THE Queensland Minister for Education and Minister for Industrial Relations Grace Grace and Impact Investment Group joined Lendlease yesterday to celebrate the official opening of Australia’s tallest engineered timber office building 25 King a $2.9 billion renewal development on Brisbane showgrounds at Bowen Hills.

The $140 million nine storey building involved 3097 individual timber elements, including 33 timber columns on each floor and 52 beams.

Construction involved more than 3090 individual elements

The ­ first of its kind in the Australian property market, 25 King included extensive use of innovative and sustainable building materials.

More than 5970 cubic metres of PEFC certified timber – equivalent to 3402 spruce pine trees – was used in the construction.

Designed and manufactured by Lendlease and sold to IIG, the ground floor plus nine-storey timber commercial tower features open and flexible office space complemented by exposed timber structures to create a contemporary and creative studio environment.

Global engineering ­firm Aurecon occupies 43.5% of the net lettable area, with IIG working with Lendlease to secure new tenants for the remaining office space.

25 King is targeting a 6 Star Green Star rating, a 5 Star NABERS Energy rating and a WELL Core & Shell rating to complement the precinct’s 6 Star Green Star – Communities rating.

Lendlease’s managing director urban regeneration John Burton said the building was the latest example of high-performance workplaces setting new benchmarks in environmentally sustainable building practices with strong connections between timber and human health within the built environment.

“The building demonstrates greener and healthier ways of working,” he said.

“This creates a workplace that lives and breathes a culture of collaboration providing workers with a sense of belonging.”
