2.0 Site and Context 2.1 Description of Site The site is located at 64 Morris Street, Summer Hill. It is located on the eastern side of Morris Street. The closest cross street – Junction Road – is located to the south of the site. The site is legally described as lot B of DP 435461. The site is rectangular and has a 6.4m frontage to Morris Street. There is a party wall that runs along much of the northern boundary of the site at 25.90 meters long. The site itself is 253.8m2 with the entrance to the site facing west towards Morris Street. Due to the site being the southern side of a semi-, it receives very little natural light and ventilation throughout the year. The current floor plan also further restricts any direct sunlight access and ventilation.

STATEMENT OF ENVIRONMENTAL EFFECTS – 64 Morris Street, Summer Hill
2.2 Neighbouring Sites 64 Morris Street is located towards the southern end of Morris Street. The Eastern side of Morris Street – on which the property is located – is characterised by lowdensity, residential buildings that follow a similar roof line. The facades of the buildings facing Morris Street are narrow and create a consistent setback from the street. The neighbours on the northern side of the site share a party wall with the dwelling to which the entrances to both dwellings are located towards.
Figure 2: Regular roofline & regular setback on the eastern side of Morris Street. In contrast to this, the western side of Morris Street features a range of different buildings from differing periods with differing styles. Immediately across is a development characterised by two-level, low-rise apartment buildings. Further north, there are three twolevel Victorian terraces with narrow frontages that contrast with the apartment-style development to the south.

STATEMENT OF ENVIRONMENTAL EFFECTS – 64 Morris Street, Summer Hill
3.0 Proposed Development The proposed development ensures that the building maintains its original 19th century-style features visible from Morris Street. The current building lacks light and natural ventilation. The proposed development aims to resolve light, natural ventilations and improve the quality of spaces in the existing dwelling as well as providing an additional bathroom and lounge room. In order to maintain the existing 19th century façade towards Morris Street, there is a proposed addition of another storey towards the rear of the current house. No changes have been proposed for the front of the house. The additional storey will have little impact on the scale and bulk of the building as visible from the street. The maximum height of the building will only increase by 941mm. The current lounge room towards the centre of the house will be demolished to make way for a new courtyard that will introduce light and air into the building to improve natural lighting, ventilation and amenity. The courtyard will also provide the residents with more open private space.
4.0 Planning Control and Assessment This section provides an in-depth explanation of the proposed development in relation the guidelines of Ashfield LEP and Interim DCP. 4.1 Ashfield Local Environmental Plan 2013 4.1.1 Degree of Compliance Table 1: Summary of LEP controls and degree of proposed compliance Clause

The proposed development complies with all controls except for the side setback on the northern side of the site. This is a result of design decisions that prioritise solar access to the property on the southern side rather than compliance with the DCP. The following sections will analyse and discuss this decision further.

STATEMENT OF ENVIRONMENTAL EFFECTS – 64 Morris Street, Summer Hill
4.3 Planning Controls and Assessment Context (Clause 1.0) The proposed development responds to the shape of the existing roof patterns on Morris Street. The new addition respects the existing structure by not imitating it and ensuring that the language and materials differ to ensure residents and guests can differentiate between the existing 19th Century home and its extension. Scale and Bulk (Clause 2.0) The eastern side of Morris Street features a row of homes that share a regular roof line and a regular setback as shown in figure 2. Due to constraints, such as lot size, landscaped area constraints, deep soil constraints as well as considerations about quality of life, direct sunlight and access and ventilation, a decision has been made to demolish and reconstruct the rear of the home which includes an addition of a second storey. The second storey will be slightly visible from street level, however there is a large tree located at the front of the property… The proposed addition complies with both the floor space ratio and building height constraints as defined by the Ashfield Local Environmental Plan 2012. Aesthetics (Clause 3.0) A large part of the aesthetics requirements outlined in the Ashfield Interim DCP focuses on the scale and bulk of any additions in regards to the existing context. The proposed redevelopment and second storey addition has been designed to mimic the predominant roofline of the existing semi as and the houses surrounding the site. The DCP has an emphasis on ‘sympathetic’ development that imitates the existing structure. However, it also states that any extensions that differ in style and materials should be skilfully designed to contrast the existing structure. The proposed material palette and shape of the redevelopment and second storey extension provides a strong contrast to the existing 19th century semi-. There is a clear distinction between the existing structure not only when it comes to materials, but when it comes to floor level (being 280mm lower than the front of the semi- at the current lowest level of the existing rear of the structure). Landscape and Site Layout (Clause 4.0)
Jarrod Haynes | 440173788

The Ashfield Interim DCP states that minimum of 35% percent of the site should be landscaped area. The proposed rear redevelopment and second storey addition maintains the existing open space as well as providing an extra 12.6m2 of open space and deep soil in the form of a courtyard that separates the existing structure from the redevelopment. The addition of a courtyard will increase the landscaped area that is currently below requirements at 34.7% to 37.3%. The Ashfield DCP requires at least 70% of the total minimum landscaped area to be deep soil. The proposal also includes a design for the backyard of 64 Morris Street. This proposal includes demolishing the existing shed at the rear of the lot and adding narrow concrete pavers to allow residents and visitors to easily walk deeper into the backyard. Setbacks (Clause 4.6) The Ashfield Interim DCP 2013 states that side setbacks must be compliant with the BCA’s requirements of 900mm. There is a small, inoperable window located in the 900mm setback used by the laundry (W08). There are no windows located within the 900mm setback and the location of the stair well leading up to the second storey addition ensures that there is no opportunity for overlooking from the balcony. Tree Preservation (Clause 4.8) Ashfield Development Control Plan requires trees taller than 5 meters with trunk girths 350mm and larger at ground level are maintained. The proposed development does not require any removal of trees thus meeting the tree preservation clause. Amenity for Neighbours (Clause 5.0) The proposed development that includes an addition of a second level has been designed to ensure that the neighbour on the southern side has their privacy maintained. There is only one window located on the second storey on the southern side. The window is located in the upstairs bathroom. Not being a habitable room, there is less opportunity for the privacy of the neighbours to be compromised.

STATEMENT OF ENVIRONMENTAL EFFECTS – 64 Morris Street, Summer Hill
5.0 Conclusion The proposed development has been designed to minimise visual impact when viewed from Morris Street. The rear addition is barely visible from the street and will largely be blocked from view by the existing tree at the front of 64 & 62 Morris Street. The demolition and reorganisation of the rear, as well as the addition of the second storey, improves the quality of life of the residents with minimal impact to the streetscape and neighbours.
