The Backyard Discovery Evanston Wall-Mounted Louvered Pergola attaches directly to the house and covers a patio with an adjustable louvered roof on a powder-coated galvanized steel frame. It is sold in four widths (14, 16, 18, and 20 ft), all projecting 10 ft from the wall. Among wall-mounted pergolas, it publishes the highest wind and snow figures we found.
Our Verdict
We see the Backyard Discovery Evanston 14×10 as the pick for buyers who want published weather ratings, built-in power, and a complete kit from an established brand. Backyard Discovery rates it for winds up to 100 mph and up to 2,700 lb (about 12 in.) of snow in this size.
The trade-offs are weight and mixed feedback. The 14′ x 10′ lists 553.4 lb, so installation is a real construction job, and about a quarter of the ratings shared across its sizes are 1 or 2 stars.

Design and Build Quality
The frame is powder-coated galvanized steel. Galvanizing adds a zinc layer under the paint, which resists rust even if the coating is scratched, and Backyard Discovery describes the structure as maintenance-free with rust and corrosion resistance. The black finish and clean lines give it a contemporary look.
At 553.4 lb for the 14′ x 10′, it is much heavier than aluminum wall-mounted pergolas. That weight is part of why it carries strong ratings, but it also means the wall attachment and post anchoring need careful planning.
Roof and Weather Protection
The louvered roof opens with the included wand for direct sun and closes completely for shade and rain protection. Water drains through downspouts built into the posts, so it exits at ground level instead of dripping off the roof edge.
With louvers closed, the roof acts as a full cover. As with any open-sided pergola, wind-driven rain can still reach the seating area from the sides.
Stability and Anchoring
Backyard Discovery rates the Evanston for winds up to 100 mph and snow loads up to 2,700 lb (about 12 in.) in the 14′ x 10′ size; larger widths list higher snow loads. These are manufacturer figures, but they are the most complete published ratings among the wall-mounted pergolas we compared.
Ratings only apply when the structure is installed exactly as instructed. Attach it to solid framing or masonry, anchor the posts as the manual specifies, and check whether your city requires a permit for an attached structure.
Space and Everyday Use
The 14′ x 10′ covers 167.25 by 120 in., roughly 139 sq ft, enough for a six-seat dining table or a sectional with a walkway. The listed height is 87.5 in., so check the wall height under your eaves and gutters.
The patented PowerPort mounts to any post and adds three electrical outlets and three USB ports for lights, music, and devices. You still need a power source, installed by a qualified electrician on an outdoor-rated circuit.
Assembly and Installation
Backyard Discovery supplies guided instructions through its interactive BILT app. Even so, at 553.4 lb this is a multi-person build, and many buyers will want a contractor for the wall attachment.
Plan the ledger line, flashing, and post locations before the kit arrives, and confirm that nothing in the wall, such as wiring or plumbing, sits where fasteners will go.
Owner Feedback
Owner ratings are shared across the Evanston sizes: 4.2 out of 5 from 11 ratings when we reviewed it, with 76% at 5 stars and about 24% at 1 or 2 stars. That split suggests most owners are satisfied but a meaningful minority are not, and 11 ratings is too few to identify a clear pattern.

Who Should Buy It?
| Who Should Buy It? | Who Should Look Elsewhere? |
|---|---|
| Exposed sites that need published ratings | Renters or anyone who cannot attach to the house |
| Buyers who want built-in outdoor power | DIYers without help for a heavy build |
| Long walls that suit 14 to 20 ft widths | Walls that cannot carry a heavy ledger |
| Owners who want a 5-year warranty | Shoppers on a tight budget |
Final Verdict
The Backyard Discovery Evanston 14×10 stands out for its 100 mph and 2,700 lb ratings, galvanized steel frame, post downspouts, and built-in PowerPort. Its compromises are a very heavy installation and owner ratings that are positive overall but mixed. For homeowners who want the most weather-ready attached louvered pergola we found, the Backyard Discovery Evanston 14×10 is a strong candidate; compare it with other wall-mounted louvered pergolas.
