In dwelling construction four types of building activity are distinguished:

- new construction: the erection of an entirely new structure, whether or not the site on which it was built was previously occupied;

- restoration: repairs by which at least one dwelling or other structure is effectively reinstated and where substantial parts of the existing structure are used;

- extension: the enlargement of buildings by which space is added;

- conversion: structural changes carried out within a building.
