NJW Designs has worked on more than 120 theatre shows in the past 12 months, including popular new production Harry Potter and the Cursed Child, The Book of Mormon, The Lion King and Sovereign Hill's new show Aura.

Business owner Nathan Weyers said the business had grown exponentially since it first began two years ago and staff were working to put in processes to respond to increasing demand for services.

The team of around six permanent staff work with theatre companies to design production sets before manufacturing is completed in their Wendouree workshop. It is then put into a truck and sent to the theatre.

"None of the theatres are the same. One of our major jobs at the moment is making sure theatre shows fit in to other venues," Mr Weyers said.

"We did that for 12 months with Harry Potter in Melbourne before they came."

Mr Weyers' work in theatre first began as a teenager growing up in Ballarat and around BLOC Music Theatre.

He helped build sets for BLOC shows with his grandfather Jim Muller and designed his first production set at 16 with the help of his uncle Damian Muller.

He went on to study theatrical design in Perth at the Western Australian Academy for the Performing Arts (WAAPA) and spent the next ten years on tour with musicals around the world, including Mary Poppins, The Lion King, Phantom of the Opera and Aladdin.

"I would set up the shows, work behind the scenes and run the automation in the shows of a night, about eight shows a week. Then I would move them between cities and countries," Mr Weyers said.

"I was always on the move. It was pretty wild. I got put into accommodation in the cities and I constantly shifted around. I did miss a lot and never got to go home. I always missed Christmas and always missed Easter, but that is life on big touring productions. I wouldn't change it."

Running NJW Designs, Mr Weyers is now home more often than he used to be, but continues to travel frequently to set up shows around the country.

With increasing demand for services, Mr Weyers said the team would look to employ more staff at busy periods and increase workshop space.

"There is a massive lack in the industry of businesses that do the entire service. That is what we are trying to create," he said.

"Technically companies can come here and we look after their design, manufacture and installation and they don't have to go anywhere else."

NJW Designs is a finalist for the 2019 Ballarat Business Excellence Awards.
