Why Choose ZTC

Built on a Foundation of Expertise

34 Years Experience

Since 1991, we have delivered 400+ projects across 14 countries, combining decades of expertise with a personal approach to every build.

Timber Frame + CLT

Two advanced building technologies produced in one modern factory. One supplier, one contract, one point of accountability.

CNC Factory Precision

Hundegger CNC manufacturing with ±1mm tolerance. Panels arrive ready to assemble - no on-site adjustments, no waste, no delays.

Fast On-Site Assembly

Structural shell assembled in 3–5 days per floor. Weather-tight in weeks, not months - interior works can start earlier.

Building Systems

Two Technologies, One Supplier

Best of Both Worlds
