mission
At TNKgreen, we believe architecture shouldn’t just sit on the earth — it should come from the earth. Our purpose is to pioneer a mainstream design revolution where regenerative principles and biobased materials take centre stage.
We are here to challenge the status quo. Through rigorous research and low-carbon development, we demonstrate to the modern marketplace that biomaterials offer a healthier, more durable, and architecturally superior future. This commitment to pushing boundaries earned us a place among the Top 100 Sustainable Architects and Designers of the World in 2024.
Our blueprint goes beyond minimising harm; we design for active regeneration. We create beautiful, enduring spaces that breathe, heal degraded environments, and anchor a sustainable legacy. Hand in hand with our clients—and the local communities we empower through technical workshops—we aren’t just building for today; we are cultivating a thriving collective movement for generations to come.

Meet the Team
Head designer Hernes Kruger brings over two decades of architectural excellence to the forefront of sustainable design. A 2004 architecture graduate from the University of Pretoria, Hernes built a diverse professional foundation with top-tier firms, delivering high-impact projects across the corporate, residential, retail, hospitality, healthcare and religious sectors.
Rooted in an upbringing within the industrial landscape of Sasolburg, Hernes developed an early, acute awareness of the built environment’s ecological impact. This insight inspired him to found TNKgreen—a practice dedicated to alternative construction methods and regenerative principles. By merging proven design fundamentals with cutting-edge sustainable practices, Hernes guides clients through a collaborative, transparent process to realize a beautiful, greener future.
Marketing Director & Partner Zoe Graham grew up in Mafikeng, where she learned that the strongest structures are rooted in community and shared purpose. That insight became the foundation of her two‑decade career; bridging branding, operations, and human‑centred strategy.
After earning her Honours in Information Design from the University of Pretoria, Zoe spent twenty years across fintech, healthcare and renewable energy. Now a partner at TNK Green, Zoe leads branding, sales and client enablement, while offering training and facilitation. She brings her intuitive pragmatism and low‑ego approach to every conversation.
“I believe in building brands that are not just visible, but valuable to communities, to people, and to the earth.”
