While timber has always been part of the construction landscape in Aotearoa, from the
marae to the white weatherboards of colonial homes, contemporary residential
architecture is redefining the concept of wooden houses into something that is less rustic, more revolutionary.
The latest winners of the Home of the Year award, Herbst Architects, have built their career on airy, light-filled wooden homes that make their inhabitants feel close to nature without compromising the natural environment - the majority are on Great? Barrier Island, and therefore off the electricity grid and largely self-sustaining.
The award-winning Piha Bach - dubbed "Under Pohutukawa", as it sits in a grove of the native trees - was, like the others, constructed using only sustainable woods; mostly cedar and poplar ply. "We're interested in the patina that develops through age,
using cedar that fades to driftwood-grey colours, and letting nature do its
thing, instead of plasticising everything," says principal Nicola Herbst.
Erected in 1876, Wellington's old Government Buildings are proof that wooden buildings
can stand the test of time, and larger projects in New Zealand are now also pushing the limits of wood as a structural entity, both functionally and aesthetically - think Noel Lane Architect's refurbishment of the grand atrium at Auckland Museum, the award-winning Waitomo Caves Visitor Centre or Irving Smith Jack Architect's NMIT Arts & Media Building in Nelson, which was the result of a government-sponsored national design competition to encourage the use of tmber in multi-level buildings.
After the 2008 earthquake in L'Aquila, Italy, which left 65,000 people homeless, residents of the small city made it clear to the authorities that they did not want to return to concrete buildings. The construction industry there began focusing on timber reconstruction - not only for single- or two-storey houses, but high-rise structures.
In other parts of the world, they've gone beyond post-earthquake restoration and are designing new buildings completely in wood, using new technology and wood treatments.
Vancouver architect Michael Green, for example, is currently building a 30-storey "woodscraper" as part of the Tall Wood project, a new breed of large, zero-carbon buildings that use wood as a central component in Austria, Norway, and most recently
Melbourne (the Delta Building).
Green is using modern wood materials made of wood fibres, which are stronger than single pieces of wood and eliminate the need to cut down large trees. And, counter to popular belief, heavy timber components pose no greater fire threat than untreated steel.
From the marae to the white weatherboards of colonial homes, contemporary residential architecture is redefining the concept of wooden houses into something that is less rustic, more revolutionary.
The wood industry
The New Zealand wood industry is based around sustainably managed exotic plantation forests of mostly radiata pine and Douglas fir, which cover approximately seven percent of the country's land area.
New Zealand only accounts for just over one percent of the world's total supply of industrial wood, and 1.3 percent of forest products, but supplies almost 20 percent of the Asia-Pacific forest products by value.?Wood products are our third largest export earner behind dairy and meat.
The industry contributes an annual gross income of around $5 billion to the country (three percent of the GDP), and employs 20,000 people.
Wood production volumes are expected to increase significantly in the next decade as
forests reach maturity. These forests are also central to the country's response to climate change, and contribute a host of environmental and social benefits.
