Our greenhouses are built to withstand Ireland’s unpredictable climate. The 6 mm panels, galvanised frame components, and proper foundation anchoring make this lean-to model robust and stable year-round.

Optimised for Space & Efficiency
The lean-to design means one side can be placed against a garden wall, helping to retain heat and making use of vertical space without consuming too much footprint.

Ventilation & Access
The rear vent window and front door ensure you can manage airflow during warmer days, reduce internal humidity, and maintain healthier plant conditions.
