TOKYO -- Japanese general contractor Obayashi said Wednesday that it has received an order to construct the world's tallest timber building in Australia, a 182-meter sustainable skyscraper combining wood and other materials to house the Sydney headquarters of software company Atlassian.
The 39-story Atlassian Central structure will stand adjacent to the Central rail station in Sydney's Tech Central innovation and technology precinct. The mixed-use tower with a floor space of 75,000 square meters also will be home to a hotel and retail stores.
Obayashi's joint venture with local construction company Built has been commissioned by Australian real estate firm Dexus to build the tower, which is slated for completion in 2026.

The building, to carry the highest level of environmental certification, will be made of steel-reinforced, low-carbon concrete from the basement to the seventh floor, with cross-laminated timber and a steel exoskeleton used for higher floors.
The project aims to limit carbon dioxide emissions during construction -- from materials procurement to completion -- to less than half of those for a conventional building. For operation, the tower is expected to be powered by 100% renewable energy.
Obayashi is among the Japanese companies tapping the trend of building wooden skyscrapers in Australia, where interest in achieving net-zero emissions is strong and fire safety codes are less strict than in their home country. Sumitomo Forestry and NTT Urban Development are creating a hybrid timber building in Melbourne with U.S. real estate firm Hines.
