Your garden, sheltered and ready — whatever the season brings.

Picture long summer evenings under a solid roof, the light softening through tinted polycarbonate panels while friends gather around the table beneath. Come autumn, the curtains drawn against the chill, the space still usable — dry, calm, and properly sheltered. This is a structure built to become a permanent part of how you use your garden, not a seasonal afterthought.

The 6mm polycarbonate roof panels are UV-rated to UPF30+ and fully waterproof, sitting within a powder-coated grey aluminium frame engineered for British conditions. The two-tier vented roof reduces heat build-up and relieves wind pressure — a meaningful design detail for a structure rated to Beaufort scale 5–6 with expansion screws. Assembly takes approximately 3 hours with two people across 14 steps, and the gazebo arrives in two boxes. Ground stakes and expansion screws are included for anchoring to lawn or hard standing. No planning permission is required in most standard UK residential settings.

Frequently Asked Questions

In most standard UK residential settings, no planning permission is required for a garden gazebo of this size. However, rules can vary depending on your property type, location, and whether the structure is considered permanent. We recommend checking with your local planning authority if you live in a listed building, conservation area, or have already used your permitted development allowance.

Assembly follows 14 steps and takes approximately 3 hours with two or more people working together. The gazebo arrives in two boxes, so it's worth having a clear space ready before you begin. Full instructions are included, and all fixings — ground stakes and expansion screws — come in the box.

Yes. The 6mm polycarbonate roof is fully waterproof and rated to UPF30+, and the aluminium frame is powder-coated for corrosion resistance. The structure is wind-rated to Beaufort scale 5–6 when anchored with expansion screws, and the roof is engineered to handle a snow load of 20 kg/m². The two-tier vented design also helps manage wind pressure during stormy weather.

Yes — all four curtains and four mosquito nets attach via hooks, making them straightforward to remove for cleaning or off-season storage. The polyester curtains are 160g weight, providing good privacy and draught protection when in use.

The gazebo comes with both ground stakes for lawn installation and expansion screws for fixing to hard standing such as paving or decking. The large 17 × 17 cm base feet help distribute load and improve overall stability regardless of which anchoring method you use.

The gazebo is covered by a 1-year manufacturer's warranty against defects in materials and workmanship. This covers structural and component faults present at the time of manufacture. For any warranty queries, please contact our customer service team with your order details and we'll be happy to help.
