Cathedral 15X12X20.ft Victorian Greenhouse

SPACIOUS. FLEXIBLE. LUXURIOUS

The Cathedral is one of our largest greenhouses, featuring a distinctive cupola that enhances height and curb appeal. With a wider footprint than the Royal Victorian line, it offers significantly more floorspace. 

The Cathedral’s flexible design allows doors and windows to be installed anywhere. If you seek a stunning, durable backyard showstopper, the Cathedral is the ideal choice. Note that lead times may be longer due to limited stock.
