Your garden, sheltered and styled for every season.
A hardtop garden gazebo of this scale changes how you use your outdoor space — not just in summer, but across the whole year. Rain on a steel roof, morning light filtering through drawn curtains, the quiet of a garden evening without the midges.
The domed galvanised steel roof and warm bronze-toned frame give this structure a considered, architectural presence. It sits in a garden the way good furniture sits in a room — purposeful, not temporary.
Whether it's a dining setup for eight or a lounge corner with rattan sofas, the 9.86m² footprint gives you genuine room to live outdoors.
The domed galvanised steel roof is fully waterproof and engineered to shed rainwater efficiently — the curved profile channels water away from the structure rather than allowing it to pool. It's rated to handle a snow load of up to 100kg, and the frame is tested to Windproof Level 7 (up to 61km/h), making it a credible year-round structure for the British climate.
The powder-coated aluminium and steel frame resists rust and corrosion without requiring seasonal treatment. The four curtain panels and four mosquito nets are removable and adjustable, letting you control light, privacy, and airflow independently on each side.
Assembly takes 3–4 hours and is recommended for 2–4 people. The gazebo arrives across 3 boxes and includes 12 ground stakes for soft surfaces and 12 expansion screws for hard surfaces such as paving or concrete. For timber decking, specialist wood expansion screws are recommended to avoid splitting (not included).
Planning permission is not typically required as this structure falls under permitted development rights — but if you live in a conservation area, have a listed building, or are unsure, always check with your local council before installation.

Frequently Asked Questions
Yes — the galvanised steel roof is fully waterproof. The domed profile is designed to channel rainwater away from the structure efficiently, so water runs off rather than pooling on top. It also has a snow load capacity of 100kg, though accumulated snow should be cleared regularly.
The gazebo is rated to Windproof Level 7, which covers wind speeds of 50–61km/h (31.5–38.5mph). The powder-coated aluminium and steel frame is engineered for stability, and the included ground stakes and expansion screws anchor it securely to both soft and hard surfaces.
In most cases, no — this structure falls under permitted development rights and does not require planning permission. However, if your property is in a conservation area, is a listed building, or you have any doubt, you should always check with your local council before installation.
Assembly typically takes 3–4 hours and is recommended for 2–4 people due to the size and weight of the components. The gazebo arrives across 3 boxes and includes a manual with step-by-step instructions.
Yes — the gazebo is suitable for all surfaces. Use the included 12 expansion screws for hard surfaces such as paving or concrete, and the 12 ground stakes for lawns or soft ground.
