At one moment one person can only be present at one place. Starting from this observation I develop a hybrid building for complementing programmes, that distributes space in real-time, reacting to the presence of its users at different times. This implies flexibility of the building components in a system of spatial distribution. Using design as a research tool, I carry out design experiments which are informed by rules and parameters corresponding to patterns of use. The design research is embedded in the current social and cultural context of the sharing economy where smart mobile technologies enable the distribution of goods. Here, the distributable good is the temporarily unused space in a building.
