About our Elite Windsor lean-to greenhouses
The Windsor is a British-made aluminium lean-to with a 2010mm ridge at the wall and 1590mm eaves. Both heights exclude the optional base plinth. Its low ridge suits walls on bungalows, garages and outbuildings where height is limited. Compare our Elite greenhouses or browse the wider lean-to greenhouse range.
Our April to September 2026 paid-order data records Elite lean-tos in 69 orders, with Windsor models in 14. The 4x6 horticultural Windsor was most ordered, with four paid orders. The 4x8 toughened and 4x12 toughened each appeared in two paid orders. When choosing a position, start with our lean-to buying and positioning guide.

How to choose your Elite Windsor lean-to greenhouse
Start with wall height and depth. The Windsor is 1297mm deep, with lengths of 4ft, 6ft, 8ft, 10ft, 12ft, 14ft, 16ft, 18ft and 20ft. Choose Easygrow if you need less depth. Compare Kensington 4ft if you have clearance for its 2235mm ridge and want 1800mm eaves.
Choose between 3mm horticultural glass, 3mm toughened safety glass and 6mm polycarbonate. The toughened glass is Grade A and meets EN12150. We recommend deciding on glazing before comparing prices across sizes. The 4x8 horticultural model is £559, while the 4x8 toughened model is £799.
Plan access before choosing the door end. The single sliding door has a 600mm x 1600mm opening and can be fitted at either end. The 4x4 and 4x8 each have one opening roof vent. Built-in gutters are included.
The standard frame is silver aluminium. There are 10 powder-coated finishes: green, black, brown, grey, white, olive, navy, stone, mocha and berry. Allow for the optional base plinth when checking height. Use our greenhouse base preparation guide before preparing the footprint.
🔧 Matt's installation tip: check the footprint and overhead clearance
When fitting this model, we recommend measuring the base area and wall clearance before choosing your size. The 4x4 needs a minimum base size of 1297mm x 1300mm. The 4x8 needs 1297mm x 2578mm. Check clearance above the 2010mm ridge, with extra height allowed for any optional base plinth. Choose the door end with its 600mm x 1600mm opening in mind.
