UNEX provided 185LM of Hampton balustrades and a custom 3.8m stair screen, engineered to meet C5 loading and NZ Building Code standards. Designed for safety, compliance, and aesthetics, our solutions contribute to this modern, four-storey learning environment.
At Onehunga Primary School, a fresh, modern learning environment has taken shape - one that’s not just visually striking but also built for safety, durability, and long-term performance. As one of New Zealand’s tallest primary schools, its striking four-storey design combines modern aesthetics with functionality to support flexible learning environments.
UNEX contributed to this award-winning project by providing aluminium balustrade and screen solutions that prioritise safety, compliance, and style. Designed by Jasmax and brought to life by Watts & Hughes Construction, this project showcases the power of collaboration and innovation.

UNEX’s Contribution to This Project
For this ambitious development, UNEX supplied 185 linear metres of Hampton Balustrades in Dulux Duratec Sandstone Grey, engineered to meet C5 loading standards, ensuring durability in high-traffic educational spaces. Additionally, we delivered a custom 3.8m-high aluminium stair screen, powder-coated in Dulux Duralloy Champagne Kinetic, providing both safety and a sleek architectural finish.
A site-specific PS1 design, tailored to the unique characteristics of this project, ensures full compliance with New Zealand Building Code requirements and Ministry of Education guidelines.
