DESIGN DEVELOPMENTThe Design Development phase has built upon earlier phases by furthering the design resolution of the external spaces and developing strategies to address the challenges of site drainage, ac-cessibility to elevated buildings, aesthetic division of spaces, the creation of comfortable and inter-esting external spaces and the provision of robust, flexible activity spaces for Youth and Children.The design of the external areas has developed in response to the further conceptual develop-ment that has occurred during the Design Development phase as described in section “4.0 Design Response”.

Coloured external surfacesThe coloured building facade is an expression of the design response and the exterior surfaces continue this col-ouration allowing the expression to be drawn through the landscape spaces. This coloured banding of the ground surface provides a sense of increasing warmth to the vibrant sheltered centre.

Drainage and accessibilityDrainage and accessibility have been addressed with a strategy of dividing the site into three different planes that can rise and fall independently of each other. These planes or levels are:• The Building level • The Circulation Level • The Planting and Drainage LevelThis separation allows the circulation level to unify with the existing surrounds of the site and appropriately meet the building level. Potentially multiple building levels could exist to the requirements for flood mitigation, which dictate the elevation of the buildings above their surrounds. A separate circulation level can gradually rise to meet building access points and fall to meet the existing surrounds, effectively allowing opportunity for long gradually sloping pathways rather than steeper ramps. The planting and drainage level can independently manage the drainage flow requirements and be suitably shaped to accommodate flows into suitable surrounding areas. The most significant drainage area is immediately to the north of the built from and will receive run off from the roof structure. A robust planted swale is proposed along this area with stone pitching to provide reinforcement at zones of water fall from the roof. All other gardens beds are proposed to be at lower level than the circulation to receive any runoff that may occur from these hard surfaces, and especially to create a “low flow” passage of water separate from the circulation surface to minimising staining and other potential issues. Garden beds that are anticipated to receive frequent run off can utilise gravel fill trench drains to provide enhanced stability.




Division of spacesA variety of functions, demographics and user groups will coexist within the Community Hub and consideration is required to provide desirable means of full, partial or suggested separation. Appropriate division of spaces has been explored through distinct metallic screening and vegetation buffering. X-tend steel mesh is proposed and a fencing material to secure the ELC centre and the multi-purpose room’s external spaces. The external face of these fences is proposed to be inhabited by climbing plants to create a softening effect and the internal face to be cover in interactive play opportunities. The design aims to make a feature of both sides of the fence that positively contributes to the experience of the space thereby avoiding the negative impacts associated with fencing and reducing the fence’s presence.

ELC external spaceThe ELC centre schematic design has focused on the provision of flexible open space for temporary activities, key attraction areas with some functional programming, and interactive fencing that reduces the comprehension of enclosure. The design aims for flexibility to allow diversity to the experience of children frequently attending the centre. The surfaces are robust with open concrete hardstand, sand pit and play mulch to allow an ease of main-tenance and supervision. The open sand pit is large enough to include a variety of mobile or fixed play equipment as per the desires of the ELC centre. A raised garden bed is included to the perimeter of the ELC space which will initially be planted with robust local plants and can be converted to a vegetable or herb garden. Within the natural play mulch are climbing and stepping elements to challenge children and encourage active play.

Comfortable, interesting spacesSeating opportunities for solitary or social experience is provided along the circulation routes striving for a social street rather than a utilitarian access way experience. These seating opportunities face the main transit paths rather than be isolated from the pathways. This increases the level of social interaction and passive surveillance across the site. Additional interest is created through the inclusion of planting throughout the site, even beneath the roof canopy. The central heart of the site is conceptualised as the “soft underbelly” separated from the harsh Pilbara context by the protective “carapace” of the roof structure. The planting enhances this with soft, lush, colourful, dense planting in the central areas beneath the canopy and locally inspired planting in the surrounding exposed areas to connect the Wickham Community Hub to its broader landscape context. In the areas external to the roof structure a focus on tree planting will prevail. Naturalistic groups of local tree species (eg. Eucalyptus vitrix) will give general defi-nition to the site perimeter along with integration to surrounding landscape and avenue plantings of exotic shade species (eg. Delonix regia) will provide shade to inhabitable spaces such as walkways and seating areas.

SITE ANALYSIS

Pedestrian and cycle pathsA• A hierarchy of constructed paths intersect the site at defined points.• Circling the site is a cycle path that connects to a town’s larger cycling network.

Informal PathsB• The northern portion of the site is traversed by informal paths that have been created by continual pedestrian

movements that have restricted vegetation growth.• These paths demonstrate the current movement patterns in this portion of the site.

Barriers (Level changes, fences, built form)C• Fences, Level changes and built form create barriers to movement dividing the site.

Entry Points / DestinationsD• Access routes from site arrival points to site destinations create a concentration of movement and give a hierar-

chy to the movement network.• Movement concentrations represent connection spaces that require appropriate treatment.

Existing Vegetation and DrainageE• A wide, shallow moderately vegetated (mainly groundcovers) swale runs along the western site boundary and

receives the overland drainage flow from the site.• A mixture of local and exotic species exists on site, the recent exotics to shade carpark areas are in poor

health.

Road NetworkF• Vehicle access to the site is through a single entrance road on the eastern edge of the site.• Adjacent residential areas to the west are not directly connected by road to the site.• Parking is in the centre of the site from which the visitor moves outward to destinations.

Site FunctionG• A central carpark services the surrounding active recreation facilities.• A compartmentalisation exists with each space singular in its intent.

Context InterfaceH• The preferred location interfaces with the existing (southern border) along a 1.2m (approx.) level change,

fenced cricket and tennis facilities and a tall squash facility.• The site’s west is bordered by a drainage swale, the east a carpark and the north an area of low vegetation.
