Your garden, sheltered. Every season, every occasion.
A metal roof garden gazebo transforms how you use your outdoor space — whether that's a quiet morning coffee, a long summer lunch, or an evening with friends that stretches well past sunset.
At 3×3m, there's room to breathe. Pull up chairs, set a proper table, or simply sit and listen to the rain on the roof above you.
The mesh sides and privacy curtains mean you're sheltered from the elements and shielded from view — a genuinely private corner of your garden, whatever the weather.
The powder-coated galvanised steel roof is built to handle what British weather throws at it — rated to wind force 7 (50–61 km/h) and a snow load of 80 kg/m², so it holds its own through winter without needing to come down.
Mortise and tenon jointed roof panels make assembly more straightforward than most structures of this size. Budget around three hours and have two people on hand — the 91 kg total weight means an extra pair of hands makes a real difference.
Ground stakes are included for grass or soil. For paving or concrete, the expansion screws supplied work well on most hard surfaces. If you're installing on decking, specialist wood expansion screws are worth picking up separately to avoid splitting the timber.
At 290 cm tall and 3×3m footprint, this gazebo typically falls within permitted development rights — but it's always worth checking with your local council, particularly if you're in a conservation area or have an existing outbuilding.

Frequently Asked Questions
Assembly takes approximately three hours with two or more people. The structure weighs 91 kg across three packages, so having an extra pair of hands makes the process significantly easier and safer. Mortise and tenon jointed roof panels help simplify the build — full instructions are included.
Yes. The powder-coated galvanised steel roof is rated to wind force 7 (50–61 km/h) and a snow load of 80 kg/m², making it well suited to British weather across all seasons. The UPF 50+ rating also provides reliable sun protection during summer.
Yes. Expansion screws are included for hard surfaces such as paving and concrete. If you're installing on timber decking, we recommend sourcing specialist wood expansion screws separately to avoid splitting or damaging the boards. Ground stakes are included for grass or soil installation.
In most cases, a structure of this size falls within permitted development rights and does not require planning permission. However, rules vary depending on your property and location — it's always worth checking with your local council, particularly if you're in a conservation area or have existing outbuildings that count towards your allowance.
The gap between the two roof tiers allows warm air to escape and fresh air to circulate, keeping the space cooler on warm days. It also helps reduce wind pressure on the structure, which contributes to its stability in higher winds.
The gazebo comes with both ground stakes for soft surfaces (grass, soil) and expansion screws for hard surfaces (paving, concrete). For decking installations, specialist wood expansion screws are recommended and should be sourced separately to protect the timber.
