Why customers choose it
Designed to sit against a house, shed or other building, drawing on the warmth of the wall behind it.
The 5x13 and 5x15 models each have a single sliding door, two roof windows and two push-out windows.
The deeper Plus models add stronger roof framing, longer roof glass and an automatic louvered window.
One roof window has an automatic opener that opens when the temperature reaches 72 degrees, and a second opens by hand.
4 mm tempered glass in substantial rubber seals insulates better than metal clips, and one-piece vertical panes stay clean.
The largest Arcadia Plus 10x15 gives you 150 sq ft, a 10' 4" peak and a double hinged door.

Free curbside freight delivery
Choose your size, color and options. Your greenhouse ships from the manufacturer's warehouse, packed for freight.
We'll contact you to set up a delivery time frame that works for you.
Delivery is by LTL motor freight on an 18-wheeler. Let us know about tight roads or low wires so we can plan ahead.
Someone needs to be there to receive the delivery. The driver does most of the work but may need a hand.
Foundations and bases are bulky, so we recommend ordering them together with your greenhouse to avoid a separate freight charge.
