We believe sustainability is multi-faceted; it’s about taking responsibility for the environmental impact, cultural heritage, economic viability and social significance of our work. Our designs are resilient to what-ever the future holds. We create projects that are sensitive to a changing climate, responsive to technological developments, and built to contribute to healthy and happy communities for generations to come.

1 Blight Street Sydney | Commercial architecture

1 Bligh Street
A full-height naturally ventilated atrium opens out into public space, where conditions are tempered by relief air from the office levels, and heated in-slab using waste heat from the tri-generation plant.

Natural ventilation

Natural ventilation is a key component of the passive design principles embodied
in our work, reflecting our commitment to provide thermal comfort and healthy indoor environments through the sustainable use of natural resources.

Sunshine Coast University Hospital | Health and public architecture

Sunshine Coast University Hospital
The Sunshine Coast University Hospital is the largest public healthcare facility in Australia to earn 6 Star Green Star Healthcare Design v1 and As-built v1 ratings.

Key features of the design include a large integrated central Courtyard and the Outdoor Room designed to take advantage of the local climate, coastal lifestyle, and the healing properties of natural air and light.

Research into biophilia reveals improvements in worker health and productivity, and patient recovery times, when environments incorporate living plants.

Queen Elizabeth II Courts of Law | Justice and public architecture

Queen Elizabeth II Courts of Law
Thermal mass can be used passively where it is merely exposed to the internal environment of the space and exchanges heat naturally between itself and the air. When combined with adequate insulation significant energy savings can be achieved.

Thermal mass

Concrete and other dense materials such as stone and fibre cement absorb and store thermal energy through their mass, thermal conductivity and exposed surface area. 

Loreto Mandeville Hall | Education architecture and schools

Mandeville Centre Loreto Toorak
The pinwheel concept that informs the design of the Mandeville Centre animates and orders the building program around a central atrium space drawing natural daylight within.

Geometric modelling of buildings in response to solar geometry enables controlled solar exclusion or harvest while allowing ingress of daylight when needed.

1 Bligh Street Sydney | Sustainability

1 Bligh Street
A black water recycling system treats up to 100kL/day to a high quality for use in toilets, urinals and cooling tower make-up, while rainwater is harvested for landscape irrigation.

Water management

We take an integrated approach to water management in projects of all scales to help to build a more resilient water cycle for our cities.

241 O'Riordan Street | Commercial architecture

End-of-Trip Facilities
Energy can be conserved through providing staff in commercial buildings end-of-trip facilities to encourage alternative modes of transport to and from work.


Cities and the buildings they contain are among the largest users of energy and the greatest contributors to climate change. Energy conservation measures improve the efficiency of our buildings and equipment, particularly through reducing energy loss from heated or cooled environments.

The Macquarie University Incubator wins Green Good Design 2018 award | Tertiary architecture

Macquarie University Incubator
Timber was chosen as the main construction material for the Incubator for its capacity to be beautifully engineered, swiftly fabricated to a high quality, and for its potential for future dis-assembly and relocation.

Winner of the Sustainability Award for Education and Research, 2018.

We select materials that are reusable or recyclable with low embodied energy and no unhealthy bi-products. Careful detailing reduces material waste and leads to future disassembly rather than demolition.

1 Blight Street Sydney | Commercial architecture

1 Bligh Street
The sweeping northern steps at 1 Bligh makes a real public space that encourages people to linger and sit down – an objective for all city place makers.


Projects that have the potential to incorporate social amenities and cultural opportunities in their buildings, landscapes and spaces will build social resilience and enhance sustainability.
