"Will probably settle in to become a heritage icon in Brisbane."
"Now that's how to disguise a carpark. Makes a great contribution to the public realm. Vivid, joyful - makes excellent use of contemporary steel design and fabrication technology."
APPLICATION OF PROJECT:
The vertical façade works is part of the redevelopment of the wintergarden shopping centre.. This façade creates a uniform streetscape, providing a visual barrier to a number of existing carparking levels and different buildings along Queen Street Mall.
Wintergarden redevelopment architectural façade on Queen, Elizabeth and Edward Street, Brisbane. The architectural intent of the façade is to create a three dimensional depiction of a winter garden painting To achieve this, the façade consists of multi layers of rigid cladding supported by a modular structural steel grillage frame. In addition to the cladding panels, the façade consists of a number of steel frame, stainless steel cald butterflies which cantilever from the grillage.

Overview of Cablenet Structures
The modern cablenet structures burst on the international scene with the Expo 67 German Pavilion constructed in Montreal, Canada.
This was a larger version of the cablenet roof prototype designed by Frei Otto's team and used now to house the IL at the University of Stuggart.
Australia can bost a very early cable net structure in the Sidney Myer Music Bowl in Melbourne.
The next structure, and the most famous is the impressive stadiums for the Munich Olympics designed by Frei Otto.
Highly stressed cable trusses are also used to support flat glass surfaces now common for facades.
Other Structural Forms - Cablenets, Glazing, Facades, Spaceframes
The LSAA has groups of members interested in cablenets, high technology glazing and facades.
In fact one main reason for the creation of the LSAA from the MSAA was to cater for the growing number of projects which involved large glazed areas being supported by pretensioned cable truss systems or cablenets.
In modern times, when the overall energy usage for the life of a building is taken into account, the use of high technology facades will become more important. There is also a growing use of "green facades" or vertical gardens.
The traditional spaceframe structures are becoming rarer - those with many small elements that are man-handled and connected together on site. Labour costs and erection times are now outweighed by fewer larger assemblies that can be installed quickly by cranes.
The LSAA would welcome articles and links to projects in this category.
Taronga Zoo Chimpanzee Enclosure - Sydney
APPLICATION OF PROJECT: Separation Enclosure for Chimpanzees.
The Taronga Zoos’ chimpanzee troop is one of the largest captive groups in the world with recognized wild behavior patterns and a sophisticated social hierarchy. With its population including four maturing sub-adult males jockeying and promoting themselves within the group, the zoo cited a need for the construction of a fully enclosed and semi-transparent separation paddock within the chimpanzee exhibit to allow the chimpanzees to be easily divided as needed, without moving them to an entirely new location, and thus avoiding potential commotion.
The Seperation Enclosure:
- facilitates the introduction of new chimpanzee females to maintain the genetic pool.
- provides the necessary infrastructure for the current troop management strategy and philosophies.
- permits the troop to remain outside in summer unsupervised where this was previously not possible.
- maximizes viewing time for the public.
