Meet our Team
Christos: NatHERS Sustainability Assessor
Since launching his energy rating journey in 2015, Christos has evolved into a leading specialist in Environmental Sustainable Design (ESD). Having completed thousands of projects across all Australian States, his experience is unparalleled.
Christos holds a Building Sustainability Assessor Certification and a Diploma in Building & Construction, making him uniquely qualified. This dual expertise as an accredited NatHERS Assessor and a seasoned builder is the single most important factor in securing compliant designs that actively control and reduce your construction costs. He translates complex 7-Star requirements into straightforward, budget-conscious building solutions.
Christos’ Quote:
“As both an Assessor and a Builder, my view is simple: 7-Star NatHERS compliance is non-negotiable, but overspending is a choice. My role is to find the strategic design path that achieves the required sustainability score while actively minimizing your construction costs. We don’t just pass the code; we protect your profit margin.”
