In contrast with more homogeneous environments, we also sometimes noticed interesting variation within the homes we studied. For example, sustainable “green homes” designed to take advantage of sun and wind for heating and cooling have strong temporal variation based on natural forces [ 9]. As another exam-

ple, many Jewish households use technology to help them observe the Sabbath as a day of rest, providing a completely different experience from the rest of the week [ 10]. While these variations are associated with specialized purposes, they inspired us to consider how other consciously designed variations might mani-

fest themselves in homes for the broader population.

Based on these observations, we introduce the concept of the “heterogeneous home,” a diverse and dynamic domestic environment. In this vision we explore the interaction between technology and architecture in the home and consider how the two can
