Bring timeless European elegance and practical growing space to your backyard with the Janssens Junior Victorian Glass Greenhouse Series. Made in Belgium, these beautifully crafted greenhouses combine a durable jet-black aluminum frame, 4mm tempered safety glass, and traditional Victorian detailing to create a light-filled retreat for plants and gardeners alike.
Available in three sizes, the J-VIC 23, J-VIC 24, and J-VIC 25 share an approximately 8ft-wide footprint, generous 5ft 2in sidewalls, and an 8ft 2in roof peak. Choose the compact 8 × 10 ft model for smaller gardens, the versatile 8 × 12.5 ft model for additional growing space, or the spacious 8 × 15 ft model for an expanded greenhouse retreat.
Each model includes a sliding glass door, heat-activated automatic roof ventilation, integrated gutters with downspouts, and a 4-inch-high foundation frame. Whether you're starting seedlings, extending the growing season, overwintering plants, or creating a charming garden sanctuary, the Junior Victorian offers a beautiful balance of function and architectural character.
