Design A new double storey dwelling with detached secondary dwelling at EDENSOR PARK NSW 2176, Fairfield council

The site is a rectangle-shaped land. And it is a vacant lot. The surrounding dwellings comprise single-storey dwellings and double-storey dwellings. Adjacent to the rear is a vacant lot. Adjacent to the eastern boundary is currently a single storey house and adjacent to the western side is a vacant Lot too.

The proposed site has 582.5 m² with the front boundary of 19.66m & rear boundary of 19.66m, eastern side boundary of 29.63m and western side boundary of 29.63m. The Natural ground level near the frontage is (76.10), while it is (75.87-75.49) near the rear side.

The site falls softly from front to rear (south to north) then it falls very softly from side to side west to east, then it slops back to the street through the driveway.

The Land in zone R2, which is Low-Density Residential.

The frontage, on Edensor Park Road, is orientated towards the south (check the survey plan).  

 

4.0       THE PROPOSAL

The proposal is to construct two storeys dwelling with detached secondary dwellings at the rear. The dwelling will include 5 beds & a study room, a living & dining room and a family space upstairs. The secondary dwelling will include 2 beds with bathroom, kitchen, dining and living area.

5.0       RELEVANT PLANNING CONTROLS

5.1       LEP and land-use zoning

The subject site is within the Zone R2 – – Low–density residential. Dwelling houses are permitted subject to development consent within this zone.

The objectives of the zone are:

 

A.    To provide for the housing needs of the community within a low-density residential environment. To provide a variety of housing types within a medium-density residential environment.

B.   To enable other land uses that provides facilities or services to meet the day to day needs of residents.

 

It is considered that the proposed development satisfies all relevant zone objectives contained in the FLEP 2013 as follows:

1     A permissible form of development is being provided on an allotment of land that exceeds the minimum allotment size for dwelling house and secondary dwelling development;

2     Consideration has been given to the existing amenity and character of the area and it is considered that the proposed development is sympathetic and harmonious with adjoining development and will complement the existing character of the locality;

3     The proposed development will enhance the amenity of the residential area by the provision of new affordable residential accommodation and landscaping; and

4     The the development will add to the range of housing in the zone through the provision of an average size family dwelling with extended family facilities.

 

5.1.1    Height of Buildings (Clause 4.3)

The objectives of this clause are as follows:

1     To establish the maximum height for buildings,

2     To ensure that the height of buildings complements the streetscape and character of the area in which the buildings are located,

3     To minimise the visual impact, disruption of views, loss of privacy and loss of solar access to existing development.

The Height of Building Map categorises the site within the maximum 9m building height limit. The proposed dwelling house has a maximum height of 8.69m at the lowest natural ground level which satisfies the requirements of the clause.

5.1.2    Floor Space Ratio (Clause 4.4)

The objectives of this clause are as follows:

(a) To provide an appropriate density of development consistent with the established centres hierarchy,

(b) To ensure building density, bulk and scale make a positive contribution toward the desired built form as identified by the established centres hierarchy.

The FSR Map indicates a maximum FSR of 0.45:1 for the subject site which the proposal complies with, having an FSR of 0.45:1. In terms of bulk and scale, the proposed 2 storeys dwelling and the low scale secondary dwelling will be comparable to other already built dwellings in the locality.

5.1.3    Exceptions to development standards (Clause 4.6)

Consent may, subject to this clause, be granted for development even though the development would contravene a development standard imposed by this or any other environmental planning instrument. In this regard, NO variation requests are required as the proposal complies with all development standards contained in FLEP 2013.

5.1.4    Preservation of trees and vegetation (Clause 5.9)

The proposal does not involve the removal of any trees. New trees will be planted as indicated on the Landscape Plan which will enhance the future amenity of the site and locality.

5.1.5    Heritage Conservation (Clause 5.10)

The subject site is not listed as a heritage item or located near any heritage-listed items.

5.1.6    Bushfire Hazard Reduction (Clause 5.11)

The subject site is not identified as being in a bushfire prone area.

5.1.7    Acid Sulfate Soils (Clause 6.1)

According to the Acid Sulfate Soils Map, the subject site is not within a classification category known for acid sulphate soils to occur.

5.1.8    Flood Planning (Clause 6.3)

The site is not identified as on flood-prone land.  

 

5.2        FAIRFIELD DCP

The Fairfield DCP 2013 covers ‘Dwelling House’ development. The relevant planning principles outlined in the the plan has been incorporated into the design of the proposed development, resulting in an appropriate outcome for the site having minimal impact on adjoining and nearby development.

5.3.1    BASIX

On the 1^st July 2004, the State government introduced BASIX, which consolidates planning provisions relating to water consumption and greenhouse gas emissions. A BASIX Certificate is provided with the application demonstrating the applicant’s commitments in achieving the objectives of the state government’s policy. The BASIX SEPP states in clause 8 and 9 that:

 

“‘competing provisions’ in an environmental planning instrument or Development Control Plan are of no effect about a residential development proposal required to be assessed by BASIX, ‘to the extent to which they aim:

(a) To reduce consumption of mains-supplied potable water, or reduce emissions of greenhouse

Gasses in the use of a building to which this Policy applies or in the use of the land on which

Such a building is situated; or

(b) To improve the thermal performance of the building to which this Policy applies.’”

It is proposed to install a rainwater tank as specified at the BASIX certificate to hold water for the proposed principal dwelling, to be used for flushing toilets, clothes washing and outdoor irrigation, which satisfies the requirements of the policy.

Energy conservation principles will be achieved through the construction method and orientation of the building, together with future thoughtful planting of trees and shrubs.

 

5.3.2    Internal Driveways

A relatively level site ensures that appropriate driveway grades can be achieved following AS 2890.2 - 2002. The Architectural Plans provide a driveway profile to demonstrate compliance.

 

5.3.3    Waste Disposal & Re-use Facilities

A Waste Management Plan will be submitted as a separate document to accompany the demolition application. The plan adopts the principles of Avoid Reuse Recycle and Dispose to minimise landfill waste.

5.3.4    Crime Prevention through Environmental Design

Design guidelines outlined in the Crime Prevention through Environmental Design (CPTED) were considered and incorporated as follows:

·         Provision of a clearly visible entry point facing the street;

·         Passive surveillance treatment has been provided through the provision of habitable rooms and a balcony which face the street;

·         Suitable landscaping will produce a defensible open space at the front, resulting in some interaction with the public domain beyond; and

·         Boundary fencing and gates will be provided to prevent intruders from accessing the private open space area.
