“Home, sweet home has never meant housework, sweet housework” wrote Charlotte Perkins Gilman towards the end of the 19th century. Although things did not change very rapidly, during the 20th century, the discourse on domestic space became one of the most effective indicators of social change and concerns as revealed by the extraordinary materials from a century of exhibitions on the home stored in the Triennale Milano archives that we have joined together in a new narrative. Today, a new awareness emerging very strongly from the work of architects and contemporary research groups shows how care must be considered a founding action in living and in the process of construction of space and architecture.
