Management of minor buildings. This class describes those objects which complete the definition of buildings but which are not real and proper buildings, either due to construction materials and unstable nature, due to dimensions and non-autonomous intended use, or finally due to structural deterioration and discontinuation of each function. The class assumes the geometry from the volumetric units of which it is composed. In general, these minor buildings are described in this class that participate in the definition of the anthropized territory as constructions that integrate and support the built environment and human activities, characterized by the non-continuous permanence of people.
