Standing as “Australia’s tallest engineered timber office building”, 25 King takes the synthesis of advanced timber engineering and environmental construction to new heights.
More importantly, the mid-scale office building’s forward-thinking sustainability imbues a world-class working environment that supports the health and wellbeing of its people.
In a Brisbane landscape dominated by steel and concrete, this elegant head-turner features timber from roof to floor. The complex design and construction is replete with sustainable building materials including cross-laminated timber (CLT) floors and walls, as well as glulam structural beams and columns.
The CLT is sourced from certified sustainably managed forests and boasts a lower carbon footprint than traditional building materials.
On the HVAC front, the nine-storey building utilises a low-temperature variable air volume (VAV) solution that allows for a reduction in the total air volume required and fan power consumption. The low-temperature VAV system is served by a chilled water plant comprising two water-cooled, high-efficiency screw chillers.
Three cooling towers, seven AHUs, and two outside air preconditioning units (PCUs) complete the system.
Aurecon collaborated with Lendlease on the structural design and award-winning firm, Bates Smart, took care of architectural design.
The team brought out the wellness objective of putting people – not buildings or technology – at the centre.
“Architecturally, the use of natural materials – as opposed to concrete and plasterboard – creates a happier and healthier workplace,” says Bates Smart director Philip Vivian.
“With the timber structure and floor soffit exposed, as has been achieved at 25 King, the office environment glows with the material’s warmth, and better connects building occupants with nature.”
25 King was awarded Queensland’s first WELL Core and Shell Certification at the Platinum level, in addition to 6 star Green Star Design and As Built ratings.
As part of the $2.9bn renewal of Brisbane Showgrounds in Bowen Hills, the brownfield project includes 340,000m² of new residential, commercial, and retail buildings, together with new development of 76,000m² of RNA-attained land.
