A series of interpretative and quantitative questionnaires were conducted on 300 families. For each family, a plan was published in the survey, providing information on where domestic activities take place, and where and when household members are usually located in the house. The interior space was divided into rooms labelled according to a general function, such as kitchen, living room and bedrooms. For each family, the arrangement and disposition of furniture were registered. In each labelled room, it was represented which domestic activities took place, and which family members were usually present at the different times of day (defined as morning, lunch time, afternoon, evening and night).
