There’s something undeniably thrilling about standing in front of a structure that’s not only elegant, but undeniably engineered to grow. The first time you lay eyes on the Janssens Gigant Greenhouse, it’s not just the scale that captures your attention—it’s the presence. This is not your average backyard greenhouse. It’s a bold statement, a serious investment, and a gardener’s dream realized in glass, aluminum, and light.
For growers who need space, stability, and lasting beauty, the Janssens Gigant Greenhouse—offered exclusively through trusted suppliers like Mulberry Greenhouses—is in a class of its own. With Solar Control Polycarbonate roofing, rugged framing, and expansive square footage, it’s designed to accommodate everything from full-scale garden beds and citrus trees to entertaining spaces and winter retreats.
Whether you're cultivating tropical plants, expanding your vegetable yields, or simply creating a year-round haven for gardening and leisure, the Gigant is more than a structure—it’s a lifestyle upgrade.
What Sets the Janssens Gigant Apart?
From the very first beam to the final glass panel, the Janssens Gigant Greenhouse is designed to withstand the elements while delivering a luxury experience for the gardener. Manufactured by Janssens of Belgium and distributed in North America by Exaco, this model represents over 75 years of horticultural expertise brought to life through thoughtful design and top-tier materials.
Its name says it all—Gigant. With spans starting at 15 feet wide and customizable lengths, the footprint of this greenhouse is generous enough to feel like an extension of your home. Think walk-in comfort with room to spare for workbenches, shelving, fruiting trees, and still space left for seating. It’s the perfect solution for growers who have outgrown traditional greenhouse kits and want a permanent, performance-driven option.
Mulberry Greenhouses offers this model in a variety of layout options, all featuring extra-wide double doors, tall rooflines, and clean architectural lines that fit as naturally into a landscaped garden as they do in open countryside. The dark green or black aluminum frame provides visual contrast against both rural and residential backdrops, ensuring your investment is as stunning as it is practical.
Solar Control Polycarbonate Roof: A Smarter Growing Environment
One of the standout innovations of the Janssens Gigant Greenhouse is its Solar Control Polycarbonate roofing. Gone are the days of clear polycarbonate that turned greenhouses into saunas in the summer. This new roofing material actively reflects excess solar radiation while still allowing ample light diffusion, resulting in better temperature regulation and reduced glare.
What does that mean for you? Less overheating during peak summer hours. Less need to rush in with fans, shade cloths, or emergency watering. More stable growing conditions for your plants, and a more comfortable space for you. It’s a performance upgrade that supports year-round usability and minimizes energy input—an essential feature for today’s environmentally-conscious gardeners.
And unlike glass, which can shatter or fog over time, the Solar Control Poly panels are impact-resistant and UV-stabilized. They’re built to take on hail, wind, and blazing heat without warping or degrading. That’s year-after-year value with virtually no compromise.
Built for Growers, Designed for Life
The Janssens Gigant Greenhouse isn’t just about what it can house—it’s about how it transforms the growing experience.
Imagine walking through its double doors into a space that’s already warm on a crisp spring morning. Sunlight streams through the glass side panels, illuminating raised beds of leafy greens and dwarf citrus trees. Overhead, climbing tomatoes are supported by cross beams designed to handle the weight of vining plants. In the corner, a tidy stack of seed trays sit on modular shelving, while a drip irrigation system hums softly in the background.
It’s not just functional. It’s serene. It’s efficient. It’s exactly what a greenhouse should be.
With plenty of headroom and customizable ventilation, you can cultivate tropical plants, overwinter sensitive perennials, or turn part of the space into a sunlit studio or dining nook. Some owners have even added greenhouse heaters, string lights, and custom flooring to make their Gigant a year-round gathering space. That’s the magic of this model—it adapts to your lifestyle while anchoring your growing goals.
Why Choose the Gigant Over Other Greenhouses?
It’s true—there are plenty of greenhouse kits on the market. You can buy a small, cheap greenhouse kit and assemble it in a weekend. But few offer the long-term durability, refined design, and expansive flexibility of the Gigant.
Where lower-end models may flex in the wind or fade in the sun, the Gigant’s powder-coated aluminum frame and toughened glass sidewalls hold strong. You’re not replacing panels every few years or worrying about thermal loss. With proper care, the Gigant can last for decades.
And then there’s the look. If you’ve ever dreamed of owning a Victorian Greenhouse with a modern twist—or wanted a small glass greenhouse aesthetic at a larger scale—this is your model. It’s as much a focal point for your property as it is a utility structure.
At Mulberry Greenhouses, we’ve seen customers use their Janssens Gigant Greenhouse not just for growing but for gathering, dining, and relaxing. Its presence adds property value, architectural elegance, and endless inspiration to everyday life.
