Your garden, sheltered and styled all season long

A hardtop gazebo transforms how you use your garden — turning an open lawn into a proper outdoor room you can enjoy from spring through to autumn.

Imagine Sunday lunches under a solid roof, evening drinks with the curtains drawn, or a quiet morning coffee with the mesh sides keeping insects at bay.

With four side curtains and four mosquito nets, you control the light, the privacy, and the atmosphere.

The 6mm polycarbonate roof panels are translucent, UV-protective, and water-resistant — letting natural light through while keeping rain out and protecting against sun exposure.

The powder-coated aluminium frame provides a stable, long-lasting structure across a 3m x 3m footprint, with an eaves height of 206cm giving a comfortable, open feel underneath.

Installation is straightforward on any surface: use the included ground stakes on grass or soil, and the expansion screws on patios or hard standing. For timber decking, specialist wood screws are recommended to avoid splitting.

No planning permission is required in most cases, as this gazebo falls under permitted development rights — though it's always worth checking with your local council if you're unsure.

Frequently Asked Questions

In most cases, no — this gazebo falls under permitted development rights and does not require planning permission. However, rules can vary depending on your property type, location, or local council restrictions. We always recommend checking with your local council if you're unsure, particularly if you live in a conservation area or a listed building.

Assembly typically takes 2–3 hours and is recommended with 2–4 people. The gazebo comes with a full instruction manual to guide you through the process. Having extra hands makes it significantly easier to hold the frame sections in place while securing the roof panels.

Yes — the gazebo can be installed on any surface. On hard surfaces such as concrete or paving, use the included expansion screws. On grass or soil, use the included ground stakes. If you're installing on timber decking, we recommend using specialist wood expansion screws to avoid splitting the boards.

The 6mm polycarbonate roof panels are water-resistant and will provide reliable shelter in light to moderate rain. The panels are also UV-protective and translucent, allowing natural light to filter through while keeping the elements out. The gazebo is not designed for use in heavy rain, strong wind, or snow conditions.

The gazebo is covered by a 1-year manufacturer's warranty on parts, covering manufacturing defects. This does not cover damage caused by weather events, improper assembly, or general wear and tear. If you have a warranty query, please contact our customer support team with your order details.
