I believe that architects can play a vital role in making life better in communities. We can provide well designed spaces and places for people making their everyday life, living conditions, and work conditions better.
As for architects and architecture creating social change, I believe that we can make plans and design spaces for change, but I believe the actual change lies within the community and the people. If the people want the change, and it the spaces are functional for the change, then the communities will benefit from architecture.
