2.0 Site and Context Descriptions 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 site is a corner bungalow unit located on 1 Tawa Street, Ashfield, 2131 NSW or known as Lot 3 in DP16828. Tawa Street is found running perpendicular to Church Street and it is in close proximity to Hammond Park as well as the St John’s Anglican Church of Ashfield that is located 350 meters due Southeast from the site and located another 650 meters away is the St John’s Preschool which is also due Southeast from the site.

The site is in a calm quiet residential neighborhood (Low Density Residential Housing, Zone R2) and is not within a heritage site. The surrounding developments around the sites are single storey buildings with them organized in an orthogonal grid layout, along vehicular streets.

2.2 Site Description Item

Description

Address Legal Description Overall Area Length of Boundaries

1 Tawa Street, Ashfield, NSW, 2131 Lot 3, DP16828 372.2 m2 NW Boundary – 25.2 m SW Boundary – 13.3 m SE Boundary – 28.7 m NE Boundary – 10.2 m

Surrounding Context

The site is located in a quiet residential area in the suburb of Ashfield, approximately 9.5 kilometers from Sydney CBD. Found on the Tawa street that is located perpendicular to Church street. The neighborhood lots are orientated in an orthogonal grid layout with garages facing an vehicular streets to allow easy parking for the residential housing. The dwelling is located in a low density residential housing R2 zone, with a dense foliage landscape with improves the overall environment and privacy of the neighborhood. As well as tall apartment blocks found on the Southestern boundary of the site which may result in the intrusion of the privacy of the courtyard spaces as it overlooks the site.

Significant Landscaping

There are tall trees located in the Northwestern boundary of the site which may cause some overshadowing of the courtyard of the site during the winter months.

Character of Houses

The houses located on the site reflect the rich historical context of the land it sits on, which is done through its beautiful red brick Victorian façade design and its red brick veneer house frontage designs along with its red terracota roof tiles.

Site Description

The dwelling is currently a single storey residential housing with a Victorian design house frontage, with a detached garage at the rear end of the site. The site is a corner lot bungalow with a garden with a pavement connecting the dwelling to the garage.

Topography

The site has a gentle and even gradient. With a slight slope between the Southeastern and Northwestern boundary allowing stormwater from the roofs of the building to flow towards the stormwater drains located on the streets of the Northwest boundary.

2.3 Opportunities and Constraints There are many hidden opportunities as well as constraints that had influenced the proposed design for the site, with great consideration we have collaboratively worked with the client’s needs to fulfill with their requests and worked around the challenges that are found on the site.

Opportunities Orientation – The building that sits on the site is orientated to face the Northeast direction and this allows it to be able to fully take advantage of the Western morning sun, especially during the winter months, to improve the existing amount of natural light illuminating the interiors of the building.

Courtyard – The existing dwelling has a large spacious courtyard that is currently utilized, with its current layout, the courtyard acts like a threshold separating the functions of the main dwelling and the garage. An opportunity is to open the rear part of the existing building by having a spacious open courtyard living concept and to use a timber decking to seamlessly connect the outdoor and indoor spaces together. Allowing the activities from the main dwelling to bleed into the outdoor courtyard spaces, blurring and challenging the idea of boundaries/ thresholds.

Roof – The building as an existing roof line of 5.5 meters however the plastered ceiling has only allowed the interior heights of approximately 3 meters, leaving the remainder height of 2.5 meters not utilized. There is an opportunity to open up the plaster ceiling and exposing the beautiful timber frames of the gable roof structure and creating a spacious atmosphere, the double ceiling height can also accommodate a small loft space for the children’s private lounge space as well.

Constraints House Frontage – To conform with the heritage character of the streetscape can be one of the constraints of the site despite the fact that it isn’t a heritage conservation zone. But the decision was made to preserve the existing frontage of the Victorian red brick design in order to have a harmonious streetscape. The relationship can be observed in Figure 5.

Façade – No changes would be made to the existing façade of the building especially the frontage of the house in order to keep a harmonious streetscape as well as the fencings of the Northwest and Southeast boundaries.

Overshadowing – In order to have a good relationship with the adjacent houses the decision to keep the building as a single storey dwelling has been proposed in the design, with that consideration in mind however, the roof line of the rear part of the building will be demolished to have a new roof line of 6 meters tall instead of 5.5 meters. This proposal will have minimal impact to the neighbors.

STATEMENT OF ENVIRONMENTAL EFFECTS Development Application for 1 Tawa Street, Ashfield

Privacy – Due to locality of the site being on an intersection, it is expected that there will issues with the intrusion of privacy from the street especially when with it being a corner lot. Thus, this restricts the window size and number of façade openings towards the Northwestern boundary of the site.

2.4 Neighboring Development and Compatibility with Adjoining Development The site is part of a larger community of 12 developments found along Tawa Street (with the house number that goes as follows of 1, 2, 2A, 3, 3A, 4, 4A, 5, 6, 8, 23, 25). With all the houses arranged in an orthogonal manner along the vehicular street. The site shares the most similarities with the arrangements of amenities with No. 23, as they both feature a detached garage that faces the street allowing easy parking access. Whereas the other houses utilizes a driveway leading into their lots. The houses found on neighboring development of the site are single storey building with the exceptions of house No. 5 that is a double storey building.

The developments can be observed to have made attempts to preserve the Victorian red brick house frontage, as seen with the houses with the houses that had the most recent renovations to be house No. 2A with its brick frontage being painted over by a coat of white paint.

STATEMENT OF ENVIRONMENTAL EFFECTS Development Application for 1 Tawa Street, Ashfield

5.0 Conclusion The Statement of Environmental Effects (SEE) was prepared on behalf of Calvin Tan and Nimit Batavia, for it to be submitted to the Inner West Council attached with the Development Application and BASIX Report to address the alteration and additions which will be carried out to the existing development on 1 Tawa Street (Lot 3, DP16828). The alteration and additions that are addressed in the proposal includes an alteration and remodeling of the rear part of the existing building along with a new ridgeline of the roof RL22.40 m.

The contents of the SEE describe the proposed development of the site in detail with heavy considerations of the not only the sites context, the clients’ requirements but also to have the need to comply with Ashfield Local Environmental Plan 2013 and the Developmental Control Plan 2016 as well. With this said, some of the issues that are prevalent in the existing development the proposal will be providing a solution for are: Privacy – By introducing a laneway on the Southeast boundary allow it to provide visual privacy to the courtyard spaces from the tall apartments located in that general direction to protect the clients’ privacy as the courtyard becomes a new recreational space.

Overshadowing – The proposed development will not increase any overshadowing to the adjacent neighboring buildings especially during the winter months, allowing to have a good relationship and to gain the approval of the neighbors for the renovation works.

Solar Access – More windows and openings with glazing doors facing towards the Southwest direction of the boundary to allow for more passive solar access/ illumination of interior living spaces, with proper shading solutions provided such as glazed windows or adjustable shading elements as well.

Ventilation – An open concept design with a centralized courtyard design, this allows all the openings to open up to the courtyard which functions as an air well and creating this microenvironment providing the much-needed ventilation to interior spaces.

We appreciate that you have taken your time to go through this proposal in detail, if there are any documentations missing or in need of further clarification, please do not hesitate to contact us.

Hence, we hope that this well considered design proposal worthy and able to gain the council’s approval.

Sincerely, Calvin Tan & Nimit Batavia TANAVIA Architects

The concept of central courtyard was key to our design concept. The courtyard doesn’t only guide cirulation but also serves as the pivotal space that all spaces opeb into and hence serves as a place of social activity and gathering.

The deck serves as a transition space between the exterior courtyard and interior rooms - it can serve as a great place to dine and also study/relax.

The residential scheme is divided into two distinct parts - the front of house which houses the kids bedrooms and the back of house that houses the parents bedroom - the laneway connects these two spaces and wraps around the deck and courtyard.

The rooftop garden is an inaccessible space but provides key vegetaion that hangs over the deck space, improving ventilation and making the home more sustainable.

Introduction of the glass panels on the laneway in the building concept design helps to increase the amount of natural light the courtyard receives by utilising the material’s reflectivity to partially reflect sunlight into the courtyard space. This is specially crucial during the winter months where the angle of the sun is low.

MATERIAL PALETE + SUSTAINABILITY

Polished concrete finishings for the floors for the laneway and garage dwellings, as they are great to act as thermal masses to provide passive cooling and heating in the interiors of the building.

WPC decking board painted with a layer of oil coating to protect the timber. The deck will act as an element which connects the building with the courtyard, providing a seamless transition into indoor and outdoor spaces further pushing the centralised courtyard concept.

Green roof for the laneway building, which not only provides more greenery to these spaces of the laneway; reduces stormwater surface run off preventing floodings.

Glazed glass panels to be used for the folding glass doors, the double glazing helps to retain heat keeping the interiors at a comfortable temperature saving costs, as well as partially reflecting light to the courtyard where it is dimly lit most of the time of the year due to overshadowing from neighbouring trees.

Stainless steel glass folding doors to aid in allow easy access into the courtyard space and the outdoor facilities, doors also provides for easy ventilation that allows constant fresh air in the interiors of the building.

As studies have should that fresh air allows for many health benefits such as improved sleep quality, increased productivity and concentration. Furthermore thee courtyard passively acts as an airwell.

STORM DRAIN

Areas with plenty of vegetation and green roofs, helps to reduce surface run off from occuring reducing the probably of flooding in the area.
