Retro Royal Victorian Greenhouse by Janssens — A Distinctive Take on the Royal Victorian
The Retro Royal Victorian is a variation of the Royal Victorian, popular for its unique look. Often called "The Roman Bathhouse" or "Windsor Estate," it pairs decorative 4mm aluminum panels on the lower half with narrow panes of 4mm tempered glass above for a bold, vintage style. Doors and windows can be installed nearly anywhere, and it can be built on a knee wall for extra height.

Built for Strength
-
Heavy-duty aluminum frame — larger, thicker and stronger profiles than most greenhouses in its price range.
-
4mm tempered safety glass (where many brands use 3mm), TUV and GS tested for resilience to wind and hail.
-
Heavy-duty rubber seals hold every pane in place all the way around, for a tight, better-insulated structure.
-
Stainless steel hardware that won't rust or corrode.
-
17-gauge aluminum framing — resilient enough to withstand strong wind gusts, hail and a moderate amount of snow.
-
Structurally certified for wind and snow loads — see the Structural Certification under Helpful Links below.

FAQ
How is this different from the standard Royal Victorian?
Same Belgian build and roofline underneath, but the Retro swaps in narrow glass panes and decorative aluminum panels on the lower half for a bolder, vintage look.
Do I need a permit?
Often, since this is a permanent structure on a foundation — check with your local building department before you order.
How long does assembly take?
Most owners budget several days with two people, or we'll coordinate an installer for you.
