Brandon O'Reilly- Owner/Director 

At the heart of our company lies a passion for innovation, craftsmanship, and redefining the construction landscape. Founded by Brandon O'Reilly and Wife Michelle O'Reilly. Brandons journey is built on decades of hands-on experience in New Zealand and Abroad, deep industry knowledge, and an unrelenting drive to push the boundaries of what's possible in mid-to-high-rise construction.

Brandon's career began in the demanding world of heavy commercial construction in South Africa, where he specialized in concrete and steel structures. Armed with a degree in Construction Management and Civil Engineering, he worked at the coalface of the industry—(literally in the trenches) and still does today—gaining firsthand insights that many overlook.

This experience gave him a unique perspective, allowing him to connect the dots in ways that traditional methodologies could not.

Fueled by an entrepreneurial spirit, Brandon, alongside renowned mentor, developer, and businessman Shane Brealey, set out to revolutionize construction methods. Their collaboration led to the development of a groundbreaking in-situ wall formwork system—an innovation that is now transforming the way apartments and homes are built in New Zealand.

​With a commitment to efficiency, sustainability, and superior build quality, we are pioneering solutions that redefine industry standards. Our goal is not just to construct buildings but to shape the future of construction itself.

"Lets change the quality of the housing stock in New Zealand!"

To last 100’s of years.

We soon figured out, it wasn't just a wall system! - it was a Full Structure System!  

Imagine homes built to stand strong for 200-500 years instead of just 70! Picture a future where we plan 200 years ahead, not just 10.  What will our Children's ,Children say of us?
That’s the vision driving us forward.

We are leading a revolution in apartment construction, pioneering cutting-edge in-situ concrete techniques tailored to meet New Zealand’s unique seismic and flooding needs.

Our innovative approach eliminates 30% of the waste traditionally associated with building, creating a more efficient and sustainable process.

Over the past seven years, we’ve refined this system through collaboration with top structural engineers. It has been successfully implemented across a diverse range of developments—from two-Storey terraces to towering 12-storey Highrise apartments delivering 750 apartments and counting.

​Each project we complete is a testament to our commitment to excellence, efficiency, and a bold new future for construction.
