ABSTRACT Although household consumption contributes to climate change, it can be challenging to comprehend the consequences and effects from a personal perspective. In this paper, we explore the design of physical data visualisations to promote sustainable practices within households. We conducted 15 household design workshops involving household members to explore physical designs and envision the potential use of physical artefacts in the home to promote sustainability behaviours using five low to medium-fidelity prototypes. The findings from these workshops highlight the need to balance aesthetics, abstraction, and the presentation of actionable information in the design of physical artefacts. Based on our findings, we identify key design considerations for future design: (1) including all household members in the design process to reflect the collective goals and values of the home, fostering a sense of ownership and engagement, (2) considering child-friendly design in physical artefacts to promote awareness, education, engagement, and sustainable values in children, (3) and considering nature-based visuals to reduce the mental burden of information overload.
