Chris Ross- BSc(Hons), MNZIBS, AssocRICS

Chris’ passion for the built environment was sparked early, inspired by the television series Property Ladder. He began his career in the carpentry trade before pursuing formal study, graduating with a Bachelor of Science in Building Surveying from the University of Ulster in the North of Ireland.

Chris started his professional career in building control before relocating to Aotearoa in 2009. Over the past 16 years, he has worked within a large multi‑disciplinary building consultancy, developing extensive experience as a building surveyor, project manager, and expert witness across a wide range of commercial, residential, and public‑sector projects.

This breadth of experience has equipped Chris with strong technical expertise, sound commercial judgement, and a practical understanding of risk—qualities that underpin the clear, reliable, and trusted advice he provides to clients.

In 2026, Chris was appointed Director of Axiom Building Consultants, where he contributes to the firm’s strategic leadership while continuing to deliver high‑quality building surveying, project management, and expert advisory services. His approach aligns closely with Axiom’s values of technical excellence, integrity, and client‑focused outcomes.
