A garden room that stays put, whatever the weather.
A hardtop garden gazebo transforms a patio into a proper outdoor room — somewhere to linger over a long lunch or unwind on a warm evening without watching the sky.
The beige curtains soften the light inside and give the space a settled, considered feel. Draw them back on a clear day, close them against a cooler breeze — the space works around you.
Come spring through early autumn, it earns its place in the garden every week.
The polycarbonate roof panels are UPF30+ rated and tinted, filtering UV while keeping the space beneath bright rather than dim. The two-tier design lets warm air escape through the upper vent, which makes a real difference on still summer days.
The powder-coated aluminium frame resists rust without the weight of steel — useful during a two-to-three person assembly that takes around three hours on a level, solid surface.
For hard standing, expansion screws give a wind rating of Level 5–6. Ground stakes suit lawns and softer ground, rated to Level 4–5. The structure also handles a snow load of 20kg/㎡, so it earns its keep through milder winter spells too.
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 any restrictions.

Frequently Asked Questions
In most cases, no. A hardtop garden gazebo of this size typically falls under permitted development rights in the UK, meaning planning permission is not required. That said, rules can vary depending on your property type or location, so it's worth a quick check with your local council if you're unsure.
At least two adults are recommended for assembly, and three is preferable given the size of the roof structure and frame sections. Assembly takes approximately three hours on a level, solid surface. Full instructions are included.
Yes — the 3x3m footprint and 193cm beam height make it a practical choice for covering a hot tub with surrounding access space. The waterproof polycarbonate roof and enclosed curtain sides help manage steam and provide privacy. Ensure the base is level and the structure is properly anchored before use.
The polycarbonate roof is fully waterproof and the frame achieves a wind rating of Level 5–6 when fixed to hard standing with expansion screws, or Level 4–5 with ground stakes on softer ground. Proper anchoring is important — always secure the gazebo before use and during periods of high wind.
Yes, the polyester curtains and mesh sidewall panels are removable. This makes them easy to take down for storage during winter or when you want a more open feel in the space. The gazebo frame and roof can be used independently without the curtains attached.
