Provisions of the Residential DCP
22 The council's advocate, Ms C Schofield, drew my attention to the fact that DCPs are the focal point for the assessment of applications (Zhang v Canterbury City Council (2001) 51 NSWLR 589). Their provisions should not be lightly discarded; however, they may be varied with good reason.
23 The Residential DCP establishes sub-zones with varying densities. It applies two controls for density: site area per dwelling and Floor Space Ratio (FSR). The site is in sub-zone 3, in which the permissible density is one dwelling per 250m2 of site area. On average, the proposal provides one dwelling per 500m2 of site area; so its dwelling density is about half that allowed.
24 The maximum permissible FSR in sub-zone 3 is 0.6:1. The proposal's average FSR is about 0.5:1, considerably less than that permitted. In my opinion, this fact is relevant to the consideration of non-compliance with other provisions. It suggests that where non-compliances occur, the reason for them is to allow an unusual (or innovative) form of housing, rather than to increase the floor space.
25 Mr Layman states that the key inconsistencies with the DCP are
· the number of storeys;
· wall heights of dwellings;
· inadequate side setbacks including zero lot line; and
· inadequate open space in dwellings 1 and 2.
26 The Residential DCP `establishes a building envelope (though it does not call it by that term) of two storeys with a maximum wall height and a pitched roof at 35o. These are clearly controls for the most common form of housing, which is an apartment building. The proposal fits into the envelope, though it does not have a traditional roof, but rather a sloping wall at the top level. To assess whether there is justification for the variation of the storey and wall height control, two questions should be asked. First, is the impact on neighbours made worse by non-compliance? It is not made worse, as the impact is less than that of the complying proposal of 2006. Second, does the building appear bulkier? In my opinion, it does not. In fact, it appears less bulky, because it is broken up by the gaps between the three dwellings. The fact, that it is less bulky (as against appears less bulky) is attested by the fact that its floor space is less than the DCP permits.
27 I turn to the setbacks. While the proposal does not comply with all the setbacks on the external boundaries, my understanding of Mr Layman's evidence is that he accepts these variations as justified. His objection is to the internal setbacks, or rather lack of them, as the internal walls are built to the boundary. I accept that a three-storey high wall built on the boundary is unusual and should not be permitted where the designer has no control about what happens on the adjoining land. In this case, however, the three dwellings are designed together and the designer has absolute control. The subdivision occurs after the buildings are constructed. Moreover, any purchaser of the dwellings will see that there is a three-storey wall on the side boundary. There is justification for setting aside the control in the DCP, which limits walls on boundaries to 3m.
28 I turn to the inadequate open space. The DCP requires 55% of the site as landscaped area. Dwelling 2 exceeds the requirement, while Dwellings 1 and 3 breach it. In total the proposal provides 853m2, which is about 55% of the site area. It is appropriate to assess the proposal as one development, as long as there is no marked imbalance between the areas of open space provided on the various lots. This condition is met.
