3x3m Lean-To Pergola with Retractable Canopy for Garden or Patio, Grey

Shade when you want it, open sky when you don't.

A lean-to pergola is one of the most practical additions you can make to a garden or patio — it sits flush against your house wall, takes up no extra footprint, and gives you a proper sheltered space in minutes. The Outsunny 3 x 3m Retractable Canopy Pergola does exactly that, with a sliding polyester canopy you can open or close depending on the weather and the time of day.

The metal frame includes triangular corner supports for added rigidity, and the structure anchors to the ground with the included stakes. The UV-resistant, coated polyester canopy handles light rain and blocks direct sun — practical protection without overcomplicating things.

Frequently Asked Questions

Does a lean-to pergola need planning permission in the UK?
In most cases, no. A lean-to pergola attached to a house and under 3m in height typically falls under permitted development rights. This model stands at 224cm. Rules differ for listed buildings, conservation areas and leasehold properties — always check with your local authority before installation.

What wall types can this be attached to?
This pergola is designed to lean against a solid wall for support. It is not bolted to the wall itself — it stands independently and anchors to the ground using the included stakes and expansion screws. No wall fixings are required.

How long does assembly take?
Most customers complete assembly in 2–3 hours with two people. Triangular corner supports are included to help with alignment during build. Full step-by-step instructions are included in the box.

Is the canopy fully waterproof?
The canopy is coated for UV resistance and light rain protection. It is not designed for prolonged heavy downpours — retract or close the canopy fully during heavy rain or strong winds to protect the fabric and frame.
