Mass Timber

Mass timber can drive construction’s decarbonisation by delivering projects that achieve strong commercial returns and positive social outcomes. We have been at the forefront of mass timber’s introduction to Australia, and have supoorted projects across the country and to all market sectors for over a decade.

55 Southbank

55 Southbank sets a new precedent for sustainable building design in Australia. It is the world's tallest mass timber vertical extension, utilising mass timber to achieve an increased amount of added floors and a reduce embodied carbon without compromising performance. Located in Melbourne’s Southbank area, its structural strategy leveraged the speed and agility CLT to reduce disruption in one of the city's busier locations.

Vistek were the lead structural engineers for the 10 strorey CLT vertical extension optimising detailing for efficient installation and integrating with other pre-fab systems such as bathroom pods. We worked closely with the mass timber supplier KLH to ensure design, installation and logistics were all carefully considered in the final structural system.

CLT House - Merricks

in collaboration with FMD Architects and Stora Enso, Vistek designed the award winning CLT House. The residential retreat on the Mornington Peninsular leverages the architectural beauty of mass timber with highly bespoke connection design, exposed timber throughout and integrated joinery.

The project has a complex CLT bridge across the parking area and other design features that required specialist modeling to verify but resulted in an wonderful example of the aesthetic and sustainable possibilities mass timber has for residential construction.

ANZAC Station

As part of the massive rail improvements being completed in Melbourne, ANZAC Station is now a new Melbourne landmark. Vistek supported Hess the supplier providing the detailed design for the geometrically complex station entry canopy. The structure also required a complex load analysis dues to the requirements of infrastructure buildings.

Our work extended beyond the structural analysis alone and required a deep understanding of the capabilities of Hess's European manufacturing processes as well as the logistical constraints involved in transporting complex glulam shaped members.

High Street CLT Apartments

Gardiner Architects’ first high‑rise multi‑residential project comprises 13 uniquely designed apartments over a ground-level carpark and café on High Street. Built using prefabricated cross‑laminated timber (CLT), the project achieves an average 8.4-star energy rating, combining sustainability with structural efficiency

The design celebrates individuality: each apartment features its own layout, entry, and orientation, avoiding repetitive corridor-style façades. A central, open stairwell with a south-facing glass-brick façade and a rooftop garden promote interaction and community living.

They layout presented several technical challenges and required a CLT band beam system that was the first of its kind in Australia. High Street Apartments demonstrates CLT’s potential for flexible, high-performance, and liveable housing—pushing sustainable timber construction into the realm of mid-rise urban living.

CLT House - Angelsea

Emma Mitchell Architects designed one of Australia’s first residential homes using locally sourced CLT, showcasing both sculptural ambition and refined engineering. The home’s prefabricated timber panels span up to 10 meters clear, enabling open-plan living and cantilevered roof forms—possible through CLT’s high strength-to-weight ratio.

Structurally, the building integrates CLT with concrete block and brick base, creating a solid yet expressive contrast. The timber structure is celebrated throughout: exposed interior walls, ceilings, and bespoke CLT furnishings—requiring precision coordination between architect and engineer to align panel joins, screw connections, and integrated services.

Thermally, the high-performance CLT offers natural R-value and airtightness, while the sawtooth roof and high clerestory windows optimize passive solar gain and stack ventilation. With materials chosen for sustainability and craft, CLT House balances structural innovation, engineering precision, and coastal comfort—marking a milestone in local mass timber architecture.
