Leveling a gazebo site starts with the foundation design
A flat-looking patch of ground is not necessarily a suitable gazebo foundation. Before removing soil or adding gravel, decide how the exact structure will be supported and anchored. Leveling, drainage and structural support are related jobs, but they are not interchangeable.
Use the Arcadia layout before marking the site
The Arcadia 12×9.5 manual calls for square, level footings, a concrete pad or a deck and supplies an anchoring layout. It includes concrete attachment hardware; wood-deck attachment hardware is separate, and the deck must provide adequate structural support. These instructions do not approve setting the kit directly on loose gravel or a layer of decorative pavers.
Plot both the post locations and the roof envelope. Check access, nearby structures and overhead and underground services before excavation or drilling. A foundation professional can assess soil, existing concrete, drainage, local conditions and the proposed anchor system without relying on a universal excavation depth.
A useful preparation sequence
- Confirm the model and foundation requirements, including any local approvals.
- Have the support elevations and drainage plan coordinated so the structure is correctly aligned without creating water traps.
- Construct or assess the foundation to that plan, allowing required curing or other preparation before assembly.
- Check the actual anchor layout and clear working area against the manual before drilling or placing the gazebo.
Do not shorten a post or stack improvised shims to hide an unsuitable base. If the support points cannot meet the design, correct the foundation before building. The manufacturer’s product dimensions help establish the overall fit, but nominal 12×9.5 dimensions are not a footing drawing or a material-quantity calculation.

Watch a Real Backyard Discovery Gazebo Build in 4K
Before you commit to a gazebo, it helps to see one go together in the real world. Preston and his brother built a Backyard Discovery Arcadia 12′ x 9.5′ cedar gazebo in a single evening, start to finish.
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.
Finish site preparation before timing assembly
A prepared foundation makes the assembly plan clearer; it does not guarantee an evening build. Keep foundation work, drainage corrections and approvals separate from the kit’s construction schedule. If an existing patio or deck cannot be verified, pause there rather than assuming compaction, heavier anchors or extra gravel will make it suitable.
