Economic inequality has been increasing in recent decades, and nowhere is this more evident than in cities, where resource shortages and access to services disproportionally affect the most vulnerable and marginalized communities. An accessible and inclusive built environment accommodates the different ways in which people use space in cities. The "Inclusive" principle encourages buildings and space to be used easily, safely and with dignity, by all regardless of age, disability or gender. The sustainable built environment must foster opportunities for all, which can be done by creating more communal spaces with flexible purposes. Affordable and safe residential buildings are also key in the creation of inclusive communities.
