Royal Antique Orangerie Greenhouse

The Janssens Antique Orangerie greenhouse offers a breathtaking, T-shaped European footprint designed specifically for installation on a custom masonry or stone stemwall. This classic architectural integration allows you to ground the structure with permanent, estate-style stonework, delivering a timeless look that recalls the grandest historical conservatories. The expansive multi-wing layout provides generous, light-filled space for both sophisticated plant cultivation and elegant garden leisure.

Crafted in Belgium by Janssens—a legendary family company with over 75 years of master greenhouse craftsmanship—the Antique Orangerie perfectly blends European design heritage with high-performance modern engineering. With a layout that allows completely flexible door and window placement, you can tailor the space to seamlessly align with your garden’s workflow, aesthetic presentation, and natural environment.

Signature Engineering & Architectural Highlights:

• Stemwall-Ready Configuration: Engineered specifically to integrate flawlessly with a low stone, brick, or concrete stemwall, offering an elite, permanent custom appearance.

• Grand T-Shaped Footprint: A majestic cathedral-style layout providing distinct wings for multi-zone cultivation, an exquisite garden lounge, or a beautiful outdoor entertaining pavilion.

• Elite 17-Gauge Framework: Fabricated with an industrial-grade 17-gauge aluminum framework and heavy-duty stainless steel hardware to ensure unwavering structural integrity through wind, hail, and harsh winter conditions.

• Premium Glazing: Wrapped entirely in full-size 4mm tempered safety glass panes, maximizing light transmission and providing crystal-clear views of your landscape.

• Tailored Ventilation Flow: Features fully adjustable window and smooth-gliding door placement options, giving you absolute control over air movement and layout functionality.

When you invest in a Janssens structure, you are not just purchasing a greenhouse—you are adding a permanent architectural asset to your estate. For over 75 years, Janssens has been Europe’s premier manufacturer of luxury glass greenhouses, engineered in Belgium to meet the highest standards of beauty and durability.

• Architectural Glass: Unlike flimsy polycarbonate panels that discolor, scratch, and cloud over time, Janssens uses 4mm tempered safety glass. It provides crystalline clarity, superior insulation, and is rubber-sealed to be completely wind and watertight.
• Industrial-Grade Framework: Built with heavy-duty, thick-gauge aluminum profiles, these structures are engineered to withstand extreme weather. They handle heavy winter snow loads and high wind gusts that would compromise standard hobby greenhouses.
• Superior Ventilation & Design: The steep 38-degree roof pitch isn't just a classic English look—it maximizes interior headspace, allows optimal light penetration, and works alongside the integrated roof vents to handle heat distribution perfectly.
• Built for Generations: Every joint, gutter, and condensation channel is seamlessly engineered into the frame. Low-maintenance and rust-proof, a Janssens greenhouse is designed to look as striking in thirty years as it does the day it is assembled.
