Choosing the Perfect Garden Pergola
A pergola is more than just a decorative frame; it is a structural investment in your outdoor lifestyle. Whether you prefer the natural, traditional charm of a timber kit or the sleek, bioclimatic versatility of an aluminium louvered system, our collection is curated for durability in the British climate. If you are looking for a structure to attach directly to your property, explore our Patio Covers, or for a fully enclosed waterproof solution, browse our Garden Gazebos.
Timber vs. Aluminium Pergolas: Technical Comparison
Deciding on the right material depends on your maintenance preferences and desired functionality. Below is a breakdown of how our ranges compare:
| Feature | Timber Pergolas | Aluminium Louvered |
|---|---|---|
| Maintenance | Requires annual treatment/staining | Zero maintenance (Powder-coated) |
| Weather Protection | Shade only (Open rafters) | 100% Waterproof when closed |
| Longevity | 10-15 years (Pressure treated) | 25+ years (Rust-proof) |
| Price Point | Entry-level / Budget-friendly | Premium / Investment |
Why We Chose This Range
“We’ve curated this pergola range to solve the biggest issue with outdoor structures: the British wind. Many budget pergolas use thin-walled aluminium that rattles or buckles in a gale. We chose the Palram Canopia and bioclimatic ranges because they utilize thick-gauge, powder-coated aluminium and reinforced rafters. These aren't just decorative; they are engineered structures designed to withstand 75mph winds when the louvers are open, making them a permanent upgrade rather than a seasonal accessory.”
— Matt, Founder of Greenhouse Stores🔧 Matt's Installation Tip: Hidden Drainage & Footings
Modern aluminium pergolas feature clever internal guttering systems where water drains through the legs. To ensure this works, your base must be 100% level; even a 5mm tilt can cause water to pool in the rafters rather than flowing to the downpipes.
Crucially, do not simply sit a pergola on top of paving slabs. The 'sail effect' in high winds is significant. We recommend concrete pad foundations (400mm x 400mm x 400mm) under each leg, even if you are tiling or decking over the top later. This ensures your pergola stays grounded during winter storms.”
Frequently Asked Questions
-
Are pergolas waterproof?
Traditional timber pergolas with open rafters are designed for shade, not rain protection. However, our Aluminium Louvered Pergolas are 100% waterproof when the slats are fully closed. They feature integrated guttering that channels water down through the legs, keeping the area beneath dry during rain showers.
-
Do I need planning permission for a pergola?
In most cases, pergolas fall under 'Permitted Development' and do not require planning permission, provided they are under 2.5m tall if placed within 2m of a boundary, or under 3m tall elsewhere. Always check with your local council if you live in a Conservation Area or a Listed Building.
-
Can a pergola be attached to a house?
While most of our pergolas are freestanding, many can be positioned flush against a wall. If you require a structure that is physically bolted to your house wall for a 'lean-to' effect, we recommend viewing our dedicated Patio Covers range.
