Knot-free Western Red Cedar
Grade 1 Canadian cedar is dipped and sealed, and every potential rot point has been designed out.


The Alton Durham T-Shaped Cedar Orangeries is an astutely designed, robust greenhouse. The finish, attention to detail and amount of material used to manufacture it, is unprecedented at this price. All of the potential 'rot points' have been designed out of the greenhouse.
This greenhouse is guaranteed not to rot for 10 years. That said, we would recommend you treat your greenhouse every 3 years, this way your greenhouse could last 30, 40 maybe even 50 years.


🌳 Area: 113 sqft

700% tougher than regular horticulture glass.

Why customers choose it
Grade 1 Canadian cedar is dipped and sealed, and every potential rot point has been designed out.
Roof windows open on their own with automatic openers, and louvered windows add a cross-breeze.
Large single panes of 3 mm toughened safety glass look neater and clean up faster than small overlapping panes.
Mortise-and-tenon joinery, stainless hardware and knee brace spandrels at every rafter keep the frame rigid.
Slatted shelves run along one long side, top and bottom, so you can start growing right away.
A low level threshold and a securely locking hinged door make everyday use simple.

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.
