The Special Interest Group in Urban Settlement (SIGUS) links housing and community interests in the Department of Architecture and Department of Urban Studies, focusing on developing areas worldwide. SIGUS explores the new professionalism emerging for architects and planners, and concentrates on service, participation and non-traditional client groups. We offer workshops and short courses, and carry out research and outreach programs stressing participatory methods in promoting affordable and equitable housing. Established in 1984, SIGUS grew out of the rethinking of method, practice, and teaching driven by the rapidly expanding informal sector in both developing and developed countries.
