Air circulation starts low down in our greenhouse but hot exhausted air can escape through the handsome full length ridge vents, located on both sides of the greenhouse for optimum air flow. Plants love air movement, you will be rewarded if you offer plenty of fresh air. To this end our vents are automated with heat sensitive cylinders and strong spring mechanisms. 6mm toughened clear glass panels allow maximum light and the openers allow maximum ventilation.

We are proud to manufacture with Accoya. It is an acetylated wood that has been thoroughly tested for dimensional stability and durability, guaranteed for 50 years untreated and even given a 70 year service life by TRADA. Accoya is so strong that it is used in the construction of bridges and even to line canals. Accoya is produced from fast growing, renewable, well-managed sources and as such has a low, even negative carbon footprint. Organically treated Accoya carries a prized FSC certification.

Large greenhouses are available in three standard widths, with the largest reaching 10ft 7 inches (3218mm) wide. Lengths are modular, meaning you can configure any length that suits your site directly in our greenhouse configurator.

Yes. Because the design is fully modular, additional length can be added at a later stage. Before ordering it is worth reading our greenhouse sizes guide to plan ahead and avoid the need for extensions down the line.

Full-length automatic ridge vents work together with low-level vents to create a chimney effect. Hot air rises and escapes at the ridge while cooler air is drawn in at ground level. The vents open and close automatically via heat-sensitive cylinders.

A high ridge and steep pitch create a larger internal air volume, which means temperature fluctuations are slower and more manageable. It also provides comfortable headroom for tall plants like tomatoes and palms. See how this works in practice in our customer stories.

Yes. The generous internal volume, natural light, and controlled climate make a large greenhouse well suited to dual use as both a growing space and a garden room for seating, relaxing, or entertaining. A greenhouse partition lets you separate the growing area from a seating zone cleanly and permanently.

Frames are available in Accoya, a sustainably sourced acetylated timber guaranteed for 50 years untreated, or in powder-coated aluminium. Both materials are chosen for structural stability over large spans without the warping or rot associated with standard timber greenhouse kits.
