A changing skyline reflects a city's growth and for many cities today much of that growth is the result of urban renewal. As light and medium industry moves out of the inner city and away from port areas, former industrial land is now becoming prime real estate.
Jacksons Landing in Sydney is one such area. Developed by Lend Lease Development and project managed and constructed by Bovis Lend Lease, Jacksons Landing is an 11.7ha waterfront residential development occupying a historic position at Pyrmont Point. Formerly the site of the Colonial Sugar Refinery, Jacksons Landing is now classified as a mixed-use area, offering premium inner-city living along with more than 25,000m² of commercial and retail space.
The development will eventually incorporate many buildings designed by a number of architects. For Knox on Bowman, which features on these pages, architect Alexander Tzannes was commissioned to design 24 boutique apartments on a sloping site. The location offers extensive views north across a park to the harbour, and south to Blackwattle Bay. The site also borders two streets and the design needed to provide a pedestrian thoroughfare on the west side.
Tzannes says the uphill slope of the street helped determine the decision to use a sandstone wedge to form the base of the building.
"This sandstone is typical of the area, and its use is a reference to the original rocky outcrop on the site," he says. "As well as anchoring the base of the building, it links to the topography of the site and creates a strong sense of a building being formed out of the land."
Tzannes says the sandstone also complements the public domain the zigzag stepped path that links the upper and lower streets. Both the building and the retaining walls of this thoroughfare feature random cuts of sandstone, rather than bookmatched pieces. This provides an economical cladding solution, and the random grain creates an edgy, contemporary feel.
An aluminium, steel and zinc structure was designed to float above the solid stone base, creating two distinct elements to the building.
