My skills and passion brought me here, to start my own company, Onyx building. ![B&W Potrait Nick-1](https://www.onyxbuilding.co.nz/hs-fs/hubfs/B%26W%20Potrait%20Nick-1.jpg?width=1920&height=1920&name=B%26W%20Potrait%20Nick-1.jpg) ### Nick Witty Co-owner I started building straight out of school, completing my apprenticeship before moving into a foreman role, where I spent several years helping lead and train a team of five. Orion and I worked alongside each other for 13 years before deciding it was time to start something of our own. That’s how Onyx Building came about, bringing our experience and years of working together into our own business. ![B&W Potrait coming soon](https://www.onyxbuilding.co.nz/hs-fs/hubfs/B%26W%20Potrait%20coming%20soon.jpg?width=512&height=512&name=B%26W%20Potrait%20coming%20soon.jpg) ### Apprentice wanted Apprentice ## Let’s talk about your project Tell us what you’re planning, where the property is and when you’d like to get started.
