The Gigant greenhouse delivers exceptional scale and performance. Crafted in Belgium by Janssens, with a sturdy tubular aluminum frame and 4 mm tempered glass, it features a tall roofline and a vast interior, providing generous space for taller plants and projects. The design allows flexible placement of doors and windows, making it adaptable to both your space and your gardening style.
For dedicated gardeners and hobbyists, the Gigant greenhouse offers a bright, durable environment where plants thrive, and creativity flourishes. It combines European design heritage with modern engineering for lasting beauty, reliability, and year-round inspiration.
Please note: Because the Gigant can only be purchased as a customized model, a special order must be placed with the Janssens factory in Belgium. Lead times are longer than other models.

Dimensions
Since Gigant greenhouses are offered only as a special order, they have no default length or width - these dimensions may be customized within certain parameters.
The charts below show possible dimensions for the Gigant greenhouse. Note that the width of the greenhouse will determine both peak height and roof pitch.
*Dimensions are approximate conversions from metric measurements and should not be relied on for assembly purposes. Contact Exaco for more information.

1'0"
1'8"
2'11"
