Matrix Feminist Design Co-operative was a women-only collective/practice centred on bringing issues of gender centre-stage to the design of the built environment. “This included research about gender and space; creating feminist design guidance and support; enabling more women from under-represented groups into construction and architecture; designing building projects for and with women, and co-exploring new building types ignored by a male-dominated profession, such as women's centres and nurseries.” Their work included several built social projects in London UK, technical advice services, feminist research and publication, workshops, symposia, training and pedagogy.
