According to the United Nations, “the household is a socioeconomic unit (…) based on the arrangements made by persons, individually or in groups, for providing themselves with food or other essentials for living” [1]. The maintenance and functioning of households are determined by specific patterns of consumption, including food, water, and energy (inputs); or patterns of waste, discharges, and emissions production (outputs). Altogether, households’ inputs and outputs generate environmental pressures (with carbon implications), through the consumption of natural goods (water and food) or through the production of environmental threats (sewage, waste, etc). This presentation is particularly engaged on envisaging the relationship between food consumption, waste production and household’s design. The presentation focusses its analysis on the Lisbon Region housing stock, in particular on the kitchen space, while identifying key elements that characterize the evolution of housing design and its metabolic implications. A comparison of past and present households’ patterns of consumption and waste production is determinant to evaluate the evolution of household’s diets, food habits, and environmental pressured related to its metabolism. Moreover, it allows to relate the evolution of such patterns with the evolution of household’s-built space (design) and, determine their related implications on the overall food system functioning. Finally, through a diachronic analysis of ordinary practices of household’s food metabolism and their implications on the household material dimension, we highlight the strategic role of food and water for the revision of contemporary design of household solutions towards future sustainable practices of everyday life.
