Our attachment to and influence by any given capital system will inform what we design and build. Sustainable projects realistically must consider multiple capital systems (natural, health, intellectual, …) to endure.

It’s not enough to be mindful of biodiversity, for example, if a project is a failure with the public, boring, underused, exclusive and/or quickly replaced.

Any given project, then, should consider:

• natural capital (considerations such as minimising impacts, including physical and figurative disturbance, or creating efficiency to reduce surplus);

• health capital (issues such as stimulation and complexity);

• intellectual capital (promoting visual cues of sustainable design and knowledge, for example);

• moral capital (ideas such as sharing resources, or matching resources to one’s actual needs);

• manufactured capital (seeking out permanence; endurance).
