Subdivision is the division of one lot into two or more lots and/or the amalgamation of several lots into one lot.
There are two types of subdivision:
Freehold (Or 'Green-Title'), where a parcel of land is privately owned in its own right and there isn't any shared land in common ownership
Survey-Strata, where a lot and associated common property are shown on a registered survey-strata plan. A survey-strata lot is a common form of strata that divides a property based on the land only and not by the buildings on a site. A survey-strata may, or may not, have common property (i.e. a common driveway), and like other forms of strata may also have by-laws and a strata company.
