In the strata world there is much to be confused about. The use of the term ‘strata’ itself is curious. Strata are the plural of stratum, the geological formation. It also has distinct meanings in the ecological and sociological worlds. Broadly it connotes layers, portions or divisions hence its application in Australia to the subdivision of land, buildings and airspace to separately titled property and shared common property and facilities. We could have used the term ‘condominium’ or ‘homes’ as the Americans do to describe these spaces but instead, we chose a geological term. Now it has stuck, as these linguistic accidents of history tend to do.
