International House a Grand Prix of Sustainable Design
The prestigious 2017 Australian Timber Design Awards Grand Prix went to arguably the most prestigious building Australia has seen for a long, long time – International House, located in the Barangroo precinct in Sydney.
This is Australia’s first and largest commercial engineered timber building and stitched together with Cross Laminated Timber (CLT) and Glue Laminated Timber (Glulam). It’s not just the materials though that make it special, it has a striking look inside and out, and it displays the outstanding and sophisticated foresight of architect Jonathon Evans of Tzannes Architects.
DesignMake and Tzannes used the CLT and Glulam building materials and technology to deliver a remarkable building that comes at a fraction of the weight of a steel and concrete structure.. and delivered quicker! Using these materials have given not only Tzannes Architects a new outlook and skills, but also Lendlease and DesignMake. They have had to learn new ways to design and make.
The structural elements of the building were prefabricated which involved a steep learning curve for everyone. It’s beauty as a finished product was testament that a commercial building in Australia could be made sustainably, quickly and still showcase aesthetics.
“The architecture of International House Sydney reflects a new form of beauty,” said Alec Tzannes, the principle architect, “beyond shape and surface, its deep design renewing architecture’s role to serve the greater social purpose of lowering carbon emissions.”
More than 2,000m3 of CLT was used for the floors and cores, and 930m3 of glulam was used in the columns and beams. The towering two-storey wooden pilasters, which support the CLT, are reclaimed ironbark timbers.
Now in its 18th year, the Awards promote and encourage outstanding timber design. They are open to builders, designers, architects, engineers and landscapers: to anyone involved in the design or building of structures that feature timber. A Rising Star Award is available to students and entrants aged 35 or under.
International House has also won international acclaim; the International Architecture Awards, awarded by two leading design institutions The Chicago Athenaeum and The European Centre for Architecture, Art, Design and Urban Studies.
This makes it six major international design awards for Tzannes in the past two years.
