Your garden, sheltered and styled for every season.
A hardtop polycarbonate gazebo changes how you use your garden. Beneath its dark, structured roof, there's a sense of permanence — a room without walls that belongs outside as much as it does to the house.
Picture a warm July evening: the curtains drawn back, the table set, the light fading slowly over the lawn. Or a grey October afternoon, rain tapping quietly on the roof above while you sit dry underneath.
This is a space that earns its place through every season — not packed away in autumn, but lived in.
The 6mm polycarbonate roof panels block 99% of UV radiation and shed rain efficiently thanks to a sloped profile that prevents pooling. The powder-coated aluminium and steel frame is both rust and water resistant, built to remain outdoors year-round without deterioration.
The gazebo is rated to a total roof snow load of 100kg and a wind resistance of Level 6 (up to 49km/h), making it a credible permanent installation for UK conditions — not a seasonal shelter.
Four curtain panels and four independent mosquito nets give you full control over privacy and airflow. Close the curtains for an intimate evening setting, or drop the nets alone to keep insects out while keeping the view open.
Assembly requires 2–4 people and takes approximately 2–3 hours. Ground stakes are included for lawns; expansion screws for hard surfaces. For timber decking, specialist wood screws are recommended to avoid splitting (not included). 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 restrictions.

Frequently Asked Questions
Yes — this gazebo is designed for permanent outdoor installation. The powder-coated frame resists rust and water ingress, and the polycarbonate roof is rated to handle a total snow load of 100kg and winds up to Level 6 (49km/h). No seasonal dismantling is required.
Yes. The 6mm polycarbonate hardtop is water resistant and features a sloped profile that channels rainwater away from the structure, preventing pooling on the roof. It also blocks 99% of UV radiation, making it effective in both wet and sunny conditions.
Yes — the four mosquito nets and four curtain panels are separate and can be used independently of one another. You can close the nets for insect protection while keeping the curtains open, or draw the curtains fully for privacy. Both can be tied back when not needed.
Assembly is recommended with 2–4 people and typically takes 2–3 hours. A full assembly manual is included in the box. Given the 85kg total weight and the size of the frame panels, having at least two people present is strongly advised.
In most cases, no. This gazebo falls under permitted development rights and does not require planning permission for standard residential gardens. However, if your property is listed, in a conservation area, or has had permitted development rights removed, it's worth checking with your local council before installation.
The gazebo is suitable for all surfaces. Ground stakes (included) are used for lawns and soft ground; expansion screws (included) are used for concrete or paving. For timber decking, specialist wood expansion screws are recommended to avoid splitting — these are not included and will need to be sourced separately.
The frame is constructed from powder-coated aluminium and steel, which provides strong resistance to rust, water, and surface corrosion. The polycarbonate roof panels are anti-fade and UV-stabilised, so the structure is designed to retain its appearance through prolonged outdoor exposure.
