Arcadia Lean-To Greenhouse by Janssens — Attach It to Your Home
Want a greenhouse you can step into straight from your house? The Arcadia is a lean-to glass greenhouse designed to attach to your home, garage, shed or other structure. It shares the essential design of the Royal Victorian — and many of the same customization options — in a lean-to footprint that turns an existing wall into a sunroom, conservatory or year-round growing space.
Available in 4mm tempered glass or 10mm twin-wall polycarbonate, in Black, Fir Green, White, or a custom RAL color as a special order. Photos show some of the configuration options.

The one in-stock closeout unit above is an Arcadia Plus (10'2" x 10") with double sliding doors, 2 roof vents and a louvre window — once it sells, this size goes back to special order. Every other configuration — the narrower Arcadia (15' x 5'2", ~78 sq. ft.), another 10'2" x 10" Arcadia Plus, or any custom size — is built to order through Janssens, typically an 18–20 week lead time.

Built for Strength
-
Heavy-duty 17-gauge tubular 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.
-
Arcadia Plus reinforcement — the gutter, rafter, ridge beam and gable step up to reinforced profiles, with stronger roof framing and longer roof glass for the larger footprint.
-
Doors and windows can be placed nearly anywhere in the frame, with optional decorative panels for a more finished look.
-
Full-height single glass panes — no overlapping panels, so it looks cleaner and won't collect dirt.

FAQ
What's the difference between the Arcadia and Arcadia Plus?
The Arcadia is the narrower option at 15' x 5'2" (~78 sq. ft.), a good fit for a tight side-yard. The Arcadia Plus is 10'2" x 10' (~102 sq. ft.) with reinforced framing on the gutter, rafter, ridge beam and gable, plus a set of double sliding doors.
Can I get it in polycarbonate instead of glass?
Yes — choose 4mm tempered glass for the clearest view, or 10mm twin-wall polycarbonate for more insulation.
Does it really attach to my house?
Yes — it's purpose-built as a lean-to that attaches to an existing wall. We'll help you check the wall height and plan the attachment and foundation.
What colors does it come in?
Black, Fir Green and White are standard; custom colors can be special-ordered to match your home.
Do I need a permit?
Often, since this is a permanent structure on a foundation — requirements vary by town, so check with your local building department before you order.
