“Frames are stronger and better manufactured than the previous supplier. They look great!”
Gullwing Tunnelhouses
The Gullwing Tunnelhouse is engineered for year-round production in warmer Australian climates. Automated gullwing roof vents open and close in response to weather conditions, protecting your crops in rain, wind and cold, and ventilating when the heat builds. The result is a stable growing environment, stronger yield consistency and less time spent reacting to weather.
Built for warmer climates
Ventilation is the difference between a productive season and a stressed crop. The Gullwing solves this with a vented roof design that maximises passive airflow, paired with Ridder automated vent technology that responds to temperature and humidity changes without manual intervention. Whether you run propagation, vegetable production or cut flowers, the structure creates a microclimate you can rely on through summer heatwaves and unpredictable storms.
Australian made, built to last
EnviroTec manufactures the Gullwing Tunnelhouse at our Yandina facility on the Sunshine Coast. Every frame is cut, drilled, bent and rolled in-house, using galvanised steel and premium commercial-grade covers. Structures we built in the 1990s are still standing today. That is the kind of return on investment commercial growers need from a greenhouse.
Available as a kit or fully installed
Standard widths are customisable and internal partitions can create zones for different crops or growth stages. Request a quote to discuss your site, your crops and the Gullwing configuration that will deliver the yield consistency you are after.

Automate the vents
Australian weather changes fast. With automated roof vents, your Gullwing Tunnelhouse responds to conditions as they shift, opening for ventilation when the heat builds and closing against rain, wind and cold. No manual intervention, no missed windows, no crop losses from a vent left open overnight. Your crops stay protected, your climate stays stable, and you get the predictability that year-round production depends on.

Testimonials
Frank
Chicken farmer in NSW
“All the structures here are provided by EnviroTec. We used EnviroTec for multiple products, whether it is a grow tunnel, the shadehouse we’re in, our prop houses, or even just netting repairs and structures.”
James
Cedar Hill Group
“When I first approached the property after a hail storm had struck here with wind and rain, I expected everything to be flat. The shadehouses were looking as they always do. I was very impressed.”
Jack
“EnviroTec builds the best structures. They have been through many storms and cyclones, and we’ve never had any issues. We can put our plants in their structures and grow the best plants. It all starts with a structure.”
Ted
QIF
“We’ve purchased a whole range of structures from EnviroTec. When you are in a growing environment with all sorts of elements at play, it is important that things are structurally sound. A number of our structures are quite old and have held together wonderfully.”
Tom

“EnviroTec has been the go-to place for us for years. David has always gone over and above for us. We’re not a huge client, but we feel like whenever we ring up, EnviroTec treats us with the same respect as they would some of their biggest clients.”
