Cathedral Victorian Greenhouse with Large Cupola:

The majestic Cathedral is one of our largest greenhouses, and distinguished by a cupola.  It features significantly more floorspace than even the VI 46. Like all Janssens models its 4mm tempered glass and aluminum frame make it resilient enough to withstand wind gusts and most hail. The Cathedral’s structure is additionally reinforced by thick aluminum portal frames which span its entire width, increasing its durability in sustained winds and snow events. Moreover its doors and windows can be installed nearly anywhere, providing substantial flexibility in design.

If you’re searching for a true backyard showstopper that is both beautiful and durable, the Cathedral is the one to pick.

Please note that we keep a limited stock of Cathedral greenhouses on hand, so lead times may be longer than those of other models.

 Special feature: 2 heavy duty aluminum reinforcement supports (across the width) - 2.3" W x 5.2" D. 

Greenhouse is 15' W x 19'11" L x 12'2" H, side walls are 6'8" H.

Also includes 10'2" L x 5'4" W cupola with pre-welded frame (horizontal part).
