Your garden, sheltered and yours — whatever the weather brings.
A polycarbonate hard top gazebo transforms how you use your garden — not just in summer, but across the whole year.
Imagine a late September evening, rain tapping on the roof above, candles lit, dinner on the table. The space feels considered, calm, and entirely your own.
Whether it's a quiet morning coffee or a long afternoon with friends, this is the part of your garden you'll return to again and again.
The 6mm tinted polycarbonate roof filters natural light while blocking over 98% of UV rays — keeping the space bright without the glare or heat of direct sun.
A double-tier roof design draws warm air upward and out, so the gazebo stays comfortable even on the warmest days. The powder-coated aluminium frame is rated to Windproof Level 6 — a strong breeze of 25–31 mph — and carries a snow load of 15 kg per square metre.
All four sides are fitted with tinted polycarbonate curtains and mesh netting, giving you full control over privacy and ventilation. Ceiling hooks are built in for lighting or decorations.
No planning permission is required under permitted development rights, though we always recommend checking with your local council if your property is in a conservation area or has specific restrictions.

Frequently Asked Questions
No — this gazebo falls under permitted development rights and does not require planning permission in most cases. However, if your property is in a conservation area, a listed building, or has had permitted development rights removed, we recommend checking with your local council before installation.
The frame is rated to Windproof Level 6, which corresponds to a strong breeze of 25–31 mph (39–49 km/h). This rating applies when the gazebo is secured using expansion screws into a hard surface. For softer ground, ground stakes are included, though we recommend expansion screws for maximum stability in exposed positions.
Yes — the polycarbonate roof is rated to carry a snow load of 15 kg per square metre. During heavy snowfall, we recommend clearing the roof promptly to avoid excessive accumulation beyond this rating. The powder-coated aluminium frame is designed to resist corrosion through wet and cold conditions.
Assembly takes approximately 2 hours with 2 or more people. The gazebo arrives across 4 boxes and includes a full assembly manual. We strongly recommend having at least two people present — some components are large and heavy, and attempting solo assembly risks misalignment or injury.
Yes, this gazebo is suitable for all surfaces. For wooden decking, specialist wood expansion screws are required to avoid splitting the timber — these are not included and must be purchased separately. For hard surfaces such as concrete or paving, the included expansion screws are suitable. For soft ground, use the included ground stakes.
Yes — all four sides are fitted with both a curtain and a mosquito net, giving you complete control around the full perimeter. You can close all sides for privacy, open them fully for an al fresco feel, or use the mesh netting to keep insects out while maintaining airflow.
