Diadem is an integrated practice shaping brands and experiences in the built environment.

Since 2000, we have helped people communicate, navigate and engage with branded spaces around the world. We plan, design and project manage signage and wayfinding strategies that connect people to place.

With technical knowledge, trusted experience, in-house expertise and proven processes, we create innovative solutions that add value from the earliest stage.

Our collaborative approach safeguards the interests of clients, preserves the integrity of brands, and delivers smarter outcomes for all.

About Diadem
Our Why

Our why is to shape how
brand experiences, built
environments and people
connect.

We aspire to deliver
enduring solutions that
are equitable, with
sustainability at their core.

OUR INTEGRATED APPROACH

Our difference.

Our integrated approach is one of the reasons clients engage us for projects of every scale. The multi-disciplinary team of designers, project managers and procurement specialists at Diadem collaborates as one team.

Our approach delivers value in the process, integrity in the brand, and certainty in the outcome.

  • 01

    We Design

    When we design, we always consider how those designs can be realised in terms of time, cost and quality. From strategy to concept and documentation, we develop creative innovative solutions that enhance the experience of end-users.

    We solve problems in the real world
    We analyse the real-world problems experienced by people and design solutions to solve them. We consider projects in physical spaces, at scale, with real constraints being used by real people. We do this through real world research and experiences.

    We strive for excellence in design solutions
    We develop exceptional design solutions that challenge the status quo, using creative lateral thinking. We are curious to understand more about our clients and their projects. The more we know, the more we can not only meet their briefs but exceed their expectations.

    We truly collaborate
    We work together with our clients, suppliers and each other to achieve better outcomes than we could ever realise alone. We collaborate with our clients and allow them to co-own the design process. We promote a culture of sharing and transparency. We are willing to lend ourselves to other projects and help across disciplines and across offices. Conversely, we are not too proud to ask for help and leverage the skills and knowledge of our team.

  • 02

    We Procure

    Our procurement experience delivers certainty that our fit-for-purpose specifications will be realised with trusted suppliers. Because of our independence, we’re able to identify the right supply chains to safeguard design integrity and deliver sustainable value.

  • 03

    We Manage

    On brief. On time. On brand. As project managers, we bring rare strategy and foresight in decision making to reduce costs, increase quality, shorten production times and accelerate speed-to-market.

We acknowledge

We honour Aboriginal and Torres Strait Islander People as custodians of Country.

By leaning into practices of First Nations’ rich culture and storytelling, we explore and create connections between people and place.

We are mindful of our responsibility to carry on the legacy of Ancestors and Elders past and present. We commit to learning, sharing our knowledge and collaborating with others to tread lightly for the benefit of future generations.

Our connection to Country grounds us and binds us all.

A collaborative culture.

Around a table.
Across continents.

We find the best solution –
together.

From the way we work as a team across multiple disciplines, to the way we work with our clients and project stakeholders, our strength is our collaborative culture.

It’s not just our unique combination of strategy, creativity and technical expertise which has led to project successes and longstanding relationships. It’s the way we engage with our clients, and empower them to co-own the process.

That always begins by listening, learning, and asking questions. At Diadem we are driven by a need to not only solve our clients’ problems but to push ourselves to find the smartest solution. We thrive on research, constantly educating ourselves and challenging the status quo.

We are collaborative, curious and thoughtful people. We take pride knowing that the work we do not only helps our clients – ultimately it benefits their clients and the wider community.
