Timber Office Tower Proposed for Brisbane

Brisbane, Australia – 10 February 2017

Continuing the trend for innovative timber construction in office building design, 5 King is a high-performance commercial building that will become the tallest engineered timber building in Australia, according to developers. The 52-meter tower, located in the Brisbane Showgrounds development, has been designed by Bates Smart for Lend Lease. Developers for the project also claim that it will also hold the title for the largest gross floor area (GFA) for an engineered timber office building worldwide.

In blending tradition with innovation, architects have designed a building that addresses the fundamental need to connect to nature and preserve the environment. The development utilizes cross-laminated timber (CLT) and glue-laminated timber (Glulam), together combining the structural strength of concrete and steel with a low carbon footprint.

Bates Smart Director Philip Vivian said, “We see timber buildings as the next generation of workplace for a creative class looking for rich environments that enhance well-being and productivity. The timber construction recalls the vernacular ‘Queenslanders’...to create a site-specific and innovative tall building that connects with nature.  The buildings ‘veranda’ will be an edge condition that maximizes connection with the environment.”

At ground level, a substantial 54-meter-long timber colonnade will be lined with cafés and restaurants. The side-core design offers generous 1,588-square-meter net leasable area (NLA) floor plates, with a total of 14,921 square meters of NLA over 10 floors. The glass façade on the main south elevation maximizes natural daylight, while sunshades on other façades reduce energy consumption to further reduce the building's carbon footprint.

Inside, exposed timber structure and services create a contemporary studio environment that balances well-being with creative collaboration space. The floor plates integrate a six-meter by eight-meter module grid of Glulam columns and exposed ceilings with visual grade CLT cladding to the core, underpinning the honest expression of the structure.  Exposed “K” bracing on the floor plate perimeter provides additional structural support.

The building will be the future home of global engineering firm Aurecon. In addition to providing structural and building consultancy services, the company has committed to lease four of the nine office floors.

Construction is set to begin mid-2017, aiming for a target completion date of late 2018.
