Your garden, whatever the weather brings
A hardtop polycarbonate gazebo transforms how you use your garden — not just in summer, but across every season.
Imagine a late October afternoon, rain tapping on the roof above you, a warm drink in hand. The garden is still yours.
Whether it's a quiet morning with a book or an evening with friends, this is the space that makes it possible.
The 6mm polycarbonate roof is the core of this gazebo's all-weather performance. It blocks UV rays to UPF50+ standard and sheds rain cleanly, so the space beneath stays dry and comfortable.
The powder-coated aluminium frame is built to handle a snow load of 91kg and wind speeds up to 39–49 km/h — equivalent to a strong breeze on the Beaufort scale. Clear snow promptly after heavy falls to keep the structure performing at its best.
Installation works on most garden surfaces. Expansion screws anchor the gazebo to hard surfaces such as paving or concrete; ground stakes secure it on lawns. For timber decking, specialist wood expansion screws are recommended to avoid splitting.
Assembly is fully flat-pack and takes around 3 hours with two people. Clear instructions are included throughout.
