The City of Kalgoorlie- Boulder was established in 1893 during the Western Australian gold rushes and rapidly expanded, continuing with the extraction of gold and hosting one of the largest open- cut gold mines in Australia.
St Barbara Square Kalgoorlie transforms rear laneway service and adjacent space into a new ‘Kalgoorlie Heart’. ‘’Kurturtu is a highly activated public space, that pulses with the energy of the region and community, offering facilities and new experiences for all people. The new design carefully stiches together existing access points while weaving in new city connections. It is supported by three key themes: A hand-built city, (Re)discovery and Catalyse. This is bound by a collection of specific narratives that reveal the unique qualities of Kalgoorlie – Boulder and this site including; What Lies Below, Water, Between Heaven and Earth, Woodlands, Kalkurla (Silky Pear), Woodlines, Architecture, Streetscapes and Tracks, Golden Pipeline, Structures of the Mines.
Conceptually, the square brings to the surface the ancient geological formations. The banding on the ground plane references the greenstone and granite - navigating the visitor through the square. The expression of water negotiates these fault lines and channels, but also speaks of ancient gnammas, springs, and salt lakes. Water becomes a catalyst for play, meeting, and gathering. It is the destination, under the central canopy titled “Hovering Earth”, ‘what lies below’ is peeled away, lifted above, revealed, in awe and delight. A golden seam. Shelter under the earth (by day) and the heavens (by night). St Barbara patron saint presides above metaphorically, and watches on. The seating pods like topographic and geological formations, nestle under the canopy of woodland and offers respite amongst generous planting beds.
The canopy form references the adjacent mine sites and the extraction of earth and the creation of new landscapes.
The sinuous form and inverted contours hover precariously above, activated with sound, misting and lighting, inviting visitors to participate and become part of the spectacle.
The spectacular quality of the canopy (8.0m cantilevers) is balanced with the necessity to provide shade and shelter, Kalgoorlie has a semi-arid climate with regular 40 degree Celsius + temperatures and little annual rain.
Water provides cooling and delight, allowing all visitors to gather and play without discrimination.
A collection of misting bands interacts with visitors providing drama and spatial variety formed by atmospheric conditions. Calm days creates an ‘ephemeral room’ with canopy hovering over, windy days forms a trail of vapour seemingly generated by the ‘mothership’.
Jets of ground-based water suggest a subsurface existence while allowing direct interaction and playfulness.
Lighting from below interacts with water jets, casting changing patterns and colours on to people and canopy. Bands of white light accentuate the canopy contours providing ambient lighting during the night.
Programmable sound provides local stories and sounds of the environment.
Water is recycled and used for irrigation and all lighting is LED based.
Intensive modelling with shop detailers created unique and complex forms with simple construction techniques allowing for standard industry tolerances and value for money.
Since completion, Saint Barbara Square has been consumed by visitors actively embracing and interacting with the central canopy. It has rapidly become and object of intrigue and delight, creating curiosity while delivering much desired thermal comfort.
