America's Leading Janssens Dealer — 100% Customer Satisfaction

If you've always pictured a proper English glasshouse in your backyard — the kind with real glass panes, a classic Victorian roofline, and enough presence to become a garden feature in its own right — this is that greenhouse. The Royal Victorian comes from Janssens of Belgium, and it's built to a noticeably higher standard than typical greenhouse kits, from the seals to the frame.

Free Shipping · Financing Available · 15-Year Manufacturer Warranty · Price Match — see below for details, or call/text us and we'll walk you through it.

Sizes & Specifications

  • VI23 (small) — 80 sq. ft.: 7'9" x 10'2" x 8'6" high, 2 roof windows, 1 louvered window — the entry point into the line, ideal for a hobby garden or first serious greenhouse.
  • VI34 (medium) — 150 sq. ft.: 10'2" x 15' x 9' high, 3 roof windows, 1 louvered window — real room to grow food and start seedlings at scale.
  • VI36 (large) — 200 sq. ft.: 10'2" x 19'11" x 9' high, 4 roof windows, 1 louvered window — our most popular size, with excellent ventilation.
  • VI46 (X-large) — 250 sq. ft.: 13' x 20' — the largest rectangular Royal Victorian, a dedicated growing space or showpiece addition to a larger property.
  • Orangerie (T-shaped): a distinctive T-shaped layout for a truly custom garden feature, rather than a straightforward step up in size.

Choose from 4mm tempered glass, double-wall polycarbonate, or a hybrid of both.

Warranty & Financing

Every Royal Victorian is backed by Exaco/Janssens' 15-year limited warranty — built to stay in your yard for the long haul, not a season or two. Financing is available if you'd rather spread out a purchase like this, and we'll try our best to beat any legitimate competitor price you've found — see our Price Match page for details.

Other Royal Victorian Styles

Looking for something different? The Retro Royal Victorian swaps in decorative lower panels for a bolder, vintage look, and the Royal Victorian Orangerie uses a T-shaped floor plan for extra square footage and a grand entrance.
