As an urban module aspiring to be equitable and sustainable, the Ideal Sector cannot exist in isolation. It is an essential part of a greater system of common public goods and resources at multiple scales: ecologically, socially, technologically, economically, culturally, spatially, and politically. As a consequence the Ideal Sector is closely integrated with its neighbours and with various larger systems from green networks and regional public-transport systems, to global flows of goods and information and communication.
