PROJECT INFO





Alton’s proposal is deeply informed by a Connecting with Country Strategy, developed in collaboration with Everick Heritage and Dharug artist Leanne Redpath. Inspired by the themes of Tree, Water and Life, the architectural concept explores the interwoven relationship between people, place, and nature.


The form of the buildings, the landscaped link, and the integration of water throughout the site collectively shape an immersive, site-responsive experience. At ground level, the through-site link serves as a connective green spine—merging native planting with urban walkways—enhancing ecological connectivity and celebrating non-human kinship with Country. Water becomes a central design element, carving movement across the site and creating a sense of elevation and rhythm.


Architecturally, the towers rise with sculptural clarity, while the podium is composed of vertical brick blades, drawing on the site’s natural topography and echoing the flow of water and the rhythm of the landscape. This layered approach to massing ensures the development is both distinctive and deeply respectful of its context.



Spanning 17,623 sqm, the masterplan comprises four elegantly stepped towers ranging from five to 25 storeys, designed to balance density with open space and environmental responsiveness. The development includes:


  1. 615 apartments, including 169 affordable units (15%) managed by a registered community housing provider for a minimum of 15 years.
  2. Over 8000 sqm of retail and commercial space across ground and upper podium levels.
  3. More than 900 car spaces across two basement levels.
  4. 6926 sqm of private open space and 1100 sqm of internal resident amenity.
  5. A publicly accessible through-site link, designed to connect the site to Castle Hill’s green corridor network and Metro infrastructure.
