Your garden, transformed into a place worth staying in.
A hardtop gazebo changes how you use your garden — not just in summer, but across the whole year. Whether it's a slow Sunday breakfast or an evening with friends under low light, this structure gives your outdoor space a permanent sense of purpose.
The dark grey finish and twin-tier roofline have a quiet confidence to them. From the garden, it reads as considered and architectural. Inside, with the mesh panels drawn and curtains tied back, it feels open but sheltered — a room without walls.
On cooler evenings, close the curtains and the space holds warmth. On bright afternoons, the two-tier roof draws heat upward, keeping the interior noticeably cooler than a single-skin canopy would.
The two-tier roof is the structural centrepiece. The upper vent allows warm air to escape naturally, reducing heat build-up beneath the canopy — a meaningful difference on a British summer afternoon when the sun is low and direct.
The powder-coated aluminium frame resists rust and surface degradation without annual treatment. The galvanised steel roof panels carry a 100 kg snow load rating, making this a structure you can leave standing through winter without concern.
It withstands winds up to 61 km/h and can be anchored to hard surfaces via expansion screws or soft ground via stakes — both sets included. For timber decking, specialist wood screws are recommended to avoid splitting (not included).
Assembly takes 3–4 hours with 2–4 people. The manual is structured box by box, with a parts checklist for each stage, so you can verify contents before you begin rather than discovering a missing component mid-build. Planning permission is not required under permitted development rights, though we always recommend confirming with your local council if your property has any restrictions.

Frequently Asked Questions
No — this gazebo falls within permitted development rights and does not require planning permission in most cases. However, rules can vary depending on your property type, location, or any existing restrictions. We always recommend checking with your local council if you have any doubt.
Yes. The galvanised steel roof panels carry a 100 kg snow load rating, and the structure is rated to withstand winds up to 61 km/h. It is designed to remain standing through all four seasons without needing to be dismantled for winter.
Assembly typically takes 3–4 hours and is recommended for 2–4 people. The manual is structured box by box, with a parts checklist at each stage so you can verify all components before you begin. We recommend reading through the full guide before starting.
The gazebo is suitable for all surfaces. Expansion screws are included for hard surfaces such as concrete or paving, and ground stakes are included for soft ground such as lawn. For timber decking, specialist wood expansion screws are recommended to avoid splitting — these are not included and should be sourced separately.
Each of the four sides comes with both a curtain panel and a mosquito net, giving you full control over privacy, ventilation, and insect protection. The curtains tie back when not in use, and the mesh nets can be used independently to keep insects out while maintaining airflow.
The gazebo is covered by a 1-year manufacturer's warranty against defects. If you experience any issues within this period, please contact us directly and we will manage the process on your behalf. Warranty does not cover damage caused by improper assembly, misuse, or extreme weather events beyond the product's rated specifications.
