Our verdict
A lean-to pergola fixes to your house wall and extends outwards over a patio or back door — the simplest way to add permanent overhead shelter without a freestanding structure. The Outsunny wall-mounted model uses a powder-coated aluminium frame with a polycarbonate roof panel that provides full UV and rain protection. At under £300, it is the most affordable route to a genuinely waterproof outdoor cover. The 3×3 m footprint shelters a small dining set or a couple of loungers. Installation requires drilling into masonry, which is straightforward but does mean committing to a position.
