the only self managed and community owned not for profit building in Australia. The greening of Ross House aligns with both the owners and tenants’ vision for social and environmental equity and sustainability. Because the building is both heritage listed and owned by a not for profit organisation, resourcing the building retrofit is particularly challenging.
