Your garden, whatever the weather.
A hardtop gazebo changes how you use your garden — not just in summer, but across the whole year. Beneath the polycarbonate roof, there's shelter from a passing shower and shade on a bright afternoon, without losing the sense of being outside.
Set up a dining table for eight, a pair of armchairs, or a quiet corner with a book. The 3x3m footprint gives you genuine room to live in, not just stand under.
When the evening draws in, draw the curtains. The mesh nets keep insects out while the breeze moves through — a small detail that makes a real difference on a warm night.
The aluminium and steel frame is built to stay put. Ground stakes anchor it into lawn or soil; expansion screws fix it to patio, concrete, or stone. The structure is rated to withstand wind speeds up to 49km/h and carry a snow load of 100kg — reassuring for a UK garden through autumn and winter.
The sloped polycarbonate roof is designed to shed rainwater naturally, so there's no pooling or standing water after a downpour. The roof is 99% UV and water resistant, anti-fade, and anti-UV treated — it won't yellow or degrade with prolonged sun exposure.
Assembly takes 2–3 hours with 2–4 people and requires no specialist tools. Everything needed is included in the box. For wooden decking, specialist wood expansion screws are recommended to avoid splitting — these are not included and should be sourced separately.
Planning permission is not generally required as this structure falls under permitted development rights. If you're unsure about your specific situation, it's worth a quick check with your local council before installation.

Frequently Asked Questions
Assembly typically takes 2–3 hours with 2–4 people. No specialist tools are required, and a full assembly guide is included in the box. Having at least two people makes it significantly easier to hold frame sections in place while securing fixings.
Yes. The frame is rated to withstand wind speeds up to 49km/h (wind force level 6) and a snow load of 100kg, making it suitable for typical UK conditions across all seasons. The polycarbonate roof is 99% UV and water resistant and is anti-fade treated to maintain its appearance over time.
The gazebo can be installed on any standard garden surface. Ground stakes are included for lawn or soil, and expansion screws are included for hard surfaces such as patio, concrete, or stone. For wooden decking, specialist wood expansion screws are recommended to prevent splitting — these are not included and should be sourced separately.
The sloped roof design allows rainwater to run off naturally, preventing pooling or standing water after a downpour. The polycarbonate panels are 99% water resistant. As with any outdoor structure, ensuring the gazebo is level during installation will support effective drainage.
Planning permission is not generally required, as a structure of this size typically falls under permitted development rights in the UK. However, rules can vary depending on your property type, location, or proximity to boundaries. It's always worth a quick check with your local council if you're unsure.
Each of the four sides includes one curtain panel and one mesh net panel, giving you full coverage around the gazebo. The curtains provide privacy and shelter from wind, while the mesh nets allow airflow and keep insects out. Both can be tied back when not in use.
