Shopping for a costco gazebo 12×16 usually means you want real shade, a covered seating area big enough for family dinners, and something that won’t look temporary. The catch is that warehouse inventory rotates, and the exact 12×16 you saw online may not be in your local store. If you want a cedar gazebo in that same footprint with proven, straightforward assembly, the Backyard Discovery Barrington 16′ x 12′ Cedar Wood Outdoor Gazebo is a strong alternative that hits the same use case.
Functionally, 12×16 gives you room for a full dining table or sectional plus a grill cart, while still fitting most patios. Expect roughly 192 sq ft of roof coverage—enough to create a true outdoor room. With Backyard Discovery, you also get pre-cut, pre-drilled cedar and organized hardware, which makes the project realistic for two people in an evening or two depending on pace and site prep. Our on-site build experience mirrors the process you’ll see in the embedded 4K video below.
Why consider the Barrington 16′ x 12′ instead of waiting on a Costco restock?
Backyard Discovery focuses on cedar gazebos and grill shelters, and their Barrington line is designed for backyard living rooms and parties. The 16′ x 12′ size aligns directly with the 12×16 footprint many shoppers want. Here’s why it fits:
- Space planning: Seats 6–8 at a dining table or a sectional with side chairs; plenty of walk-around room.
- Materials that last: Naturally rot-resistant cedar with corrosion-resistant hardware and sturdy steel roof panels for year-round coverage.
- Straightforward assembly: Pre-drilled posts, clearly labeled beams, and packaged fasteners minimize guesswork.
- Brand confidence: Backyard Discovery has a long history, a solid warranty, and broad size options if your patio is tighter or wider.
If your patio isn’t quite 16 feet wide, Backyard Discovery also makes the Barrington 14′ x 12′ and 14′ x 10′. They share the same design language and assembly approach. But if you’re targeting that classic 12×16 feel you often see at warehouse clubs, the 16′ x 12′ Barrington is the match.
Planning tips for a 12×16 patio gazebo
- Footprint and clearance: Measure post-to-post spacing and allow at least 3 feet of walkway around furniture edges.
- Anchoring: Plan for proper anchors into concrete, pavers over concrete, or properly set footings. Good anchors are the secret to a solid-feeling structure.
- Orientation: Face the hip roof’s long side toward prevailing sun for better shade coverage in late afternoon.
- Utilities: If you’ll add string lights or a fan, pre-run a weather-rated conduit and confirm your local electrical code before assembly.
- Permits and HOA: A quick call can save headaches; gazebos are often allowed but may have height or setback rules.
Assembly: what to expect
Two capable homeowners can handle the Barrington with a pair of ladders, a socket set, drill/driver, and a rubber mallet. The process is methodical—posts and beams first, then rafters and roof panels. Because parts are pre-cut and pre-drilled, you’re aligning holes rather than inventing solutions. As always, lay out hardware by step, keep impact drivers on low settings to avoid over-torquing, and don’t fully tighten until the frame is square.

In the 4K video below, you can see how the pre-cut, pre-drilled cedar pieces fit together, how the hardware is organized, and how manageable the process is for just two people. The fresh cedar smell, solid posts, and overall build quality are a big part of why we like Backyard Discovery so much.
If you want to see more photos and details from this exact build, Preston also wrote about the process on his personal site: PrestonShamblen.com/backyard-discovery-arcadia-gazebo-setup. It includes tips, notes, and behind-the-scenes details from the same evening.
