pavilion kit

Today is your day. You’ve decided to create one of the most beautiful architectural paradises right in your backyard —a nature inspired timber pavilion. Let’s start. It is going to be a fast and easy project that will be a redwood-sized success!

For all practical purposes, a well planned shade shelter such as a pavilion, pergola, gazebo —should accommodate multiple functions. Whether you have an expansive area, large enough to entertain several guests or a narrow side yard, every detail is important.


Three vital things a plan should include is how much shade coverage is needed, the applicability, and traffic flow for enduring year-round usage.

Placement of Your Shade Shelter

The largest determining factor as to where to erect your shade shelter is the landscape and established structures. The direction it faces can also play into the type of shelter — a pergola, pavilion, trellis, or arbor — which is best suited for your dream backyard getaway.

How you intend to use your outdoor space should be a consideration in where you choose to place your arbor, gazebo, pavilion or pergola.

  • For example:
    • If you are creating a backyard kitchen area, being relatively close to the indoor kitchen will be more convenient in the preparation and transportation of food.
    • For a barbecue area, place it away from active child play areas, or a sport court. You would not want to have a ball bounce over into a hot grill.

Things to include in your landscape layout on paper:

Determine the area you have to work with and what areas that you cannot change (e.g. your driveway or particular tree). Consider your budget and remember that you can finish your landscape in stages.

Your home.
Each outside boundary and its surrounding landscape.
Plants and trees.
Which way does the home face, north, east, south or west?
Utilities such as air conditioner, heating pump, and dryer vents.
Downspouts and existing irrigation systems.
Sheds, storage buildings.
The views you would like to hide or protect.
Any slopes, grades, and drainage.

Playing around with a floor plan layout to fit your unique space is a great way to determine how you can wisely use your space. If you are a party person, a good rule of thumb for comfort is 5 square feet per person. However, the beauty of an outdoor space is that the area for activities readily expand out into the yard.

Figure the area of the intended outdoor living room, by multiplying the length by the width. For example, if your outdoor room is going to be 16 feet long and 20 feet wide, the area is 320 square feet (16 x 20 = 320). If you have a room that is shaped irregularly, separate the room into square portions for ease of measurement. If you measured the room in sections, add up the square feet of each section.

In the example above, divide the square footage of 320 by 5 square feet — to fit 12.8 people with ample room to move about. Rounding down — that room should comfortably hold 12 people — with arms spread out and plenty of “personal space.” However, the occupancy will be lower with the addition of obstructions, such as tables, couches, water feature, movie screen, hot tub, barbecue, kitchen bar, fire pit, etc.

Site Prep for Your Timber Structure

Prep the build site

There can be many types of foundations for posts such as attaching to an established or new deck, a building, a concrete post base or concrete pad. We recommend sloping the ground away from the site for proper drainage and avoid water
accumulating in the finished area. If you are concerned about drainage, you can lay gravel as a sub-base before adding the foundation.

To prevent pooling of water, make sure that the site slopes out 1/8″ per foot all the way around the structure in the desired direction. Once you clear the site, you can lay the foundation.

Foundation – Pavers/Brick/Stone

If your ground is already prepared and ready, the stones can be placed right on the compacted dirt or gravel. We recommend leaving the areas around the posts unfinished until after the installation of the timber kit is complete so you can cut the pavers, brick, or stone around the posts for a clean finished edge.

Foundation – Concrete/Cement

It is recommended to pour a concrete slab that is at least 4” thick for a pergola. For a pavilion, you will need footings. You can mount your structural EarthAnchor® knife plates (or post mounts) to any type of gray cement, stamped concrete patio or footing system.

We would recommend keeping the posts of the pergola (or timber structure) off any grass area so that you don’t have to mow around the posts. The knife plate will hold the bottom of the posts above the patio about ¼” to prevent it from wicking up any standing water.

If you have any questions, comments, or concerns, our Design Consultant can help you plan for your site.

Can My Concrete Pad Hold My ShadeScape® Kit?

One of the concerns people have is when they hear how much our timber kits actually weigh.  How much load-bearing capacity a concrete block has is determined by a number of factors.  How compact is the soil, the concrete mix, the age, (the hydration and hardening process of concrete causes it to become stronger over time), the size, shape and structural content all have to be taken into consideration.

Pergola with tables
solar panel pavilion

For example, the weight that is brought to bear upon a concentrated point or when it is distributed over a wider area. A block that is used to support an individual column will bear less weight than a load distributed across a network of support from other load bearing units or columns. When weight is uniformly distributed it requires twice as much weight to break it as it would be the weight concentrated at the center.

Concrete is measured for strength in PSI meaning pounds per square inch of pressure that it can bear. A typical residential patio is 4″ thick with an average of 3000 pounds per square inch ratio. It is designed to carry more than the weight of two automobiles. The average compact car is about 3,000 to 3,500 lbs. A mid-size car, van or light truck is about 5,000 to 7,000 lbs. A full-size truck is 7,000 to 12,000 lbs.

Two automobiles covering the same amount of space far outweigh an oversized heavy duty timber frame pergola. The overall total weight of an oversized pergola is nearly 4,000 lbs. which would compute to be around 1,000 lbs. of undistributed weight for each beam. Simulating this would be like placing 4 extra large sized men standing on one corner. After the weight is uniformly distributed between three other beams the PSI is considerably less.

What if your don’t want to wait for concrete?

What if you do not have concrete yet – or maybe you would like to pour concrete later? Some prefer no concrete at all.

That is NO PROBLEM. You can have your dream deck or shade shelter with NO major construction undertaking — No BIG holes in the yard — No Waiting or Dry Time. Part of the beauty of a ShadeScape® DIY deck or pergola plan for an outdoor living area is that it can be the space can be completed, expanded in steps, and budgeted out over time. Under conventional foundation and footing methods, digging and waiting for concrete to dry is required.

Pavilion Upgrades

Extra Gables

Extra Pavilion gables help to define an entrance, and create an open view showcasing your pavilion’s impressive trusses. They are also a great way to expand your pavilion with an additional wing.

Adding extra hips or gables typically cost more than most other upgrades. This is primarily due to the additional material used and the compound angles on the dovetails.

timber frame poolside pavilion

A single small gable on a pavilion can use up to 40% more timber and it takes twice as long for our craftsmen to build. Furthermore, a hipped pavilion is nearly as complicated as a gazebo to cut out because of the multiple compound cuts and angled dovetails.

Hipped Roof

A hipped roof is a symmetrical rectangular construction with two hips meeting at either end with four sloping uniform sides meeting at a single peak. When the hip is equal on all four sides, it is sometimes called a pavilion roof or a pyramid roof. Where the adjacent sloping sides meet is the hip. The degree that the hipped roof slopes from the peak is the hips bevel. At the center of the hip roof is the king post showcasing the artisan crafted interlocking joinery.

Hipped roofs are more durable than gabled roofs. Often hips are used in more advanced architecture adding quality and solidness to a home or shade structure. Hipped roofs on shade structures are common in areas with high winds such as coastal resorts. A well-designed hipped roof structure with the mortise and tenon joint system can withstand 140+ MPH winds as well as resist significant seismic activity.

Note: If desired, you can go even further with a cross-hipped roof. For more information, please speak to your Design Consultant.

Triple Post

With Western Timber Frame’s sturdy timbers, one post is more than enough to provide adequate support for each corner. For those who want a powerful look, triple posts deliver. This upgrade is beautiful and unique.

Two Tone Stain

Two Tone Stain is very attractive on timber frame Pavilions. On darker stained pavilions, it gives a lighter feel beneath to have a light or Natural stain finish beneath the roof overhead. Below are some samples of two toned pavilion roofs.

Upgrading with a 4″ or 6″ thick vertical band of fascia creates an impressive thick looking roof above your beams.

“After researching locally for a contractor to build our outdoor pavilion with kitchen and fireplace we found Western Timber Frames. Locally everything is built out of cedar. Having plenty of experience with cedar, douglass fir really appealed to me. Cedar life expectancy down here is about 10 years. Western Timber Frames has a 25-year warranty.

Due to the size of the investment and the uncertainty of who I was buying from, My wife and I flew up to Salt Lake from Houston. We met with Brian once we arrived. A super fantastic gentleman who’s very accommodating and laid back. Brian took us around on a Saturday when they were closed and showed us actual finished products. He also gave us a tour of the plant and explained the manufacturing process. We were impressed and made the decision while we were visiting. They are legit. They are quality. Our product, we couldn’t be happier.

If I had a complaint, it would be that Brian told us it would take us 2 weeks to build, It took two old men and two young strong guys 2 DAYS!!!! It went together SOLID and without any modifications!!! Awesome engineering!!”
