The Directors are CAR’s core resource. Individually they have leading-edge expertise in specific aspects of the built environment. More importantly, when working together their expertise is amplified and leads to interdisciplinary insights.

The Directors of CAR manage the company, ensuring that it is professionally and efficiently run, and resourced to meet clients’ project delivery expectations.

Over the years the Directors have collaborated on hundreds of projects. For each new project CAR assembles a team made up of Directors and Associates, with external consultants when required, providing the range of in-depth expertise to focus on client-defined questions.
