How to Construct a Pavilion
Building a pavilion requires precision and structural integrity to ensure it stands the test of time (and weather). Unlike a simple DIY kit, our process is rooted in the craftsmanship of heavy timber.
1. Foundation and Anchoring
Every sturdy structure starts with a solid foundation. For our pavilions, this typically means anchoring posts to concrete footings or an existing reinforced slab. Because pavilions have solid roofs that can catch the wind, securing them properly is non-negotiable. We require the build site to be within 6 inches of level before installation begins, helping to ensure long-term stability.
2. Post and Beam Assembly
We use high-quality, solid wood timber, never hollow metal or plastic. The vertical posts are erected first, followed by the horizontal beams. This frame forms the skeleton of your pavilion. We may incorporate traditional joinery techniques along with robust hardware to ensure the connection points are both beautiful and incredibly strong.
3. Roof Construction
This is where a pavilion truly takes shape. We construct a full roof system, complete with rafters, optional tongue-and-groove ceiling boards (for that stunning view when you look up), and roofing materials that are selected to complement your home. This solid roof provides complete shade and rain protection, making your outdoor space usable rain or shine.
How to Construct a Pergola
Pergolas offer a different aesthetic and function, focusing on filtered light and open-air ambiance. While the process shares similarities with pavilions, the roof structure is distinct.
1. Setting the Posts
Just like our pavilions, pergolas begin with setting the posts. Whether we’re setting posts in concrete or anchoring them to a concrete patio, we ensure vertical perfection. This stage is crucial to a pergola's geometric beauty.
2. The Header and Rafters
Once the posts are set, we install the headers, the main beams that support the top layers. Then come the rafters, spaced to provide the shade you desire. Our designs often feature decorative end cuts, adding a touch of elegance to the structural beams.
3. Shade Slats and Finishing
The final layer involves the top shade slats (or purlins). These run perpendicular to the rafters and determine how much sunlight filters through. We can adjust the spacing to give you more or less shade depending on your preference. Finally, we apply our professional-grade Wood Defender stain to protect the timber and enhance its natural grain.

Personalized Structures
Your backyard is unique, and your structure should be too. While we have popular models like the Santa Monica or the Carport XL, we specialize in custom structures. Here are a few ways we can tailor the construction process to your lifestyle:
- Attached vs. Freestanding: We can construct pergolas that attach directly to your home, extending your indoor living space seamlessly outdoors.
- Custom Sizes: Need a specific footprint to fit a poolside deck? We build to your exact dimensions.
- Privacy Walls: We can integrate timber privacy walls during construction to block wind or neighborly views.
- Electrical Ready: If you plan to add chandeliers or fans, we can design the structure to accommodate wiring, keeping the look clean and professional.
From the moment you schedule your installation to the final walkthrough, our dedicated installation team handles the heavy lifting. We provide delivery and professional installation, so you can focus on planning your first outdoor gathering rather than worrying about tools and lumber.
