If you’ve ever stood under a post frame pavilion while a summer rain rolled off the steel roof, you already know it’s more than just a structure. It’s a place for connection. Whether it’s sheltering a backyard gathering, storing hay and equipment, or serving as a covered court or classroom, a pavilion built the right way adds lasting value to your property.
At DIY Pole Barns, we’ve helped folks build pavilions for just about every use you can imagine. This guide walks you through the key considerations, explained clearly and practically, with the voice of experience to help you get it done right.
Why Choose a Post Frame Pavilion?
Post frame construction is strong, flexible, and time-tested. It gives you wide open space with fewer materials and faster build times. A post frame pavilion is a natural fit for many different purposes:
- Outdoor worship services
- Hay or equipment storage
- Covered basketball or pickleball courts
- Picnic shelters and event spaces
- Backyard shade structures
- Lunch shelters or outdoor classrooms
- RV or boat storage
With the right design and site preparation, your pavilion will be built to last for decades.
Sizing and Site Planning
Plan with Room to Grow
The most common thing we hear from customers is, “I wish I had made it bigger.”
The best advice? Figure out what you need, then double it. Once your pavilion is built, you’ll find more ways to use it than you expected. A little extra room up front saves you a lot of regret later.
Use Drives Design
Whether you’re covering a gathering, storing equipment, or creating a multi-use space, start with how you plan to use the pavilion. Consider table layouts, vehicle sizes, or open floor space.
Also consider ceiling height:
- 8 to 10 feet for standard use
- 10 to 12 feet for vehicles or sports
- 14 to 16 feet for RVs, hay storage, or large equipment
Pick the Right Spot
Choose high, level ground that drains well. Make sure there’s enough clearance from other buildings and future additions. Leave 50 to 75 feet of buffer if possible. Orient the structure to block prevailing winds or take advantage of natural shade and airflow.
Test your soil before setting posts. Not sure how? Check out our blog on Soil Types and Post Frame Building.
Foundation Options
Your pavilion can be built on dirt, gravel, or concrete, depending on how you plan to use it. Many customers use dirt or gravel for hay storage or basic shelter. A concrete pad is ideal for events, sports, or easy cleanup.

Anatomy of a Pavilion
- Posts: Pressure-treated 6x6s or laminated columns provide vertical support.
- Truss Carriers: Also called headers or girders, these horizontal beams sit on top of the posts and support the trusses.
- Trusses: Pre-engineered to meet your snow and wind loads. They span the full width and create an open, obstruction-free space.
- Purlins: Run horizontally across the trusses to support the roofing panels.
Roofing and Ceiling Options
We use 29 or 26-gauge G-Rib panels, featuring a 9-inch rib spacing and 36-inch coverage. These exposed fastener panels are strong, weather-resistant, and available in a range of colors.
Some customers choose to install painted steel ceiling panels underneath. These create a clean, finished look, discourage birds from nesting, and help reduce wind uplift by preventing air from pushing up under the roof.
Wind Protection That Matters
A strong pavilion stands up to the weather. Here’s how we protect against wind uplift:
- Posts are set at least 4 feet deep
- Structural truss screws secure the trusses to the top of the wall
- Diagonal bracing strengthens the frame
- Roofing panels are fastened with screws
Keep Birds Out
Birds in your trusses can lead to nests, mess, and long-term damage. You’ve got a couple of good options: bird netting stretched below the trusses, or painted steel ceiling panels that seal off the underside of the roof. Either one will do the job on its own. Visual or audio deterrents can be added if needed.
Inspect regularly and maintain as needed to keep your structure clean and usable year-round.
Permits and Common Pitfalls
Before you begin building, check with your local permitting office. You’ll need to understand:
- Setbacks from property lines
- Total lot coverage limits
- Any HOA or zoning rules
Skipping this step can lead to delays or costly changes. In places like Hinsdale, Illinois, setback and coverage rules are strict.
Avoid these common mistakes:
- Building too small
- Skipping grading or compaction
- Using cheap fasteners
- Ignoring wind or bird protection
- Forgetting to plan for lighting or storage
We’ve seen these problems, so you don’t have to.
