Clause 25M of the KSPO states that, in the 2(d3) zone, the development standards for number of storeys, site coverage, landscaping and building setback are discretionary development standards . Section 79C(2) of the Act explains what non-discretionary development standards are:
If an environmental planning instrument or a regulation contains non-discretionary development standards and development, not being complying development, the subject of a development application complies with those standards, the consent authority:
a. is not entitled to take those standards into further consideration in determining the development application, and
b. must not refuse the application on the ground that the development does not comply with those standards, and
c. must not impose a condition of consent that has the same, or substantially the same, effect as those standards but is more onerous than those standards,
and the discretion of the consent authority under this section and section 80 is limited accordingly.
19 Clause 25I(5) identifies the maximum number of storeys permissible in the 2(d3) zone. For sites in excess of 2,400m2 (such as the subject site) the number of storeys is five. Clause 25(K) allows an additional storey for steeply sloping sites (such as the subject site). The proposal complies with cls 25I(5) and 25(K). Given that the number of storeys is a non-discretionary development standard, the Court does not have the power to require the applicant to delete the two top floors. Apart from any merit considerations, I cannot therefore require the removal of the two top floors, as suggested by the objectors.
20 Setbacks from boundaries are, however, another matter. Clause 25L(2) states:
The third and fourth storey of any building on land within Zone No 2(d3) must be set back at least 9 metres from any boundary of the site of the building with land (other than a road) that is not within Zone 2(d3) (emphasis added) .
21 The third and fourth storeys of the proposed building are set back 9m from the zone interface boundary that exists between the subject site and 8 Pymble Avenue. Ms Gordon's recommendations would result in part of the third and fourth storeys being set back by more than 9m. The question is: does the Court have the power to require part of the third and fourth storeys to be set back by about 12m, given that setbacks are non-discretionary development standards?
22 In my opinion, the power exists. If the development standard were 9m, s79C(2) would constrain the Court's discretion to impose a setback that is more onerous than 9m. However, the development standard is "at least 9m", and a 12m setback is not more onerous than a setback of "at least 9m". If my reasoning were wrong, then the words "at least" would have no work to do. In interpreting a planning instrument I must assume that all the words are there for a reason, unless their presence leads to an absurdity. The development standard of "at least 9m" does not lead to an absurdity.
23 I turn to the question of whether, on merit grounds, I should impose Ms Gordon's recommendations. I note that cls 25K and 25L deal with steeply sloping sites and with zone interface, so the makers of the KPSO have already considered this aspect of the site's relationship to No 8. However, No 8 Pymble Avenue is in an especially vulnerable position, more so than the ordinary property on a zone boundary and a sloping site. Apart from slope and zone interface, it is further vulnerable to impact because it is in a hollow and to the south of the proposed seven-level building. If the fourth, fifth and sixth levels were further away from the common boundary, the visual bulk seen from No 8 would be reduced and so would the extent of shadow that falls on the yard of No 8.
