Embodying sustainable design through natural, local materials


The project

Completed in 2024, 90 Devonport Road is New Zealand’s largest mass timber office building—a collaborative, sustainable design feat led by architects Warren and Mahoney.

 

“The brief was to create a high performing, connected workplace for Tauranga City Council,” says Arron O’Hagan, Warren and Mahoney senior associate, designer and technician. “Our design sought to encourage staff to come together in one central location as a place of safe anchorage for all people and cultures, becoming a wellspring of wellbeing and a beacon of sustainability with the intrinsic value of connection to the surrounding whenua (land) at its core.”

 

The design also intended to achieve a 100% reduction in embodied carbon, a 6 star Greenstar rating, and a WELL Gold rating—successfully accomplished by adhering to strict sustainability practices at all stages of the design and construction process.

Built around a central interconnected CLT timber stair, the fitout was designed to encourage movement and activity throughout workspaces across multiple floors.

 

“Each floor protects an east-west viewshaft that overlooks important cultural landmarks and connects to the preserved Pohutukawa tree in the northeast corner of the site. With the mass timber backdrop of the base building, the fitout materiality focussed on the use of natural and locally sourced materials, responding to the local colour palette through bio-mimicry and heavily planted areas of respite throughout,” Arron explains.

 

To ensure a high level of acoustic comfort and privacy throughout the workspaces, Warren and Mahoney engaged Autex Acoustics® to provide acoustic solutions that would allow them to meet the brief technically, aesthetically, and sustainably.

 

“There’s a strong synergy between Warren and Mahoney (WAM) and Autex Acoustics. Both are known for pushing boundaries and striving for innovation, and both share a deep commitment to sustainable design and materials. Sustainability is a core value embedded in all of WAM’s work, and Autex Acoustics mirrors this ethos as stewards of environmentally responsible innovation,” says Anton Agnew, Autex Acoustics account manager.

The solution

“During the development phase of the project, it became clear that Embrace™ would be a perfect fit for this project. 90 Devonport was set to become New Zealand’s largest mass timber office building with ambitions of a 100% reduction in embodied carbon and a 6 star Green Star rating, while the interior fitout for Tauranga City Council is targeting a WELL Gold rating,” Anton says.

 

Thanks to LumaWool™, the New Zealand strong wool material used in Embrace, it achieves a carbon negative footprint of minus 8.6kg CO2e. Consequently, Anton says, it felt fitting to discuss the opportunity to integrate Embrace into such a unique and sustainability-focused fitout.

 

“We chose the natural wool product—Embrace installed over ReForm™, paired with Abodo timber—as an intuitive response to showcase innovation, while reducing the carbon footprint in the creation of a feature wall within the public facing gathering spaces.

 

Of course, in a government building with such a significant amount of exposed timber, acoustic privacy is a high priority. To maintain the required level of acoustic treatment without sacrificing the warm, natural timber aesthetic, WAM took a strategic approach.

 

“Our first strategy was to optimise meeting rooms and only build multi-purpose spaces that would be well used. The second strategy was to build modular pod rooms, independent of the structural grid, that could perform to a high acoustic standard and adapt to a variety of uses, including video conferencing, private meetings, and public events,” Arron explains.

 

Alongside Embrace, other carbon neutral acoustic solutions including Frontier™, Groove™, Composition®, and a bespoke boomerang-inspired Horizon™ ceiling were also specified—achieving the acoustic requirements whilst supporting the project’s aesthetic and cultural purpose.


The result

As the pioneer project for Embrace, both WAM and Autex Acoustics were thrilled to showcase this acoustic design innovation.

 

“It was exciting to be working with Autex Acoustics during the early testing of what would become Embrace, exploring the capabilities of a new product in a highly visible environment. The sampling and shop drawing process was smooth as we were able to move quickly from ideation into specification with little delay,” Arron says.

 

Through the 90 Devonport Road project, it’s clear that collaboration with local suppliers and the specification of natural materials has a positive impact on the success of large, complex, sustainability-driven projects—an outcome Arron hopes will inspire other design professionals across Aotearoa.

 

“Showcasing so many innovative products by local suppliers alongside the beautiful timber structure, while also delivering a high performing workspace with staff wellbeing at its core, is what we are most proud of. Creating a workplace that encourages people to come together and do their best work, while fostering a sense of community by bringing people into the city centre, is another huge success for this project.”
