Discover the difference between a greenhouse kit and a greenhouse experience. At Planet Greenhouse, we've spent years helping gardeners like you find the perfect greenhouse kit—not just for this season, but for decades to come.

Premium Greenhouse Kits Built to Last

Our greenhouse kits aren't the flimsy, temporary structures you'll find at big-box stores. We specialize in luxury Victorian greenhouse kits from Janssens, a Belgian manufacturer with over a century of craftsmanship. Each kit features heavy-duty powder-coated aluminum frames, your choice of 4mm tempered glass or 10mm polycarbonate glazing, and a 15-year warranty that backs up our promise of quality.

What Makes Our Greenhouse Kits Different?

When you choose a greenhouse kit from Planet Greenhouse, you're investing in:

Exceptional Durability - These aren't seasonal structures. Our Janssens greenhouse kits are engineered to become permanent fixtures in your garden, withstanding harsh winters and summer heat with equal grace.

True Year-Round Growing - Extend your growing season indefinitely. Whether you're protecting exotic plants through freezing temperatures or starting seedlings months ahead of spring, these kits give you complete control.

Flexible Sizing Options - From intimate 7'9" x 10'2" models perfect for serious hobbyists to expansive 20' x 60' custom greenhouse kits that can double as event spaces, we have options that scale with your ambitions.

Hybrid Glazing Technology - Can't decide between glass and polycarbonate? Our hybrid greenhouse kits give you both—tempered glass walls for clarity and beauty, paired with a polycarbonate roof for superior insulation.

Greenhouse Kits for Every Vision

Victorian Greenhouse Kits

Our signature collection. These elegant structures combine Old World aesthetics with modern engineering. The Victorian style isn't just beautiful—the steep 45-degree roof pitch ensures snow slides off naturally, while the classic design increases property value. Explore the full range of Janssens Victorian greenhouse kits.

Cedar Greenhouse Kits

The Alton Cedar Cheltenham brings 100 years of manufacturing expertise into a practical, stunning design. Grade 1 Western Cedar frames rest on protective aluminum bases, combining natural beauty with lasting durability.

Custom Greenhouse Kits

Have a specific vision? We work with you to design custom greenhouse kits up to 20' x 60'. Perfect for serious growers, commercial applications, or creating a unique garden pavilion.

From Planning to Installation—We're With You

Here's what intimidates most people about greenhouse kits: the foundation. The accessories. The installation. The unknowns.

We get it. That's exactly why we guide you through every decision:

• Foundation recommendations tailored to your climate (we typically suggest an 8" concrete strip foundation with corner anchoring to your frostline)
• Temperature regulation guidance including exhaust fan placement and lexan panel installation
• Accessory selection based on how you'll actually use your greenhouse—not just what sounds nice

You're not buying a kit and getting abandoned with a confusing manual. You're gaining a partner who understands that this greenhouse represents your gardening dreams.

Built for Gardeners Who Know Quality

Our greenhouse kits appeal to gardeners who've been at this long enough to know the difference between adequate and excellent. You've probably already had a cheaper greenhouse—and learned its limitations. You understand that the right structure isn't an expense, it's an investment in years of reliable growing.

These are greenhouse kits for people who:

• Want to grow year-round, not just extend the season by a few weeks
• Need to protect valuable or exotic plants that require precise conditions
• Appreciate craftsmanship and aren't looking for the cheapest option
• Plan to pass this greenhouse down to the next generation
