An alley house is a style of house constructed in an alley that serves the back of other homes rather than a larger residential street. Often, these take the form of terraced houses, which can maximize the use of the spatial limitations of an alley. Alley houses were prevalent in the late nineteenth and early twentieth centuries; their small size made them less expensive in high demand property markets. They have often housed working-class people, immigrants, and/or young families in industrial towns who may have otherwise been excluded by these property markets.[1] Alley houses have declined in their prevalence due to demolitions enacted by governments which were often driven by class prejudice.[2][3] In some regions, more recent trends in housing construction have included homes fronted on alleys. For example, in urban Canada numerous alley-facing homes (known as laneway houses) have been constructed in recent years to meet increasing demand. [4]
