Retro Royal Victorian VI Glass Greenhouse

Do you want the finest English-style glasshouse for your garden? Then the Retro Royal Victorian VI Greenhouse is the one. It’s the most popular model in Janssens’ celebrated Victorian range — a full-sized, stately glass greenhouse handcrafted in Belgium. Above all, it brings timeless old-world elegance to any backyard. So it’s as much a beautiful garden centrepiece as it is a first-class growing space.

The Royal Victorian is the full-sized rectangular model, around 1.5 feet taller than the Junior Victorian. As a result, you get generous headroom and a grand, spacious feel inside. Plus, classic touches like narrow 14″ tempered-glass panels and decorative lower wall panels give it that unmistakable Victorian character. In short, it’s a glasshouse with real presence.

Why Choose the Royal Victorian VI Greenhouse

The Royal Victorian combines old-world charm with serious modern engineering. To start, it uses thick 4mm tempered safety glass — sturdier than the 3mm glass many rivals use. So it insulates better and resists impact, wind and hail well. In addition, heavy-duty rubber gaskets secure every pane all the way around, rather than flimsy metal clips. As a result, the structure is better sealed and better insulated.

The frame matches that quality. For example, the heavy 17-gauge aluminium profiles are thicker and stronger than many competitors offer in the same class. So the greenhouse is rigid and weather-resistant, and it’s backed by TÜV and GS certification (similar to a safety listing). For comfort, roof windows with automatic openers and a louvre window keep air moving. Better still, the doors and windows can be installed almost anywhere. So you can tailor the layout to your garden.

H2: Royal Victorian vs Junior Victorian — Which to Choose?

Both are premium Janssens Victorian glasshouses with 4mm tempered glass, so the difference is size and presence. The Royal Victorian VI is the full-sized model — taller, larger and grander, with sizes up to 200+ sq ft. The Junior Victorian, by contrast, is the compact version for smaller gardens. For the largest, most dramatic option, see the Cathedral Victorian with its grand cupola, or the Victorian Orangerie with its T-shaped design. So choose the Royal Victorian if you want the classic, full-sized English glasshouse.

H2: Foundation, Siting and Setup

A premium glass greenhouse needs a solid, level foundation, and the Royal Victorian includes a foundation frame to help. Even so, prepare a level base such as concrete or treated timber first. Next, choose a sunny, well-drained, open spot. Then orient the longer side toward the sun for even light. Because it’s a substantial, made-to-order structure, check with your local council about building permits before you order. We also recommend professional assembly for the best result. For siting help, the Australian Government’s Your Home guide is excellent. The Bureau of Meteorology also helps you plan around local sun, wind and frost.

H2: What to Grow (and Do)

A bright, full-sized glasshouse opens up year-round growing and so much more. For example, you can grow vegetables, flowers, seedlings and tropical plants in every season. Plus, you can overwinter tender favourites like citrus, or use the space as a stunning sunroom, tea house or garden retreat. For season-by-season advice in Australian conditions, Gardening Australia is a trusted resource.
