30 years of asking, ‘what if?’

Tzannes is an Australian studio for architecture, urban and integrated design based in Sydney. The practice’s creative thinking and innovative, sustainable and enduring architecture has established our reputation as a leader in the field.

Our work is about specific responses to every client and every project, not about preconceived ideas, style or approach. We consider each brief an opportunity to apply architectural skill, creativity and innovation to solve our client’s design problems, but also to delight and to inspire.

Tzannes’ distinction is our ability to work across all scales and project types. The breadth of our skills and experience, the profile of our talent and technology enable us to service significant projects with the efficiency and confidence of a large practice. At the same time we are known for passion, curiosity, attention to detail and close personal relationships with our clients on commissions that are of great emotional value but modest in scale.

Our clients and consultants appreciate the firm’s collaborative nature, intellectual rigour and an ethical approach. At Tzannes, these same values are fostered by the way we work as a team in an open floor studio with a shared design culture, an open exchange of ideas and an ethical employment system.

Creative and effective

Our design is research-based. We develop innovative and precise solutions that balance the (often competing) objectives of the approving authorities with those of our clients. Tzannes build on a detailed understanding of the client’s brief and ambition, as well as the environmental, economic, planning and urban design contexts. We use a range of design techniques and analytical tools to bring the project to life. All aspects of the design are integrated from the outset, providing the client with the best possible outcome and transparent control over time and cost.

Over the past three decades our work has been recognised by our clients and awarded by the profession on public and private projects as varied as homes and apartments, hospitality and education to major urban and commercial precincts, public spaces and street furniture.

Environmentally Sustainable Design

An integrated approach to environmentally responsible architecture is an essential part of the Tzannes design culture. We consider sustainability as the only way to produce enduring buildings and thriving communities that deliver positive social and environmental outcomes.

Environmental performance is understood holistically at Tzannes, for the full life cycle of the project, with each building directly responding to its specific natural, social and economic circumstances.


Expertise and Collaboration

Every project Tzannes undertake has a collaborative design process as its foundation.. And it is the directors of the practice who lead and promote this approach. We are known for working as a team across all projects, thereby avoiding silo-type thinking and encouraging ideas and solutions to come from unexpected lines of inquiry. This methodology extends to the entire studio: the team meets regularly for joint project reviews; key stage assessment panels; professional development and guest speaker sessions; or to simply talk and share new thinking.

Our design philosophy means that we address each brief with distinctive and relevant propositions, creating artefacts in the process that have an appreciating value in every respect – culturally and materially.”

“Architecture is the perfect combination of creative expression and technical skill. There is often a rich layering of elements throughout the design of a project. To me, the most beautiful spaces appear the simplest, enhanced by a refined palette of materials. We are passionate about what we do and the exceptional team at Tzannes take great pride and meticulous care in all aspects of each design.”
