25 The DCP Guidelines and Controls: Whilst the council identified G3 and G5, it is important to have regard to the total context and controls:
G1: Existing setbacks on street frontages are to be maintained. Siting and setbacks of structures are to continue the immediate established patterns. Site coverage is not to be disproportional to the adjoining properties. New residential structures are not to be built forward of existing building alignments. Levels established by infill and new residential structures are to reflect ground levels established by buildings in the context of the site. Where the existing ground level slopes and adjoining properties have basement levels, a basement level will be permitted.
26 The other provisions that must be read in the assessment of the application are those under 5.1.6, that is landscaping and private open space. The explanation is:
Paddington's characteristically small allotments with their boundary to boundary buildings provide limited opportunities for ground level open space and landscaped areas. In many instances with residential properties, a very small landscaped area occurs in the street front zone. This area is generally not useable as private open space. At the rear of the residential properties there is a greater scope for useable open space and landscaping.
The objectives are:
1. To promote landscaping that contributes to the character of the conservation area.
2. To maintain an area at the rear of each site which enables planting at natural ground level and assists on-site drainage.
3. To ensure that provision is made for accessible and useable private open space at the rear of premises.
4. To encourage the provision of semi-permeable and permeable areas of open space in rear gardens to assist with on-site drainage.
5. To ensure that the design and use of private open space areas has regard to environmental impact on the fabric of adjoining properties and impact on the amenity of the occupiers of adjoining properties.
6. To ensure that trees and other vegetation do not have an adverse impact on the fabric of buildings and works and have no minimal adverse impact on the amenity for the occupiers of properties.
27 In particular, the one that has been highlighted is:
To ensure that the design and use of private open space area has regard to environmental impact on the fabric of adjoining properties and impact on the amenity of the occupiers.
28 The guidelines and controls for landscaping and private open space state:
1. The required area of private open space for residential properties is to be one-sixth of the site.
2. Onsite detention of stormwater shall be provided by porous and semi-porous services. This should be 50% of the required open space.
3. The area of soft landscaping should be at least 50% of the required private open space.
4. Soft landscaping shall be at existing ground level or at the original garden level.
5. Part of the private open space must be capable of serving as an extension of the dwelling for relaxation, dining, entertainment, recreation and children's play area and should be directly accessible from the main living area of the dwelling. Stairways and ramps may be used to provide access from the building to the open space in cases of sloping sites and grade variations. The raising of open space areas to provide level access from a building may not be acceptable due to the impact on adjoining properties and the significance of the property generally. That is the one that is highlighted for these proceedings.
29 Indeed, I must have regard to a commonsense interpretation of how the provisions are to be read together and not blind adherence to each and every provision to be ticked off as such. In this regard, the Court of Appeal judgment of Zang v Canterbury is of relevance wherein it states:
A development control plan is not an environmental planning instrument. Accordingly, the requirement of s 82, that the consent authority must refuse an application that would result in a contravention of such an instrument, does not apply to a development control plan...nor can such a plan contain a non-discretionary development standard which would take away the consent authority's discretion under 79C...
The consent authority has a wide-ranging discretion. One of the matters required to be taken into account is the public interest, but the discretion is not at large and is not unfettered...DCP is a fundamental element in or a focal point of the decision-making process. A provision so directly pertinent to the application for consent before the council was...was entitled to significant weight in the decision-making process but was not of course determinative.
30 Mr Fotos is of the opinion that the proposal would have detrimental impact in terms of diminishing the heritage value. I will also state in fairness to the respondent that Ms Thom was unavailable to give evidence, but the Court has the benefit of her written comments and her written comments are to the same effect, that the proposed raising of the rear yard would not be sympathetic to the historic conservation area.
