The planning framework
10The site is located within the R4 Zone - High Density Residential, pursuant to Lane Cove Local Environment Plan 2009 (LEP 2009). Development for the purposes of a dwelling house is prohibited within the R4 Zone. The site benefits from existing use rights, pursuant s 107(1) of the Environmental Planning and Assessment Act 1979 (EPA Act), for the purposes of a dwelling house.
11An existing use may be rebuilt, pursuant to s 41(1)(c) of the Environmental Planning and Assessment Regulations 2000 (EPA Regulations). Development consent is required for the rebuilding of the dwelling house, pursuant to s 107(2)(a) of the EPA Act.
12Section 108(3) of EPA Act, states:
An environmental planning instrument may, in accordance with this Act, contain provisions extending, expanding or supplementing the incorporated provisions, but any provisions (other than incorporated provisions) in such an instrument that, but for this subsection, would derogate or have the effect of derogating from the incorporated provisions have no force or effect while the incorporated provisions remain in force.
13A draft LEP has been prepared which includes a proposal to rezone the properties to the north of Kullah Parade, between the western end of Kullah Parade and Giraween Avenue, to E4 - Environmental Living. The planning proposal has been approved by the Minister for exhibition under the Gateway process and community consultation has been conducted in accordance with the requirements of the Minister. The planning proposal was referred to the NSW Department of Planning and Infrastructure on 30 April 2012 requesting gazettal.
14Dwelling houses are permitted with consent in the E4 - Environmental Living Zone and the E4 zone adopts the floor space ratio (FSR) and height controls of the R2 - Low Density Residential Zone, which are FSR 0.5:1 and a maximum height of 9.5m. The objectives of the E4 - Environmental Living Zone are as follows:
To provide for low-impact residential development in areas with special ecological, scientific or aesthetic values.
To ensure that residential development does not have an adverse effect on those values.
15The site is identified as bushfire prone, by the Bushfire Prone Land Map (Exhibit 7).
16The aims of LEP 2009 include, at clause 1.2(2):
(c) in relation to residential development, to provide a housing mix and density that:
(i) accords with urban consolidation principles, and
(ii) is compatible with the existing environmental character of the locality, and
(iii) has a sympathetic and harmonious relationship with adjoining development,
17The zone objectives of LEP 2009 include, at clause 2.3(2):
The consent authority must have regard to the objectives for development in a zone when determining a development application in respect of land within the zone.
18The development control for the height of buildings, at clause 4.3 of LEP 2009, states:
(1) The objectives of this clause are as follows:
(a) to minimise any overshadowing, loss of privacy and visual impacts of development on neighbouring properties, particularly where zones meet, and
(b) to maximise sunlight for the public domain, and
(c) to relate development to topography.
(2) The height of a building on any land is not to exceed the maximum height shown for the land on the Height of Buildings Map.
(2A) Despite subclause (2), the maximum height for multi dwelling housing on land in Zone R2 Low Density Residential is 5 metres.
19The development control for FSR, at clause 4.4 of LEP 2009, states:
(1) The objectives of this clause are as follows:
(a) to ensure that the bulk and scale of development is compatible with the character of the locality.
(2) The maximum floor space ratio for a building on any land is not to exceed the floor space ratio shown for the land on the Floor Space Ratio Map.
(2A) Despite subclause (2):
(a) the maximum floor space ratio for multi dwelling housing on land in Area 1 on the Floor Space Ratio Map is 0.4:1, and
(b) the maximum floor space ratio for a building containing shop top housing on land in Area 2 on the Floor Space Ratio Map is 2.5:1.
20The relevant objectives for dwelling houses and dual occupancies, at clause 1.1 of the Lane Cove Development Control Plan 2009 (DCP 2009) are as follows:
- Provide dwellings in landscaped lots.
- Ensure new dwellings and alterations & additions to existing dwellings are well designed and compatible with the surrounding context and enhance the streetscape within the area.
21The relevant objectives of setbacks, at clause 1.3 of DCP 2009 are as follows:
7 Maintain the predominant street setback.
8 To enhance and maintain vegetation corridors through landscaping within front and rear gardens and side boundaries.
9 Side and rear setbacks are to provide building separation, sunlight, landscaping, ventilation, public views (if appropriate) for the dwelling and its neighbours.
22Clause 1.3.2 Side setbacks, of DCP 2009 includes the following:
a) Side setbacks are to be a minimum of:
I. 1.2m for a single storey dwelling
II. 1.5m for a two storey dwelling.
Irregular sites may be considered on their merits.
23The relevant objectives for cut and fill, at clause 1.6 of DCP 2009 are as follows:
1 Retain the natural ground levels as much as possible of a site and its existing landforms particularly in relation to the street or adjacent private open space areas.
2 To achieve reasonable landscaping within development.
3 To minimise the extent of cut and fill and its impact along side boundaries.
4 To create a consistent relationship between the dwelling and the street.
5 To ensure that excavation and filling of a site does not result in unreasonable amenity impacts to adjoining dwellings.
6 To minimise change to water run-off patterns.
24The provisions for cut and fill include, at clause 1.6 of DCP 2009 the following:
d) Development is limited to a maximum depth of excavation or fill of 1m at any point on the site unless it is demonstrated that the site's slope is too steep to reasonably construct a 2 storey dwelling with this extent of excavation.
25The objectives for building design, at clause 1.7, include the following:
1 Ensure new dwellings and alterations and additions to existing dwellings reinforce the typical bulk and scale of existing dwellings within the street and the area.
2 Ensure that alterations and additions to existing dwellings maintain the integrity of the design and style of the existing building.
3 Ensure elevations to the street and public domain are well proportioned and designed.
4 Minimise impact in terms of overshadowing, loss of privacy, light spillage to adjoining properties, loss of views and amenity.
26Clause 1.7.1 Height of DCP 2009 includes the following:
c) The maximum height of a parapet roof is to be 600mm above the maximum wall height of a dwelling.
d) The maximum height for a pitched roof house is 9.5m above ground level (existing).
e) A maximum of 2 storeys plus basement is permissible at any point above ground level (existing). No building will be permitted to have an appearance (in elevation) exceeding three storeys in height.
