STATEMENT OF ENVIRONMENTAL EFFECTS Development Application for 1 TAWA STREET

2.0 Site + Context This item cross-references with the DCP Section 2 General Guidelines : Chapter A – Miscellaneous Part 1 Site and Context Analysis. (see part 4.2 below) 2.1 | Site Location The subject site is located in the Inner West Area. It is legally described as Lot 3 in DP 16828, and is commonly known as No.1 Tawa Street, Ashfield 2131. The site sits at the corner of Tawa Street, the northern facades do not border with any other dwelling.

2.2 | Site description The subject site has a total area of 373m2. The site has a boundary of 14.58m along its primary frontage (northeast boundary) to Tawa Street, 25.15m to the northwest boundary, 13.32m to the southwest boundary, and 28.66m to the southeast boundary. The site slightly slopes to the north corner with a fall of approximately 0.62m. The site is surrounded by “Syzygium Cascade”, street trees. Bungalow is the most prevalent style of housing present in the neighbourhood, including the subject dwelling.

2.3 | Opportunities and constraints In terms of opportunities, situating at the street corner, the northwest and northeast façade receives day-long and abundant sunlight during winter, it provides excellent condition for natural thermal performance during winter. Living areas are exposed to sunlight for more than 3 hours during winter solstice.

In terms of constraints, the northwest side of the site is prone to wild westerly wind, the temperature control on the northwestern side is subject to the climate, and therefore it requires double glazed windows or extra shields of shutters to prevent convection loss.

General Objectives:

-

(a) to improve the quality and amenity of the streetscape, and does not adversely affect adjacent residential areas,

-

(b) to ensure that development has proper regard to environmental constraints and minimises any adverse impacts on biodiversity, water resources, riparian land and natural landforms,

-

(c) to require that new development incorporates the principles of ecologically sustainable development.

4.1.2

Land Zoning Objectives:

-

to provide for the housing needs of the community within a low-density residential environment,

x

Response

The occupant of this property is a family of 4 and requires a large space for activity and living. Internal and external configurations fit occupant’s requirements: single dwelling – subdivision is not necessary.

BRIAN YUNG 490031933 | CHRISTOPHER LEE 490239791

7

STATEMENT OF ENVIRONMENTAL EFFECTS Development Application for 1 TAWA STREET

While subdivision is not required, it is reasonable to provide a full lot area for 4 dependent occupants to maintain a low-density living environment.

4.1.3

Floor Space Ratio Objectives:

-

(a) to establish standards for development density and intensity of land use, refer to DA-A01 – Location Plan,

-

(b) to provide consistency in the bulk and scale of new development with existing development, refer to DA-A01 – Location Plan,

-

(c) to protect the use or enjoyment of adjoining properties and the public domain, creating less close-to-side/rear development is part of the design concerns.

x

Response

The proposed FSR (0.32:1) does not exceed the permissible limit (0.7:1), which is desirable with regards to maintaining consistent bulk and scale with the surroundings. It significantly reduces the chance of overshadowing the neighbour properties and generates a breathable living environment in the property.

4.1.4

Building Height Objectives:

-

(a) to maintain satisfactory sky exposure and daylight to the development landscape, neighbours, and prevent negative visual impact and overshadowing, the development does not exceed the existing building height, all inhabitable space remains on the ground level,

-

(b) to maintain satisfactory solar access to existing buildings and public areas, through the same method mentioned in (a).

x

Response

The proposed building height remains unchanged, to preserve its low-lying and low-profile qualities that are present among the dwellings within the locality. It also prevents overshadowing, obstruction of view and solar access, and intrusion of privacy for its neighbours.

4.1.5

Lot Size Objectives:

-

(a)

-

(b) to set out rules for the calculation of the site area of development for the purpose of applying permitted floor space ratios, including rules to:

to define floor space ratio,

(i) prevent the inclusion in the site area of an area that has no significant development being carried out on it, and

(ii) prevent the inclusion in the site area of an area that has already been included as part of a site area to maximise floor space area in another building, and

(iii) require community land and public places to be dealt with separately.

Proposal A) Miscellaneous

PC1 (DS1.1) Site and Context -

PC1 (DS1.1) Site and Context -

Topography: 1 Tawa Street sits on a slope: level difference less than one metre, more than 600 mm.

Topography: The level difference is an advantage for the courtyard to avoid overshadowing.

Site context: Vegetation - Syzygium ‘Cascade’ Low maintenance, playground friendly, pollution tolerant, light shade all season, flower during summer.

Climate - Temperature up high to 45 celsius degree in summer 2020.

Prevailing wind from the southeast during summer and west during winter.

Site context: Syzygium “Cascade” provides excellent condition for communal interaction, needs an openable intermediate space in response.

Better vegetate with the same street plants as an introduction from street to house. Extra cautions to thermal control: Sawtooth roof to avoid heat during summer and longer sunlight reception during winter.

Detail: Existing setbacks and lot boundary within regulation. Excellent solar access but cautious while planning.

Pattern: Existing - lack of intermediate space, front yard is prerequisite in the neighbourhood. Garden must be preserved. Mostly single and double dwellings in Federation Bungalow style. The neighbourhood has similar code in materiality: terracotta and deep red shingles.

PC1 (DS1.1) Context: Bungalow house in brick. Syzygium Cascade planted along the street.

Most neighbouring houses are single-storey dwellings, except a few double-storey dwellings. Earlyday residential area with colonial heritage.

Detail: Setback regulation to be followed, 900mm for inhabited zones, 450mm for garage and storage.

Light and translucent zone for sunlight to permeate through to the courtyard to avoid overshadowing.

Pattern: The proposed material will be Corrugated metal sheet in red paint for the sawtooth roof cladding with timber studs, to maintain a harmonious and subtle appearance, to be observed from the street.

PC1 (DS1.1) Context: Preserves the front façade and remains bungalow, with low-profile extension of the house finished with contemporary materials to highlight its futuristic and yet local character.

F) Development Category Guidelines PC1 (DS1.1) Context: Typical Bungalow dwelling house in brick. Great landscape proportion in the existing development. *Refer to DA-A03.

PC1 (DS1.3) Context: The existing extended shelter near the backyard is present day architecture but it fails to sympathize with the original bungalow dwellings.

PC3 (DS3.2) Scale: The existing site coverage is 36.4% which is lower than the control standard (60%). The proportion of inhabitable area remains consistent with the adjoining lots.

PC3 (DS3.3) Scale: Maximum building height: I – 8.5m Existing building height: 5.5m It complies with the Ashfield LEP 2013 PC3 (DS3.4) Scale: Maximum external wall height: 6m Existing external wall height: 2.5m It complies with the Ashfield LEP 2013

PC1 (DS1.1) Context: Preserved the existing Bungalow house, to maintain coherence of streetscape. The new proportion remains consistent with the other dwellings. *Refer to DA-A01.

PC1 (DS1.3) Context: The selection of material is contemporary (timber, polycarbonate and colourbond panels), it different from the existing material palette but its sleek, low profile and innovative visual qualities provides the positive provision of the old and new transition. *Refer to DA-P01.

PC3 (DS3.2) Scale: The proposed site coverage is 46.2% which is lower than the control standard (60%). The proportion of inhabitable area is compatible with the adjoining lots.

PC3 (DS3.3) Scale: Building height remains unchanged, thus it complies with the Ashfield LEP 2013 PC3 (DS3.4) Scale: External wall height remains unchanged, thus it complies with the Ashfield LEP 2013

STATEMENT OF ENVIRONMENTAL EFFECTS Development Application for 1 TAWA STREET

5.0 Conclusion This Statement of Environmental Effects has demonstrated that the proposed alterations and additions development at No. 1 Tawa Street, Ashfield is permissible on the site and represents a desirable outcome for the site and the locality.

The proposed development is permissible in the R2 - Low Density Residential zone. It is within the suggested scale of development that is generally practical in this zoning and complies with the height limit and FSR development standards as suggested by Ashfield LEP 2013. In this regard, the proposal will not create a significant adverse amenity impact to the adjoining neighbours and general streetscape. It is designed to avoid any visual impact resulted from huge scale, and consequently the loss of privacy, and overshadowing.

The proposal is to a large extent in compliance with Inner West DCP 2016, the design strategies have carefully considered the key amenity criteria suggested by the DCP. For instance, solar access, private open space, built form, ecology, and setbacks.

The proposal complies with all relevant landscape controls and preserves a significant tree within the site which ensures that the property is provided within a landscape setting which is consistent with the desired future character of the area. Additional landscape plantings on the extended roof will contribute to the scenic quality within the locality and create a refreshing visual and positive environmental impact that will improve liveability in the property for the occupants. The green roof will have no significant impact onto the streetscape, given the green roof sits within the inner part of the property, mostly wrapped by the dwelling house and the garage, except a small part of vegetation is presented to the street public.

Overall, it is convincing that the proposed development represents a decent design outcome which achieves a high level of internal amenity while controlling amenity impact to neighbour dwellings. In this regard, the proposal is an optimal scheme for the occupants on Tawa Street.

Based on these considerations, the proposal is considered to be appropriate for the site and worthy of approval.
