PLEASE NOTE: with the porch the footprint of this greenhouse is 11ft 2" (3390mm) by 19ft 11" (6070mm).

4mm Toughened glass is standard on all Swallow wooden Greenhouses and is held in special grooves within the frame and then sealed in place with quality silicone. Inward opening single door with mortise locks are also standard.

Each roof vent is supplied with Bayliss XL autovents to automatically open the roof vents when you’re not around to stop over heating. You also get two returned stagings at the front of the greenhouse for working on and storing your plants.
