Land to which this Section applies

Purpose of this Section

Relationship to other Sections of the DCP

Vision

Development principles

The future population should be provided with access to open space, recreation and community facilities consistent with the lifestyle enjoyed by existing residents. Development which achieves the key principles and meets the development controls in this DCP will provide an exemplary standard of design which makes a positive contribution to the public realm.

Desired Character

Castle Hill North Precinct Structure Plan

Streetscape Areas

"Landscape obstruction streetscape" includes the areas of Gilham Street, Gay Street, Old Castle Hill Road (both sides), Castle Street (west of Carramar Road) and Carramar Road (north of Larool Crescent). The "Terrace Edge Streetscape" includes land along Barrawarn Place, Larool Crescent and Carramar Road (to the south).

Movement network and design

Public Domain

Sunlight to Public Spaces

Integrated Water Management

All landscaping must be compatible with the risk of flooding and must not obstruct overland stormwater flows. On-site retention is to be provided in accordance with Section 4.22 of the Subdivision / Development of Council Planning Guidelines.

Cut and Fill

Each rainwater tank must be provided with potable water drip top-up with a backflow prevention device, meeting Sydney Water requirements.

Ecologically Sustainable Development

Canopy trees, understorey planting and permeable surfaces should be provided where possible to reduce the extent of paved surfaces and to improve the built-up and streetscape. Reduce reliance on mechanical heating and cooling by using overhangs, awnings, good insulation and landscaping.

Residential flat buildings and shop top housing

Site requirements

Building Design

Built form controls

The entrance to the building must be visually identifiable from the street front with clear sight lines. Services such as fire protection, water and electricity distribution must not encroach on the pedestrian's right of way, visually impair the appearance of the building and must be shielded from the street facade with materials that are integrated with the architectural expression. development.

Building height and form

Floor to floor heights and floor to ceiling heights

Primary facade setback  For all buildings, on a street reserve greater than 20m in width (Old Castle Hill Road and Castle Street), all floors above the 6th floor must be set back 3m behind the front building line. Secondary facade setback  For all buildings on a street reserve greater than 20m in width, all floors above the 8th floor must be set back 9m behind the front building line.

Streetscape and the Public Domain Interface

Residential Uses on Ground and First Floors

Podium Design

Tower Form and Design

Roof design and roof features (tower caps)

Roof features will be designed to generate an interesting skyline and enhance views from adjacent developments and surrounding areas. Elevator spillways and all other service equipment must be incorporated into the roof design and hidden from general view.

Adaptable housing

Open space and landscaping

Native ground covers and grasses should be used in garden beds and path surrounds (terrain should be limited to usable outdoor areas). Common open spaces at ground level should be centrally located with high quality landscape treatments.

Safety and Security

Outdoor (outdoor) common open spaces must be capable of accommodating substantial vegetation and must be designed to include facilities for active and passive recreation (such as seating, sunshades, barbecues and children's play areas). Preference should be given to drought tolerant plant species and species that improve habitat and ecology.

Noise

Plant species appropriate to the context and specific microclimate within the development should be selected to maximize the use of endemic and native species and opportunities for urban biodiversity.

Wind

Vehicular and Pedestrian Access

As part of the development, a pedestrian link should be provided through the area to increase the connectivity of the area for local pedestrians. Solid fences will not be allowed at the border of the path, as they will limit passive control over the path.

Terrace housing (attached housing)

The entrance to the facility must be accessible and visible from the street. For strata development, a minimum of 10 m3 of storage space in a lockable garage or basement must be provided for each apartment.

Car parking

The covenant must be registered with the strata plan advising of any shared car parking space. Where basement parking is provided, access to the parking must be via a single front driveway.

Bicycle parking

Approach to Housing Diversity

Development Control will provide guidelines to make neighborhoods livable, including vibrant hubs of activity, permeable and safe movement networks, generous public spaces, high-quality built form and ecologically sustainable development. Quality built form plays a key role in achieving livable, productive and resilient environments and creating great places where people want to live, work, visit and invest.

Activated pedestrian and cycleway

Placemaking will be a key focus to provide neighborhoods that are sustainable, accessible, safe, attractive and well serviced with a unique character and sense of place. A design excellence clause is included in The Hills Local Environment Plan 2012 to require certain buildings and/or development sites to be assessed by a design excellence panel to achieve quality built form outcomes for the areas.

Retail at ground level

Public areas such as informal gathering areas in centers will incorporate high quality and durable elements such as seating, shades and lighting to enhance the amenity of these areas. Streets will be widened where possible by incorporating new public domain treatments including new pavements, new street furniture and lighting, improved pedestrian access and dedicated street tree planting.

Desired future character

Castle Hill North Precinct Structure Plan

Streetscape Area Map

The 'Urban Active Edge Streetscape' includes land along Pennant Street/ Castle Street and the eastern side of Old Castle Hill Road (from McMullen Avenue to just north of Garthowen Crescent). This streetscape will provide a high degree of pedestrian connectivity to Castle Hill Railway Station and other retail and commercial services within the Castle Hill Centre.

Activate Street frontage, Sydney

Making improvements to the public domain, including high-quality paving, street furniture and street trees along these facades, will contribute to the consistency of the streetscape. For land designated as R1 General Residential, retail and commercial use is planned on the ground and first floors.

Ground floor retail, Sydney

This area will have a vibrant and lively streetscape, which will be achieved through a combination of uses and street level activation. For the R4 high-density residential of the land area, neighborhood shops on the first floor are encouraged to meet the daily needs of residents.

Active street frontage, Sydney

Active Street frontage, Sydney

Provide ground and first floor retail and commercial uses with fine grain articulation. The treatment of the front setback areas should be integrated with the public domain treatments identified within the Castle Hill North Public Domain Plan and provide a consistent streetscape.

Residential Development with fine grain residential street interface, Harold Park

Activated street frontage with residential above

This streetscape area includes medium to low-rise buildings with generous setbacks that reflect the character of a landscaped garden. Future development will provide a transition of height and density to reflect the proximity of the Castle Hill Railway Station sites.

Cross section of a Landscape Setback Streetscape

Lower scale development with high quality landscape treatments to be provided along interfaces with sensitive uses.

Landscaped setback Rhodes

Landscaped setback Lindfield

Within the frontage, a minimum of two high canopy trees should be placed per 30m of street frontage where the street setback exceeds 3m. Development is to ensure that the private open space of adjacent properties, including the common open areas of private developments, gets at least 4 hours of sunlight between 9 a.m. and 3 p.m. on June 21.

Cross section of a Landscape Setback Streetscape

Higher density residential development will occur in R4 high density residential zones to provide a range of housing types in the vicinity of the railway station. The northern end of Garthowen Crescent will have an open landscape feel, which will be facilitated through generous landscape setbacks, where a higher density development is proposed, including a mix of native and exotic species (ground cover ( grass), shrubs and trees.

Example Residential Development with open street feel, Wentworth Point

This street will be characterized by a high density of residential buildings in an open landscaped environment. The southern end of the Garthowen Crescent will also have an open plan feel, but this will be a transitional area to the 'Urban Active Edge Streetscape'.

Cross section of Open Street Feel Streetscape

This streetscape will be characterized by terraced streets with soft landscape treatments within the recessed front terraces. Private open spaces in the form of courtyards and small gardens are laid out in the front opposing areas.

Terrace Development

Provide moderate and low planning in the private open courtyards to soften the interface between the built form and the public realm.

Indicative Street Network and Hierarchy

Existing and Proposed Cycleway Network

Driveways that create a 'front-to-back' layout (front-addressed main residences on one side and rear-access garages on the other) should be avoided. Of the 37,934 additional dwellings projected within The Hills Shire from 2016, they will need to accommodate approximately one family household.

Profile – Enhanced Collector Road 1 (Old Castle Hill Road)

Profile – Enhanced Collector Road 2 (Castle Street)

Basement car parking will be consolidated under the building footprint to maximize opportunities for deep soil planting on site. It is therefore reasonable to assume that approximately 62% of the additional housing stock to be provided within The Hills Shire by 2031 will need to be able to accommodate these families.

Profile – Collector Road (Gilham Street and Carramarr Road)

Profile – Local Road 1 (Larool Crescent, Barrawarn Place and Gay Street)

Terraced houses must be a minimum of 2 storeys and a maximum of 3 storeys including attic space. Development applications must demonstrate how the shared car park(s) will be accessed, including where access is through a security gate.

Old Castle Hill Road – Road Widening Plan

All vegetation and structures, including pathways, walls and fences, must be capable of withstanding temporary flooding in all areas designated as retention basins. WSUD must be adopted throughout development, which includes managing water quality and reducing runoff to acceptable levels after development.

Green Wall at 1 Bligh Street, Sydney

Green roofs can help reduce heat absorption, lower the ambient temperature of buildings and improve air quality and building efficiency. Whenever possible, building facades should incorporate vertical landscape features to soften the visual mass of buildings and enhance the appeal of the streetscape.

Greened Balconies to residential apartments

Greenroof in cityscape

Green roofs on higher density development

The proposed development must not exceed the maximum height in floors shown on the structure plan, cf. Figure 6. A horizontal architectural hierarchy must clearly define the ground floor street zone, upper podium and tower elements.

Street façade articulation

Car parking areas at lower levels must be covered by other uses with a minimum depth of 10m to enable the road. Underground car parking must not encroach on the setback zone of 5m from the street boundary or be in line with the building line.

Two storey terrace appearance to street level portion of podium

Balconies up to the upper floors must provide at least 50% opaque/solid railings to provide living comfort.

Example High density residential including site cover outcomes

For all buildings on a street reservation with a width of less than 20 meters, all floors above the 4th floor are 6 meters behind the front facade line. Rear Setback  8m or to meet SEPP 65, whichever is greater. Side Setback  6m or to meet SEPP 65, whichever is greater.

Variety of tower caps

Terraces and patios within 1 m of the natural ground level are included in the calculation of the constructed open space. Where roof gardens and green walls are installed, the Urban Green Cover in NSW - Technical Guidelines, published by the Office of Environment and Heritage, should be considered.

New Acton Roof Top

At street level, the entrance should be articulated with canopies, porticoes, pits or projecting dens for clear identification. Collection of waste should be undertaken from the rear street, or according to the flat of the residential building if the development of the strata is subject to the discussion in the council.

Terrace style housing, Kingston

To improve facilities and mitigate the impact of buildings through the provision of landscaping, including retention and/or planting of trees in deep soil zones. A high level of amenity for residents is achieved through the provision of adequate solar access, natural ventilation, privacy and open spaces.

Terrace style townhouses, Botany

Modern Terrace design, Alexandria

Terraces, Pyrmont

The placement of the apartments must ensure good solar access to the private open space and must not adversely affect the solar access of the neighboring POS apartments. Collapsible or permanent clothes drying equipment should be provided within private open spaces and positioned to maximize the amount of direct sunlight received.

Rear Laneway Principles

The design of the rear lane should take into account the layouts of the following parts. Entrance drawings should end with a landscape treatment or road continuation. Terraces will be designed to facilitate passive surveillance along the rear lane through the positioning of windows and balconies facing the street.

Sample Lane Sections

The housing diversity provision applied within the Sydney Metro Northwest Corridor has been designed to ensure that the future housing stock is suitable to meet the needs of the future population. In view of the above analysis, the incentive provision applied within the Corridor requires that a minimum of 20% of the future apartment stock comprises 3 or more bedrooms.
