Your garden, whatever the weather.
A hardtop gazebo this size changes how you use your garden. Breakfast on a drizzly Saturday morning, a long lunch that stretches into evening — the space is there, sheltered and ready, without you having to check the forecast first.
The dark aluminium frame and tinted polycarbonate panels sit quietly in a garden rather than dominating it. It looks considered, not temporary.
Draw the curtains for an intimate dinner. Tie them back and let the garden in. The choice is yours, season after season.
The 6mm polycarbonate roof panels are rated to handle a 100kg snow load across the whole roof and are tested to Windproof Level 6 — equivalent to a strong breeze at up to 49km/h. That covers the vast majority of UK weather conditions throughout the year.
The roof's anti-UV coating blocks 99% of UV rays, so the space stays comfortable on hot days without the greenhouse effect you get from glass. The sloped pitch sheds rainwater efficiently — no pooling, no dripping through.
Each side panel features a zip-close mesh curtain to keep insects out, with a separate fabric curtain over the top for privacy and shade. Both layers can be fully tied back when you want an open feel.
Assembly requires 2–4 people and typically takes 2–3 hours. The kit includes ground stakes for lawns and expansion screws for hard surfaces. Planning permission is not generally required under permitted development rights — though it's always worth a quick check with your local council if you're unsure.

Frequently Asked Questions
In most cases, no. Garden gazebos of this type typically fall under permitted development rights in the UK, meaning planning permission is not required. That said, rules can vary depending on your property type, location, or whether you live in a conservation area — so it's always worth a quick check with your local council if you're unsure.
The 6mm polycarbonate roof panels are rated to a 100kg snow load across the whole roof and tested to Windproof Level 6, which covers wind speeds of up to 49km/h — typical of a strong UK breeze. The sloped pitch channels rainwater away efficiently, and the anti-UV coating blocks 99% of UV rays to keep the interior cool in summer.
Yes. Each side panel has a dedicated zip-close mesh curtain designed to create a sealed, insect-free enclosure — including midges. The mesh zips closed independently of the fabric curtains, so you can have full insect protection while still enjoying airflow and natural light.
Assembly typically takes 2–3 hours with 2–4 people working together. The gazebo arrives flat-packed across 5 boxes and includes a full assembly guide. Given the size and weight of the components, we'd recommend having at least 2 people for the frame-raising stages.
Yes — the kit includes both ground stakes for lawns and expansion screws for hard surfaces such as concrete or paving. For wooden decking, we recommend using specialist wood expansion screws to avoid splitting the timber; these are not included and will need to be sourced separately.
It's designed to be a permanent outdoor structure rather than a seasonal one. The powder-coated aluminium frame resists corrosion, the polycarbonate roof handles rain, wind, and snow load, and the UV coating prevents the panels from fading or yellowing over time. Many customers leave theirs up throughout the year, though covering or storing the curtains over winter will extend their lifespan.
