Your garden, whatever the weather.
A 3x3m metal hardtop gazebo changes how you use your garden — turning a patio or lawn into a proper outdoor room you can rely on, season after season.
Picture a warm July evening: dinner laid out beneath the dark steel roof, curtains drawn back, the garden lit by a lantern hung from the built-in hook above.
Come autumn, close the panels and the space holds its own — sheltered, calm, and still entirely yours.
The galvanised steel roof is the foundation of this gazebo's durability. Tiled in profile and finished in a deep charcoal tone, it sheds rain cleanly and carries a snow load of up to 100 kg — reassuring for UK winters.
The rust-resistant aluminium frame is rated to Level 7 wind resistance (50–61 km/h). For exposed gardens, the included ground stakes and expansion screws anchor the structure firmly to both soft and hard surfaces.
Four privacy curtains and four mosquito nets run on separate tracks, so you can use either independently. We recommend removing the curtains during periods of high wind or when the gazebo is not in use for extended periods.
No planning permission is required — this gazebo falls within permitted development rights. If you're unsure about your specific plot, your local council can confirm.

Frequently Asked Questions
No — this gazebo falls within permitted development rights and does not require planning permission for most residential properties in the UK. If your property has specific restrictions (such as a listed building or conservation area), it's worth checking with your local council before installation.
Assembly typically takes 2–3 hours and is recommended with 2–4 people due to the size and weight of the components. A full assembly manual is included in the box. We recommend laying out all parts before you begin to make the process straightforward.
Yes — the gazebo can be anchored to hard surfaces using the included expansion screws, or to soft ground using the ground stakes. For wooden decking, we recommend specialist wood expansion screws (not included) to avoid splitting the timber.
The galvanised steel roof is rated to carry 100 kg of snow load and the aluminium frame is wind-rated to Level 7 (50–61 km/h). We recommend removing the curtains during periods of high wind or extended non-use to protect them and maintain the structure's integrity.
Very little — the aluminium frame is rust-resistant and the galvanised steel roof is built to withstand the elements. Regular cleaning with mild soapy water and a soft cloth is all that's needed to keep it looking its best and prolong its life across many seasons.
The gazebo is covered by a 1-year warranty against manufacturer defects. This covers parts that are faulty or fail under normal use conditions. For any warranty queries, please contact our customer support team with your order details.
