The Elite Classique 12ft wide greenhouse is large greenhouse perfect for large gardens, plant nurseries or educational use. Double doors are standard as are louvre vents to help ventilate your greenhouse.

The Classique 12ft x 20ft greenhouse benefits from a sturdy high quality aluminium frame with bracing and strengthening on each upright and roof bar giving class leading strength. The double sliding doors have an integral door catch to keep the door shut in high winds or open when you need more ventilation. New features for 2013 include a door handle and a proper key lock for security. The Classique is designed to sit on a raised brick base.

Elite toughened safety glass gives you peace of mind where children and pets are present and safety is top of the list. Toughened glass simply granulates if broken removing any danger of injury from shards of glass.

This Elite Classique Greenhouse 12 x 20 has 4 opening roof vents and 2 louvre vents for ventilation, a double sliding door, an 8ft long shelf and integral gutters to collect rain water.

Check out all of the options below. You can add another double door, a custom paint finish, some staging, shelving or even a new water butt !

Elite Low Threshold Greenhouse Base
Elite Low Threshold Greenhouse Base

The Low Threshold Base is unique to Elite Greenhouses. It allows you easy access with wheelbarrows and wheelchairs without having to build a ramp. No more tripping over a greenhouse base when carrying plant trays as the entry is at ground level.

Elite Integral Gutters
5 Slat Diamond Staging

The Diamond shelving and staging are designed for Elite greenhouses. They are durable, long-lasting, and supported by cantilever bracing, eliminating the need for legs. This design provides space underneath for growing plants, storing pots, and wheelchair accessibility. Both can be color-coded to match your greenhouse.

Elite Integral Gutters
Elite Integral Gutters

You’ll find proper gutters on Elite greenhouses rather than narrow channels. These are more effective at gathering up rainwater for your water butt and less likely to get blocked up with leaves.
