Evenly distributed airflow for a stable growing environment.
Cultivar greenhouses feature an innovative ventilation system for optimal air circulation ensuring no hot or cold spots. Full Length Automatic roof vents work in conjunction with full length low level vents to create a chimney effect refreshing the air every two minutes. Unlike ordinary greenhouses, this system ensures a consistent circulation of air to help keep your plants healthy.

It’s not just the greenhouse that’s packed with smart design — our accessories are engineered to work seamlessly. Take our modular staging, for example. Designed for flexibility, it can be folded down when your seedlings take off, creating more floor space and extra height for growing plants. Opt for our integral potting tray, which doubles as a shallow sink for drenching plants, making watering easier while keeping your workspace tidy.

And fixing accessories has never been simpler. Our discreet screw port is cleverly designed as a subtle groove, adding an attractive shadow line to the internal frames. This smart fastening system allows you to attach grow bars, hooks, and our popular cucumber ladder with just a screwdriver – no drilling, no fuss.

Great design is as much about what you don’t see as what you do. That’s why Cultivar greenhouses feature concealed engineering, with fixings and connections neatly hidden from view. The result? Clean, uninterrupted lines that enhance the modern aesthetic – while maintaining full access for maintenance and adjustments. Form and function, perfectly balanced.

The finest structures balance form, function, and durability to handle unpredictable weather while creating the perfect growing environment. At Cultivar, we blend precision machined aluminium with sustainable wood and toughened safety glass. This creates a beautiful space built to last a lifetime, completely avoiding the rot and constant upkeep associated with traditional timber frames.

A carefully considered glasshouse dramatically extends your growing season, protecting your plants from frost, heavy rain, and fierce winds. Beyond its practical brilliance for serious gardeners, a beautifully designed bespoke structure brings timeless aesthetics to your garden, adding both joy and value to your property.

While standard structures might fade or falter over time, a Cultivar greenhouse is built for life. Driven by cutting edge engineering and an unwavering commitment to quality, our bespoke glasshouses are designed to last for decades. They provide a permanent, elegant space to grow, requiring only minimal care so you can focus on what you love most.

Creating a stable winter environment is effortless with thoughtful design. By selecting a model with superior draft proofing, incorporating a traditional brick dwarf wall for natural thermal mass, and relying on our innovative ventilation systems, you can easily regulate the internal climate. Talk to your builder before constructing the greenhouse base about incorporating services like electricity. This is best brought in to the greenhouse via a conduit under the base (rather than drilling holes in walls or the greenhouse). Having electric on hand is helpful if you want to heat the greenhouse. Our team is always here to talk things through. With our help you’ll have a precious space that protects your tender plants through the coldest months.
