18 Gross floor area is defined in the LEP's dictionary as follows:
Gross floor area means the sum of the floor area of each storey of a building measured from the internal face of external walls, or from the internal face of walls separating the building from any other building, measured at a height of 1.4 metres above the floor, excluding:
(a) the floor area of lift wells on any level and lift towers, motor rooms and stairwells within a basement or above the roof level, and
(b) so much of the floor area of car parking (including vehicular access to that parking), required to meet any requirements of the consent authority, as does not exceed:
(i) a total of 40 square metres in the case of a dwelling house, or
(ii) a total of 20 square metres per dwelling in the case of a dual occupancy, or
(iii) a total of 20 square metres per parking space in any other case, and
(c) storage areas needed to meet requirements of the consent authority, and
(d) plant rooms, garbage areas, switch rooms or the like within a basement.
19 By limiting gross floor area to the sum of the floor area of each storey of a building, any floor area that does not comprise a storey cannot be included in the floor space ratio calculation. Storey is defined in the LEP's dictionary as follows:
Storey means a space within a building situated between one floor level and the floor level above, or the ceiling or roof above, and includes the space within the following:
(a) foundation areas, garages, workshops, storerooms, basements and the like, whose external walls have a height of more than 1 metre, as measured from the ground level of the lowest point on the site,
(b) an attic within a residential building, but only if:
(i) the roof of the attic is pitched from more than 300mm above the floor of the attic or at an angle of more than 35 degrees, or
(ii) the area of the attic exceeds 60 percent of the floor space of the floor level below.
20 Plainly, the proposed basements comprise spaces within a building situated between one floor level and the floor level above, or the ceiling or roof above. However because the definition provides that such spaces include basements and the like, whose external walls have a height of more than 1 metre, as measured from the ground level of the lowest point on the site, I accept that basements that do not have a height of more than 1 m above ground level do not comprise a storey.
