What It's
Built For

🎡
Major Public Events
The 20m is built for events that need serious capacity — festivals, expos, agricultural shows, and large community events where one structure needs to do a lot of work.
🏢
Exhibitions & Trade Events
The enormous clear-span floor area is ideal for exhibition stands, trade displays, and product launches where internal poles would be a problem.
Sporting Hospitality Precincts
Covers an entire hospitality precinct in a single structure — race days, golf days, and major sporting events frequently use the 20m as their centrepiece.
🎶
Concerts & Entertainment
High ridge height and wide clear span make it suitable for live entertainment setups, production rigs, and large staging configurations.

How It
Looks

The 20m is a substantial structure — you feel its scale when you're inside. The ridge height of approximately 6 metres creates a cathedral-like interior volume that impresses guests before a single piece of furniture or decor is added. From the outside, it has a strong, clean roofline that reads as professional and intentional on any site. With clear walls, it opens up to its surroundings; with white solid walls, it becomes a complete venue in its own right. Lighting rigs, draping, and production elements all work exceptionally well in the 20m's interior.
