Knot-free Western Red Cedar
Grade 1 Canadian cedar is dipped and sealed, with thick glazing bars and the common rot points designed out.


The Alton Cambridge T-Shaped Cedar Orangery is a beautifully designed, durable greenhouse built with the same trusted construction as the Alton Evolution range. Crafted with exceptional attention to detail, it eliminates common rot points and is guaranteed for 15 years untreated—or expected to last 30–40 years when treated.

Why customers choose it
Grade 1 Canadian cedar is dipped and sealed, with thick glazing bars and the common rot points designed out.
Roof windows open automatically at 71 degrees with no power, and louvered side windows open by hand.
A 10 ft ridge and 45 degree roof pitch give plants a better atmosphere and give you real headroom.
Single sheets of 3 mm toughened safety glass look neater, clean up faster and are safer than small overlapping panes.
Slatted shelving runs along one long side, and gutters and downpipes on both sides come standard.
An aluminum base frame keeps the cedar off the ground, and aluminum capping sheds rain.

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.
