Reliable Greenhouses Built for Australian Growing Conditions
From seedlings to full production, our structures deliver controlled climates, exceptional strength, and long-term value.
Greenhouses Designed to Protect, Improve, and Extend Your Growing Seasons
Greenhouses are useful structures that improve and shield your flowers, fruit and vegetable crops, and other prized plants from the potentially harsh forces of nature. Growing seasons can be extended and even improved when your plants don’t have to deal with extreme weather, external physical damage, or pests.
Give your operation the benefit of 35 years design and build experience with Croft Structures’ polythene greenhouses. We have the knowledge, manufacturing experience and high quality of customer service across our team to partner with you.
From large greenhouses for commercial sales applications to small structures for the medium sized home gardener or grower, we have greenhouses for sale to suit your needs.
Greenhouse Tunnels
Our crew of fully licenced professionals design and build only the finest tunnel greenhouses. We use high-quality materials during construction and customise everything to suit your specific measurements and requirements. Starting at 6.1m wide by 6m long they’re built to last from galvanised steel and designed to efficiently maintain and control an optimum growing climate to suit your needs.
Whether you’re an avid at-home gardener, setting up a nursery, or starting a market stall with fresh produce for sale, our tunnel greenhouses are sure to keep you and your plants happy.
The versatility of the greenhouse tunnels
Not only do Croft Structures Tunnel Greenhouses feature twin sliding front doors and manually controlled butterfly vents as standard to assist in airflow control and ventilation, but there’s also a range of customizable options to meet your operation’s needs.
Our fully engineered Tunnel Greenhouses offer the perfect propagation solution, with cost-effective single skinned models, to the double skinned models to help you maintain the ideal growing environment.
Like all Croft Structures, flexibility is key, starting with our range of sidewall blind options. From shade cloth sides to solarweave fabric blinds, as well as fixed wall sides that allow for the installation of shelves, benches and growing spaces, there’s an option to suit your requirements.
Multispan Roof Vented
Looking for a cost effective commercial greenhouse solution? A Croft Structures multi-span greenhouse offers your horticultural operations the space, flexibility and roof options to get the job done.
With variable wall heights, span width, vent locations and orientation we have the knowledge and ability to design, manufacture and install your ideal structure.
Our designs range from simple crop covers to fully enclosed greenhouse structures that are perfect for all crops. All our structures are made from fully galvanised steel with single or twin skin inflated polythene to provide extra insulation, reduce condensation and maximise stability of the growing environment.
Our Ventmaster model is a tall airy multipspan structure with continuous roof venting. Where as our Super Ventmaster model has a gothic shaped roof line to maximimise light and efficient condensation runoff.
Plus, they’re big. Providing plenty of atmosphere above the crop and plenty of room for equipment access for tractors, you can get a Croft Structures multi-span greenhouse big enough to accommodate these needs.
Your Croft Structure multi-span greenhouse can also be engineered to include advanced ventilation, climate control, and water management systems, plus our designs are flexible enough to allow for future modifications, additions and improvements.
Choose from Croft Structures extensive range, or work with our team to design one to your needs and remember we’re happy to project manage and work with your nominated subcontractors through the build for a smooth, hassle-free build process. Engineered to Terrain Category 2 Wind regulations, our greenhouse structures are built to last!
