Figure 1. Pennant Street Target Site

1.2. AIMS AND OBJECTIVES OF THIS SECTION OF THE DCP

The objectives of this Section of the DCP are:

To provide a clear vision and desired future character for the Pennant Street Target Site;

To encourage innovative and high quality architectural outcomes that add to the character of the site with particular emphasis

on landmark features, landscape areas, semi – public and private spaces and pedestrian amenity;

To provide detailed design guidance for the creation of an iconic, high quality public domain;

To encourage all developments to address the public street frontage and provide an attractive, safe pedestrian environment;

To ensure development will not detrimentally affect the environment of any adjoining land and that satisfactory measures are incorporated to ameliorate any impacts arising from proposals; and

To encourage appropriate landscaping of developments that contributes to the appearance and amenity of the development site and adjoining public domain areas.

1.3. RELATIONSHIP WITH OTHER PLANS AND POLICIES

In addition to the policies, guidelines and documents specified in Part A – Introduction to The Hills DCP, this Section is to be read in conjunction with other relevant Sections of the DCP, including:

 Part B Section 5 – Residential Flat Building

 Part C Section 1 - Parking

 Part C Section 2 - Signage

 Part C Section 3 – Landscaping

 Part C Section 6 – Flood Controlled Land

Where any provision of this Section of the DCP is inconsistent with any provision of any other Section of the DCP, the provisions of this Section of the DCP shall prevail to the extent of that inconsistency.

This Section should also be considered in relation to DCPs and plans applying to the upgrade of Old Northern Road, the draft Castle Hill Public Domain Plan, The Hills DCP Part D Section 11 - Terminus Street Precinct and The Hills DCP Part D Section 15 – Crane Road Precinct.

2. URBAN CONTEXT

2.1. CASTLE HILL MAJOR CENTRE

The Pennant Street Target Site is situated within the Castle Hill Major Centre (the Centre). The Department of Planning has identified Castle Hill as a Major Centre in the draft North West Subregional Strategy (December 2007). Castle Hill is the premier centre within The Hills Shire Local Government Area

(6)

The Hills Shire Council Page 2 and warrants a high quality urban development, an

efficient local road network and the provision of quality civic infrastructure.

Castle Hill consists of retail, commercial, residential and community uses. Over the past two decades the Centre has experienced rapid growth in the quantity of retail floor space, predominately as a result of the expansion of the existing Castle Towers Shopping Centre.

Continued growth of the Centre is anticipated in the future, including an expected growth in traffic volumes and a growth in demand for retail, commercial and residential floorspace. Developments anticipated in the Centre include the Castle Towers Stage 3 expansion, bus interchange, the planned bus transitway link, the Castle Hill Mainstreet Project civic improvements, the draft Castle Hill Centre Public Domain, the completion of the Castle Hill Ring Road, the planned widening of Showground Road and the development of the Terminus Street and Crane Road Precincts. Within this context the intensification of development on the Pennant Street Target Site is proposed.

2.2. PENNANT STREET TARGET SITE

The Pennant Street Target Site lies immediately to the north of the Castle Hill Major Centre. As such, any future use and development of the Site is influenced, to a degree, by the activities and development that take place within the Centre and the overall role, function and structure of the Centre.

Analysis of the Pennant Street Site’s context can be distilled into the following elements:

 Landform;

 Development and Uses;

 Traffic and Access; and

 Urban Structure.

Landform

The Centre straddles a prominent ridge. The Pennant Street site overlooks the western side of the ridge. The presence of the ridge generates the following opportunities and constraints:

 Views out of the site to the Centre enhance future resident amenity;

 Views into the site provide opportunities to enhance Centre character;

 Opportunities to explore a range of building heights that are not out of keeping with a densely developed commercial centre located on top of the ridge; and

 The presence of a high retaining wall along the southern boundary which provides elevated exposure reinforcing opportunities to enhance the character of the Centre.

Development and Uses

The Centre exhibits a strict separation of land uses with predominantly low density, low scale residential development to the north of the site and high density, high scale commercial development to the south of the site. There is negligible mixed use development within the Centre. Furthermore the Centre is predicted to experience significant development pressure and demand for additional commercial, retail and residential floor space in the medium to long term as the Shire continues to grow and public transport and access improve.

The pattern and scale of uses and development generate the following opportunities and constraints:

 Opportunities to provide a range of dwelling types for residents who may seek and enjoy close proximity, and convenient access, to a Centre at higher densities;

 The need for sensitivity to ensure that the low density residential character to the north of the site is protected; and

 The need to accommodate the impacts of intense commercial development that exists to the south and possibly to the west in the future.

Vehicle Traffic and Pedestrian Access

The Major Centre enjoys vehicular, and pedestrian / bicycle access networks that are destined for significant improvements in the short to medium term. These improvements include the pending completion of the ring road and bus interchange, as well as the development of a rapid bus transitway along Showground Road. The vehicle and pedestrian network generates the following opportunities and constraints:

 The need for good pedestrian access out of the Site to the Centre; and

 The presence of the Ring Road along the southern boundary of the site precludes major vehicle egress from, and access to, the Site;

and

 The impacts of the Ring Road by way of dust, noise, vibration and local pollution need to be accommodated.

(7)

Urban Structure

The structure of the Centre is dominated by the retail presence of the Castle Towers Shopping Centre, the important role of Old Northern Road as the traditional

“main street” and pedestrian access focused on the road.

Council’s Mainstreet Project reinforces its role as the locality’s principal public space. This generates the following opportunities and constraints:

 The recognition that future development and use of the site will act as a buffer, and will be the interface, between two very different components of the Centre structure (i.e. intense commercial and residential), and this presents opportunities for higher or a graduation in residential densities; and

 The need to provide good access to the Centre’s facilities and activities from the site.

3. DEVELOPMENT CONTROLS

The objectives and development controls for development of the Pennant Street Target Site are set out in this Section of the DCP.

3.1. DESIRED FUTURE CHARACTER

The development controls will facilitate a unique development that seeks to balance quality, higher density residential living with the leafy, green suburban character of the Shire. In doing this, the development will seek to:

(i) Establish a strong green character to offset higher residential densities. The development will provide ample provision of a variety of quality open spaces to soften the impacts of the substantial built forms. This will include internal ground level courtyards, shared terrace spaces and roof gardens, vertical landscaping features, a large semi-public central open space and enhancements to the surrounding streetscapes. These will be supplemented by large, outdoor living areas for residents which will overlook these spaces and provide unrivalled internal amenity for residents.

(ii) Be well-connected and integrated with the surrounding areas. The subject site marks a transition between the Castle Hill Centre to the south, and the low-rise residential area to the north.

The development will seek to connect these areas primarily through a semi-public, through-site link that will facilitate movement between these areas.

Development will address the surrounding public spaces and streetscapes, enhancing their safety and vitality.

(iii) Mitigate adverse off-site impacts to surrounding residential properties. As the development will represent a significant shift from the existing character of the surrounding neighbourhood, it must respond as best as possible to limit any adverse off site impacts to these properties, allowing them to continue to experience a reasonable level of amenity.

(iv) Building setbacks will be consistent with the surrounding streetscape qualities and provide space for high quality landscaping.

Higher building forms will be set away from the street to minimise the impacts of overlooking and overshadowing. Detailed design of the development will create heavily modulated building facades which incorporate a variety of harmonious architectural features, colours and textures to minimise visual bulk.

(v) Support the functioning of the Castle Hill Centre and create a high quality, landmark building. In addition to helping to diversify the centre, the development will deliver substantial residential floorspace in the area and contribute to increased housing diversity in the Shire. The design of the development will comprise a unique, quality architectural character and will be an exemplar of green design. In doing so, it will become a landmark building in the area and will raise the design standard not only in the Centre, but in the entire Shire.

(vi) Create a development that represents good design in terms of scale and built form. The built form on the site is to take a podium and tower arrangement. The use of podiums along Gay Street helps provide scale at the pedestrian level to achieve a more comfortable street environment. The tower element is to be setback further from the road frontage, particularly along Gay Street to minimize the bulk and scale of the tower at ground level.

Landscaping is encouraged on podiums to act as a green sanctuary for future residents.

(8)
