Atlassian has outlined the design for its new $1 billion-plus headquarters, the world's tallest hybrid timber building to date, which will consume half the carbon in construction and half the energy of a conventional equivalent building after its planned opening in 2025.

The locally based, Nasdaq-listed software company has confirmed plans for its 180-metre, 40-storey Sydney office tower – first reported by The Australian Financial Review in February – and revealed a steel and glass skeleton will wrap around the building divided into different vertical zones.
