Your garden, reimagined as a room worth staying in.

A hardtop gazebo changes how you use your garden. Beneath a solid galvanised steel roof, you're sheltered from a summer shower without a second thought — curtains drawn, netting down, the evening carrying on regardless. Set the table for eight, hang a string of lights from the ceiling hook, and let the walnut-grain frame do the rest. It's the kind of space that earns its place in the garden year after year. Whether it's a long Sunday lunch or a quiet morning coffee, this is outdoor living without compromise.

The galvanised steel roof is UPF50+ rated and fully waterproof, with a built-in water gutter that channels rain away from the structure rather than letting it pool. No drips, no sagging — just a dry space underneath. The powder-coated metal frame resists rust and fading, and the curtains run on a rail system so they slide open and close cleanly. The mosquito netting detaches independently, so you can use it on its own during warmer months without drawing the curtains. Assembly requires 2–4 people and typically takes 2–3 hours. It anchors to any surface — expansion screws for hard ground, ground stakes for lawn. For timber decking, use specialist wood expansion screws to avoid splitting (not included). Planning permission is not generally required as this structure falls under permitted development rights. If you're unsure, check with your local council before installation.

Frequently Asked Questions

Yes. The powder-coated metal frame and galvanised steel roof are both designed for long-term outdoor use in variable weather. The structure is rated to Wind Level 6 (Strong Breeze, 25–31 mph) and carries a UPF50+ waterproof roof. For year-round installation, anchor it securely using the included expansion screws on hard surfaces or ground stakes on lawn.

Planning permission is not generally required, as a structure of this size typically falls under permitted development rights in England and Wales. However, rules can vary depending on your property type, location, and whether you live in a conservation area. We recommend checking with your local council before installation if you have any doubt.

Assembly requires a minimum of 2 people and is recommended with up to 4 for ease and safety. The process typically takes 2–3 hours. Full instructions are included. We strongly advise against attempting solo assembly given the weight of the frame components.

Yes. The mosquito netting detaches independently from the curtains, so you can use the netting alone during warmer months for insect protection without drawing the curtains. Both the curtains and netting can also be fully removed if you prefer an open-sided structure.

The 160gsm polyester curtains should be hand-washed only. Machine washing will degrade the UV-resistant and water-resistant coating applied to the fabric. Use a mild detergent and allow to air dry fully before re-hanging to prevent mildew.

The gazebo can be anchored to any firm surface. Use the included expansion screws for concrete, paving, or other hard surfaces, and the ground stakes for lawn or soft ground. If installing on timber decking, specialist wood expansion screws are recommended to prevent splitting — these are not included and should be sourced separately.
