The worldwide economic downturn and trends towards urbanization (combined with desires to live more sustainably) have resulted in a crisis of living: people have to drastically reconsider their living arrangements. There is increasing pressure to provide alternative models to the relatively large, single-family houses with privatized lawns of grass. In response to this shift, students design a home (or homes) for two families on a small lot sized for a typical single-family home. The definition of â€œfamilyâ€ is left to the discretion of each student as is the spatial relationship between the two entities. That relationship could range from providing completely independent living to one where the two co-mingle.
