Among the steel and concrete buildings in Brisbane’s landscape, Aurecon’s client, Lendlease, offered an opportunity to be part of something special. Lendlease had an aspiration to construct tall buildings made of timber as part of the AUD$2.9 billion renewal of Brisbane Showgrounds in Bowen Hills. Located 1.6 km from the Brisbane CBD, the precinct is one of the largest urban renewal initiatives in Australia comprising 340 000 m2 of new residential, commercial and retail buildings.

Aurecon sought to create a world class working environment when searching for new office space to relocate its 600 plus people. The timber option submitted by Lendlease gave Aurecon the chance to differentiate itself by creating an environment that puts its people at the heart of its design and thereby supporting the health and wellbeing of its people.

Not only is Aurecon the anchor tenant, but also was part of the creation of 25 King as the structural engineers (with Lendlease), building services and acoustic engineers and ESD consultants for the building, along with architects Bates Smart, interior architects Woods Bagot  and owners Impact Investment Group.

Using engineered timber 

Inspired by the environmental benefits and versatility of timber, 25 King showcases timber from roof to floor. The 9-storey plus ground superstructure utilises a combination of revolutionary engineered Cross-Laminated Timber (CLT) and glulam (glue laminated timber). The glulam is used for the structural beams and columns, and the CLT for the floors, lift shafts and escape stairs.

The engineered timber has a lower carbon footprint than traditional building materials, and is sourced from certified sustainably-managed forests. It also allows for precise offsite prefabrication and safer onsite construction.

Aurecon collaborated with Lendlease for the structural design of 25 King. As part of this process, Lendlease drew on its experience developing other engineered timber buildings, such as International House Sydney at Barangaroo.

It’s about people – WELL Building Standard

Based on Aurecon’s key design principle of providing an environment that supports the health and wellbeing of its people, the challenge was to create a sustainable design that puts people and how they will use the building at the heart.

In early 2020, 25 King achieved Queensland's first WELL Core and Shell Certification at the Platinum level, in addition to its 6-star Green Star Design and As Built rating. WELL is the leading tool for advancing health and wellbeing in buildings globally and uses an evidence-based system that assesses seven categories – air, water, nourishment, light, fitness, comfort and mind. The performance of these building features is then assessed in terms of their impact on the health and wellbeing of the people occupying it.

A 5-star NABERS Energy Base Building rating is also targeted. This will be achieved through features including rainwater harvesting and re-use, enhanced thermal comfort for the workers within and a facade that drives energy efficiency with external shading.

A fit-out creating innovative workforces and spaces that connect to the communities we serve

Aurecon’s tenancy celebrates timber and creates a contemporary and creative studio environment.

At the heart of Aurecon’s wellness culture at 25 King, is a wide staircase at ground level leading to an open, communal space with booths and meeting spaces framed by greenery and bathed in natural light.

Creating spaces where people want to spend time and engage with others, inevitably leads to a more collaborative and innovative workforce.

A world-class building brought to life 

25 King is currently the tallest and largest* engineered-timber office building in Australia. A co-creation between Lendlease and Aurecon, together with Bates Smart, 25 King is a world-class building of the future.  

Construction finished in October 2018 with Aurecon moving its 700 Brisbane staff in early November 2018.
