Women's Design Service (WDS) “was set up in London in 1984 as a worker's co-operative dedicated to improving the built environment for women...The organisation became a resource and information centre as well as providing pre-feasibility studies for community projects. At this time WDS produced some of their most important work, publications such as It's not all Swings and Roundabouts and At Women's Convenience, which dealt with specific issues such as women's safety in public places, children's playgrounds and the lack of public toilet facilities. This work has left a lasting impact on the built environment in the UK, for example the requirement by law of baby changing facilities is a direct result of the work the group carried out.”
