audacity.org is a research company for construction industry professionals questioning the assumptions and limitations of British development. Today that means challenging the platitudes of sustainability before they are established in debilitating codes of practice, or as new liabilities actionable in courts of law. The morality of sustainable development suggests a professional duty of care to the environment, which may lead to unfortunate legal innovation and further inertia in the construction industry. This will encourage caution rather than bold experimentation, and is clearly restraining development.
