The exposed cut sandstone face of the former Paradise Quarry aligns with the proportions of a planned courtyard, inspiring the ‘Quarry Garden’— a sunken central space with a carved out pool, set within the sandstone shelf. A mosaic of endemic plantings and wet-dry transitions is incorporated into the design as ‘layered bushland’, with the ‘Quarry Pool’ becoming an extension of this landscape.
The mid-rise podium, built in demolished concrete, masonry and locally sourced recycled stone, wraps around this courtyard, with elevated street-facing apartments optimising solar access and cross-ventilation. The tower stretches above, smoothed and shaped in response to the wind and sun. Layered surfaces and tonal variation are expressive of sedimentary processes, and the façade is clad with natural and glazed terracotta panels, which subtly reflect the changing patterns of the day.
Water is celebrated through rills and rain gardens around the building base, along street fronts and through the central garden, filtering stormwater throughout. Vegetated podium rooftop apartments and gardens create a natural habitat for butterflies, bees and birds, and perimeter walls complement the character of Pyrmont. Like sandstone itself, the design acknowledges the passage of time.
After 100 years of taking from the Pyrmont landscape – defined by the resilient sandstone ridges and wet gullies of Gadigal Country – our approach looks to understand what we can give back; how we can renew these diverse micro-ecologies while creating a thoughtfully dense urban footprint, responsive to Sydney’s growing residential demands.


A remnant wall of the original Pyrmont quarries is made from the same stone used to build early colonial Sydney.
The building massing is divided into three stratum as a direct response to the stratified nature of sandstone geology. By translating the temporal qualities that shape sandstone formations into architectural expression, a dialogue is created between built form and geological context.

Materials are selected for their ability to weather gracefully over decades. This temporal quality manifests a living building that is adaptable to its geological context, reinforcing the connection between human-made and natural systems.

Within the tower form, pale terracotta panels have been selected to mimic the gradual shifts in material colour and texture found in sandstone formations with earth tones drawn from local sandstone including pale ochres, umbers, and warm greys establishing a chromatic continuity with the geological context.

Moist, sheltered podium sinks evoke the cool gullies of Pyrmont’s precolonial escarpment, grounding the architecture in Country. The central courtyard reimagines the abandoned sandstone quarry as an inhabited void, a carved-out landscape where water, stone, and sky converge to create a quiet gathering space. Lightweight, exposed upper levels host hardy coastal vines, heaths and grasses, creating biodiverse roofscapes that absorb heat, move with wind and support habitat. The result is a climate-responsive, non-extractive landscape that honours local Country, weaving ecological resilience and geophilic architecture into a living, cooling, abundant place.
