Your garden, sheltered and styled for every season.
A hardtop metal gazebo transforms even a modest British garden into a proper outdoor room — somewhere to linger long after the sun dips behind the fence.
Curtains drawn against the evening chill, mesh sides keeping the midges out, ceiling hooks dressed with lanterns. It earns its place all year.
Whether it's a summer gathering or a quiet autumn afternoon, this is a structure built to stay.
The two-tier powder-coated galvanised steel roof does two jobs at once: it sheds rain efficiently while the gap between tiers draws heat and wind pressure upward, reducing stress on the frame.
Eight 8 x 8 cm steel columns anchor the structure, with both ground stakes for lawns and expansion screws for patios or decking — use specialist wood screws on timber to avoid splitting.
Assembly uses mortise and tenon roof joints, which align without specialist tools. Budget 3–4 hours with two people; the 91 kg total weight means a second pair of hands is essential throughout.
No planning permission is required under permitted development rights, though it's always worth a quick check with your local council if your property has restrictions.

Frequently Asked Questions
In most cases, no. A 3 × 3m garden gazebo falls within permitted development rights in England and Wales, meaning planning permission is not required. That said, rules can vary for listed buildings, conservation areas, or properties where permitted development rights have been removed — it's always worth a quick check with your local council if you're unsure.
Assembly typically takes 3–4 hours. Two or more people are strongly recommended throughout — not just for ease, but because the structure weighs 91 kg in total and several stages require panels to be held in position while fixings are secured. The mortise and tenon roof joints are designed to align without specialist tools.
Yes. The powder-coated galvanised steel frame and roof are built for year-round outdoor use. The structure is rated to withstand wind speeds up to Level 7 (Near Gale Force, 50–61 km/h) and a snow load of 80 kg/㎡. For prolonged periods of severe weather, removing the curtains and netting will reduce wind resistance and extend their lifespan.
The gazebo can be installed on both soft and hard surfaces. Ground stakes are included for lawns and soil, while expansion screws are provided for patios, concrete, and paving. If you're installing on timber decking, specialist wood expansion screws are recommended to avoid splitting the boards — these are not included and should be sourced separately.
Yes to both. The 120g/m² polyester curtains are water-resistant and suitable for outdoor use in typical UK weather. Each of the four curtains is individually removable, so you can adjust coverage for ventilation, light, or cleaning without taking down the full set.
The gazebo comes with a 1-year manufacturer's warranty covering structural defects. If you experience any issues within this period, please contact us with your order details and we'll arrange a resolution. Normal wear, surface weathering, and damage caused by extreme weather events are not covered under the structural warranty.
