Planning Framework
13The parties agreed that the proposal is not captured by cl 4 'Application of Policy' of State Environmental Planning Policy No 65 - Design Quality of Residential Flat Buildings (SEPP 65), which states:
(1) This Policy applies to development being:
(a) the erection of a new residential flat building, and
(b) the substantial redevelopment or the substantial refurbishment of an existing residential flat building, and
(c) the conversion of an existing building to a residential flat building.
(2) If particular development comprises development to which subclause (1) applies and other development, this Policy applies to the part of the development that is development to which subclause (1) applies and does not apply to the other part.
14However, the parties submitted that the provisions of SEPP 65 and the Residential Flat Design Code (RFDC) are a relevant consideration in this matter, as an objective standard against which the merits of the proposal can be assessed, on the basis that the approved development was assessed with regard to the provisions of SEPP 65.
15The relevant design quality principles of SEPP 65, at Part 2, are context, scale, built form, density and aesthetics.
16The site is within the R4 High Density Residential Zone, pursuant to LEP 2012 and the proposal is permissible with consent.
17The relevant aims of LEP 2012, at subcl 1.2(2), are as follows:
(d) for urban design:
(ii) to promote development that is designed and constructed:
(A) to enhance or integrate into the natural landform and the existing character of distinctive locations, neighbourhoods and streetscapes, and
(B) to contribute to the desired future character of the locality concerned
(e) for amenity:
(i) to maintain and enhance the existing amenity of the local community, and
(ii) to reduce adverse impacts from development on adjoining or nearby residential properties
18The relevant objectives of the R4 zone are as follows:
· To provide for the housing needs of the community within a high density residential environment.
· To provide a variety of housing types within a high density residential environment.
· To allow for increased residential density in accessible locations, while minimising the potential for adverse impacts of such increased density on the efficiency and safety of the road network.
· To encourage innovative design in providing a comfortable and sustainable living environment that also has regard to solar access, privacy, noise, views, vehicular access, parking and landscaping.
19The site is located at a zone interface. The zone to the north and west of the site is the B4 Mixed Use Zone (LEP 2012 Land Zoning Map, exhibit B, vol 2, tab 9, f 81). The properties within the R4 zone and the B4 zone, surrounding the site, have a height limit of 34m (LEP 2012 Height of Buildings Map, exhibit B, vol 2, tab 9, f 82). The properties within the R4 Zone have a maximum FSR of 1.7:1 and the carpark to the north of the site and the childcare centre and semi detached dwellings on the western side of Devonshire Street do not have a maximum FSR (LEP 2012 FSR Map, exhibit B, vol 2, tab 9, f 80).
20The parties agreed that the objectives of the height development standard are a relevant consideration and that the proposal complies with the height development standard. The relevant objectives of the Height of Buildings clause, at subcl 4.3(1), are as follows:
(b) to minimise the impacts of new development on adjoining or nearby properties from disruption of views, loss of privacy, overshadowing or visual intrusion,
(d) to minimise disruption to existing views or to achieve reasonable view sharing from adjacent developments or from public open spaces with the height and bulk of the development,
(e) to set upper limits for the height of buildings that are consistent with the redevelopment potential of the relevant land given other development restrictions, such as floor space and landscaping,
(f) to use maximum height limits to assist in responding to the current and desired future character of the locality,
(g) to reinforce the primary character and land use of the city centre of Chatswood with the area west of the North Shore Rail Line, being the commercial office core of Chatswood, and the area east of the North Shore Rail Line, being the retail shopping core of Chatswood,
(h) to achieve transitions in building scale from higher intensity business and retail centres to surrounding residential areas.
21The relevant objectives of the FSR development standard, at subcl 4.4(1), are as follows:
(a) to limit the intensity of development to which the controls apply so that it will be carried out in accordance with the environmental capacity of the land and the zone objectives for the land,
(b) to limit traffic generation as a result of that development,
(c) to minimise the impacts of new development on adjoining or nearby properties from disruption of views, loss of privacy, overshadowing or visual intrusion,
(d) to manage the bulk and scale of that development to suit the land use purpose and objectives of the zone,
(i) to achieve transitions in building scale and density from the higher intensity business and retail centres to surrounding residential areas,
22Clause 4.6 of LEP 2012 provides flexibility to the application of certain development standards to particular development. The applicant must provide a written request that seeks to justify the contravention by demonstrating the following, at subcl (3):
(a) that compliance with the development standard is unreasonable or unnecessary in the circumstances of the case, and
(b) that there are sufficient environmental planning grounds to justify contravening the development standard.
23The consent authority must be satisfied, at subcl (4), that the written request adequately addresses the matters required to be demonstrated and that the proposal is in the public interest because it is consistent with the objectives of the particular standard and the objectives for development within the zone in which the development is proposed to be carried out.
24The proposal is subject to the objectives and controls of Willoughby Development Control Plan 2006 (DCP 2006).
25Subclause C.3.2.1 design principles of DCP 2006, includes the following in relation to overshadowing:
Minimise the degree of overshadowing of adjacent buildings or open space by using measures such as variation to wall setbacks, roof form and building height or incorporating habitable rooms in roof space.
Solar access is to be available to the principal portion of recreational open space of the development for at least 3 hours between 9am and 3pm on June 22.
The forth facing windows of living areas and the principal portion of the primary recreational open space of adjoining buildings should have at least 3 hours of sunlight between 9am and 3pm on June 22. Where existing overshadowing by buildings and fences is greater than this, solar access should not be reduced by more than 20% (measured in square metres).
26Subclause D2.5.1 of DCP 2006 includes the following in relation to density and height:
To encourage housing densities appropriate to the capacity of the site and its locality while minimising the impact of development on significant views from and solar access to adjoining residential properties.
To ensure that the height and scale of new development are not excessive and relate well to the local context.
27Subclause D2.13.3 of DCP 2006 requires that proposed development does not impact on neighbouring dwellings achieving 3 hours direct solar access in mid-winter.
