Low Threshold Base

Elite Low Threshold Greenhouse Base

Door Handle and Key Lock

Elite Door Lock and Key

Elite Greenhouses now have a handy door handle to make opening your greenhouse easy as well as a proper key lock for security in your garden or on the allotment.

Diamond Shelving and Staging - Optional

Elite Integral Gutters

The superb Diamond shelving and staging is designed specifically to fit into Elite greenhouses. It’s rigid and hard wearing and built to last. The Staging is supported by cantilever bracing so there are no legs to get in the way. This leaves space underneath to grow plants, store pots and makes using the greenhouse for wheelchair users completely practical. Both staging and shelving can be colour coded to match your new greenhouse.

Crestings and Finials

Greenhouse Crestings and Finials

This greenhouse features beautiful crestings in a colour to match your greenhouse, giving it a traditional Victorian greenhouse look.

Toughened Safety Glass

Toughened Glass is much stronger than Horticultural glass and won't crack. If it does break it disintegrates into hundreds of small pieces that are unlikely to cause injury, unlike Horticultural Glass which breaks into shards. It's heavy weight also means it's the best glazing option for windy spots and the UK in general!

Full Length Glass (Long Pane)

Toughened Glass is long pane, meaning each panel in your greenhouse is one piece of glass. No unsightly overlaps where dirt and grime can collect and no Overlap Clips to worry about.
