The "missing middle" in housing refers to the gap in the housing market between high-rise apartment buildings and single-family detached homes. It focuses on providing medium-density housing options such as duplexes, townhouses, and small apartments.
This type of housing offers an affordable and sustainable alternative that can accommodate a larger portion of the population without requiring large land areas, addressing the needs of growing urban populations.
The missing middle is not specifically about high-rise housing, social housing, or eco-sustainable housing, although these types of housing can overlap with this concept.
