Grow More Beautifully, Season After Season

Aluminum frames are lightweight, rust-resistant, and require very little ongoing maintenance—an excellent choice if you want a structure that simply endures. Wood frames offer a warmer, more architectural presence in the garden and tend to integrate beautifully into naturalistic or cottage-style spaces. Consider your aesthetic priorities alongside the practical realities of your climate and how much upkeep you're willing to do each season.

Polycarbonate panels are widely favored in modern greenhouse design for good reason—they transmit ample light while offering far greater impact resistance and better insulating properties than single-pane glass. Twin-wall or multi-wall panels in particular help retain warmth during cooler months, which is especially valuable if you're extending your growing season into early spring or late autumn. They are also considerably lighter, making the overall structure easier to assemble and anchor.

Most walk-in greenhouses are designed to be assembled by the customer on a level, stable surface—a concrete slab, compacted gravel bed, or solid paving are all commonly used options. A level base is important both for the structural integrity of the frame and for proper door alignment over time. We recommend reviewing the assembly instructions included with your greenhouse before finalising your site preparation.
