30 In this regard, I note that in the matter of Wehbe the Chief Judge considered at para 64 the effect of various lot sizes in the controls. Then he said:
68 I am not satisfied by this ground for two reasons. First, the second aim of clause 11 is to "improve the residential amenity". That aim is to be achieved, according to the clause, by having allotments of the size specified for the locality. Again, the aim is descriptive of the result achieved by the clause fixing varying allotment sizes depending on the locality of the land to be subdivided and the type of allotment created by the subdivision. For land within zone 2(a) or 2(b) generally north of Mona Vale Road, Mona Vale and east of Chiltern Road, Ingleside, the locality of relevance in this case, the planning policy embodied in the clause is that residential amenity will be improved by fixing a minimum allotment size of 700 square metres rather than the smaller allotment sizes considered to be appropriate for land in the other locality, being in zone 2(a) or 2(b) generally south of Mona Vale Road, Ingleside and Mona Vale.
69 Viewing the second aim this way, granting consent to the proposed subdivision which creates allotments each of 514 square metres does not achieve the second aim of the clause which is to afford to land within zone 2(a) or 2(b) generally north of Mona Vale Road, Mona Vale and east of Chiltein Road, Ingleside, the improved residential amenity that comes from having a minimum allotment size of 700 square metres, rather than the smaller allotment sizes fixed for land in the other locality, being in zone 2(a) or 2(b) generally south of Mona Vale Road, Ingleside and Mona Vale.
31 Similar lot size variations apply in the KPSO, wherein the minimum lot sizes generally apply:
o Res 2( a); 790 sq m.
o Res 2(b); 836 sq m.
o Res 2(c); 929sqm
o Res 2(h); 650 sqm.
32 Presumably these larger lot sizes than the proposed 584/600 sq m size are to maintain and improve the amenity of the existing, predominantly larger lots in this Residential 2(c) neighbourhood. I rely on Ms McCarry's opinion that the proposal does not achieve this.
