The 12ft 10in x 15ft 7in x 9ft Antique Orangerie Glass Greenhouse Kit is a high-quality glass greenhouse designed for gardeners and outdoor enthusiasts who appreciate classic European aesthetics. Featuring a Victorian-style greenhouse design, this luxury glass greenhouse has the same spacious dimensions as the Janssens Royal Orangerie, but with narrower 4mm tempered glass panels (14 inches wide), enhancing its authentic vintage appeal.

Its T-shaped floor plan and dramatic 38º roof slope allow for maximum sunlight exposure, creating an ideal environment for year-round gardening, plant propagation, and greenhouse farming. The steep roof pitch also helps prevent excessive snow accumulation, making it perfect for cold climates.

The wide entry portico is slightly taller and broader than that of the Royal EOS T model, offering a more inviting entrance. A low-threshold double-hinged glass door ensures easy accessibility, while the sturdy 17-gauge aluminum frame and tempered glass panels provide exceptional durability against strong winds, heavy rain, and moderate hailstorms.

Wall Mount

Unlike most Janssens greenhouses, this model is designed for stem wall mounting. However, its sidewalls are shortened to maintain the original height when placed on a knee wall foundation, giving it a seamless and elegant finish. 

Ground Mount

This beautiful orangerie is also available in a ground mount version by special order.  The ground mount variant has the same overall sidewall height, with taller glass panels from the ground up, rather than sitting up on top of a wall.
